A projector is an optical instrument that uses an optical element to magnify the contour of a workpiece and project it onto a screen. It can be used for profile measurement with transmitted light, or it can be used to measure the surface shape of the through hole and observe the surface of the part. The projector is especially suitable for measuring complex contours and small workpieces, such as clock parts, stamping parts, electronic components, prototypes, molds, threads, gears and forming tools. It has high inspection efficiency and is easy to use. It is widely used in measuring rooms and production workshops. The instrumentation and watch industry is particularly suitable.
A projector, also known as a projector , is a device that can project images or video onto a screen. It can be connected to a computer , VCD, DVD , BD , game console , DV, etc. through different interfaces to play the corresponding video signals .
The projector is currently widely used in homes, offices , schools and entertainment venues, according to different ways of working, there are CRT , the LCD , DLP different types.
The consumer market for projector products in India is mainly concentrated in large and medium-sized cities such as North India, East India and South India with relatively developed economies. Education, business, government, and home entertainment are the four major consumer groups supporting the Indian projector industry. Looking at the Indian projector market. Whether it is from the quantity, quality or variety of products, it has reached a certain degree of maturity. The popularization and application of the products makes the projector’s psychological positioning change from more professional display equipment to mass products, and the sales scale of the industry continues to expand.

CRT Three gun projector
CRT is the abbreviation of English Cathode Ray Tube, translated as cathode ray tube . As an imaging device, it is one of the earliest and most widely used display technologies. The projector can decompose the input signal source into the fluorescent screens of three CRT tubes of R (red) and G (green) B (blue) . The phosphor is amplified, concentrated, and displayed on the large screen under the action of high voltage. Color image. The optical system and the RT tube form a projection tube. The so-called three-gun projector is a projector composed of three projection tubes. Because of the use of the internal light source, it is also called an active projection method. The CRT technology is mature, the displayed image is rich in color, good in reducibility, and has rich geometric distortion adjustment ability; but its important technical indicators image resolution and brightness mutually restrict, directly affecting the brightness value of the CRT projector, so far, its brightness The value is always below 300lm. In addition, the operation of the CRT projector is complicated, especially the convergence adjustment is cumbersome, the body is large, and it is only suitable for installation in a place where the ambient light is relatively weak and relatively fixed, and it is not suitable for moving.
LCD (Liquid Crystal Display) Panasonic LCD Projector can be divided into liquid crystal panel projector and liquid crystal light valve projector. The former is the main product in the projector market. Liquid crystal is a substance between liquid and solid.
The working property is greatly affected by temperature. Its working temperature is -55 °C ~ +77 °C. The projector utilizes the photoelectric effect of the liquid crystal, that is, the arrangement of the liquid crystal molecules changes under the action of the electric field, affecting the transmittance or reflectance of the liquid crystal cell projector, thereby affecting its optical properties, and producing different gray levels and colors. image.
Because LCD projectors have better color reproduction and resolution up to SXGA standard, they are small in size, light in weight and easy to carry. They are the mainstream products in the projector market.
There are three liquid crystal panels in the projector in which liquid crystals are distributed. A liquid crystal is a substance between a liquid and a solid, which does not emit light by itself, and they are arranged neatly like pixels on a fluorescent screen.
The projector utilizes the photoelectric effect of the liquid crystal, that is, the arrangement of the liquid crystal molecules and the state of the liquid crystal molecules themselves change under the action of the electric field, affecting the transmittance or reflectance of the liquid crystal cell.
The projector can use this principle to achieve the purpose of accurately controlling the light passing through the liquid crystal cell by using an electrical signal. The light source in the liquid crystal projector is a metal halide lamp or UHP (cold light source), which emits bright white light. After passing through the beam splitter in the optical path system, the white light is decomposed into light of three elements of RGB (red, green, blue).
The light of the three elements of RGB passes through the liquid crystal at a precise position. At this time, each liquid crystal acts like a light valve, controlling the passage of light in each liquid crystal and the amount of light passing through it. The light of the three elements is like this. The lens of the projector is accurately projected onto the screen.
Which color is the color and the intensity of the light is distributed properly. In this way, an image of a colorful color constituting the same as the source image is projected on the screen. Ordinary LCD projectors have many advantages such as good color, price advantage and good brightness uniformity.
In addition, the liquid crystal light valve projector represents a high-end product of the liquid crystal projector. It uses a CRT tube and a liquid crystal light valve as an imaging device, and is a combination of a CRT projector and a liquid crystal and a light valve.
With very high brightness and resolution, it is suitable for occasions where the ambient light is strong and the projection screen is large, such as a super-large command center, conference center or entertainment venue.
DLP is the abbreviation of English Digital Light Processor, translated as digital light processor. The DLP uses a DMD (Digital Micromirror Device) digital micro-reflector as a light valve imaging device.
A DLP computer board is composed of an analog-to-digital decoder, a memory chip, an image processor and several digital signal processors (DSPs). All text images are generated through the board to generate a digital signal, processed, and digitally converted.
To the heart of the DLP system – DMD. After passing through a high-speed rotating tri-color lens, the beam is projected onto the DMD and then projected onto the large screen through an optical lens to complete the image projection.
A piece of DMD is formed by a plurality of tiny square reflecting lenses (referred to as micromirrors) arranged closely in rows and columns on an electronic node of a silicon wafer, and each micromirror corresponds to a pixel for generating an image.
Therefore, the number of micromirrors of the DMD device determines the physical resolution of a DLP projector. For example, the resolution of a projector is 600X800, which means that the number of micromirrors on the DMD device is 600×800=480,000.
Each micromirror in the DMD device corresponds to a memory that can control the micromirror to switch between two positions of ±10 degrees. Moreover, the area of each pixel on the DMD block is 16 μm × 16 and the interval is 1 μm. According to the number of DMDs used, DLP projectors can be divided into: single-chip, two-chip, three-chip.
The red, green and blue of the DMD digital signal are rotated in sequence, and the small mirror is turned on or off according to the position and color of the pixel.
At this time, the DLP can be regarded as a simple optical path system composed of only one light source and a set of projection lenses, and the lens is enlarged. The reflected image of the DMD is projected directly onto the screen, so that a vivid and bright presentation is presented to us.
Refers to the light energy output by the projector in units of “lumens” (lm). A physical quantity related to light output is brightness, which is the ratio of the light energy emitted by the surface of the screen to the screen area. The common unit of brightness is “lux” (lx, 1lx = 1lm/m2). When the light output by the projector passes, the larger the projected area, the lower the brightness, and vice versa.
The factors that determine the projector light output are projection and screen area, performance, and lens performance. Generally, the screen area is large and the light output is large. The projector with a liquid- coupled lens has good lens performance and the projector’s light output can be increased accordingly.
Horizontal scanning frequency
The movement of electrons from left to right on the screen is called horizontal scanning, Panasonic Projector also called line scanning. The number of scans per second is called the horizontal scan frequency, and the horizontal scan frequency of the video projector is fixed. The scan frequency of 15.625KHz (PAL system) or 15.725KHz (NTSC system) and graphics projector is not a frequency band;
In this frequency band, the projector can automatically track the input signal line frequency, and the phase-locked circuit realizes complete synchronization with the input signal line frequency. The horizontal scanning frequency is an important projector indicator that distinguishes the projector grade. Projectors with a frequency range of 15 kHz to 60 kHz are often referred to as data projectors. An upper limit frequency exceeding 60 kHz is often called a graphic projector.
Panasonic Projector Vertical scanning frequency
The electron beam moves from top to bottom while scanning horizontally. This process is called vertical scanning. Each scan forms an image. The number of scans per second is called the vertical scan frequency. Panasonic Projector The vertical scan frequency is also called the refresh frequency, which indicates the number of times the image is refreshed per second. The vertical scanning frequency is generally not lower than 50 Hz, otherwise the image will have a flickering feeling.

RGB resolution refers to the highest pixel that the projector can pass when connected to RGB resolution video signal, such as resolution of 1024×768, indicating horizontal resolution of 1024, vertical resolution of 768, RGB resolution and horizontal scanning frequency. The vertical scanning frequency and video bandwidth are all related.
Video resolution refers to the highest resolution of the projector when displaying composite video. Here, it is necessary to analyze the relationship between the video band, the horizontal scanning frequency, the vertical scanning frequency and the RGB resolution: first, look at the relationship between the horizontal scanning frequency and the vertical scanning frequency.
In projector indicators, resolution is a confusing concept, often given on projector specifications. Horizontal scanning frequency = A × vertical scanning frequency × vertical resolution.
In the formula, A is a constant, about 1.2, and the vertical scanning frequency is generally not lower than 50 Hz. In order to ensure a good visual effect, it is desirable that the vertical scanning frequency is higher. In order to improve the image quality, the vertical resolution is also increased. These require a corresponding increase in the horizontal scanning frequency.
It can be seen that the horizontal scanning frequency is an important technical indicator of the projector. For example, when the scanning frequency is 70 Hz and the vertical resolution is 768, the line frequency is 64.5.
Focusing performance of CRT tube
The smallest unit of graphics is pixels. The smaller the pixel, the higher the graphics resolution. In a CRT tube, the minimum pixel is determined by the focusing performance, which is the number of minimum pixels. The focus mechanism of the projector of CRT tube is electrostatic focusing , magnetic focusing and electromagnetic composite focusing. Among them, electromagnetic composite focusing is more advanced, which has the advantages of good focusing performance, especially defocusing under high brightness conditions, and high focusing precision. Sub-area focusing, edge focusing, and four-corner focusing can be performed so that every point on the screen is clear.
Strictly prevent strong collisions, crushes and vibrations.
Because the strong earthquake can cause the displacement of the liquid crystal film, affecting the convergence of the three LCDs during the projection, the phenomenon that the RGB colors do not coincide, and the lens in the optical system, the mirror will also be deformed or damaged, affecting the image projection effect, and the zoom The lens will damage the track under impact, causing the lens to become stuck, and even the lens may not be used.
