About the resolution of LCD

Resolution Resolution is a very important performance indicator. It refers to the number of points that can be displayed horizontally and vertically on the screen (lines and planes on the screen are composed of points). The higher the resolution, the more information can be included in the same screen. 480×800 resolution and 320×240 resolution are perfect display. Because there is little difference between the two, but the maximum resolution is not necessarily the most appropriate resolution. If 480×8000 LCD is used in 320×240 LCD, the display content will be smaller.   Visual area of LCD It refers to the part of the display area that can be used to display the image in practical application. The full size is actually the size of its frame and PCB board, and the part that can be used to display images does not reach this size at all, because the frame takes up some space. Generally speaking, the area of 4-inch 480×800 LCD is 51.84×86.4mm, and that of 3.5-inch 320×240 LCD is 70.08×52.56mm. But for LCD, the size of area is basically the size of the visible area, and the space occupied by the frame is relatively small. The 4-inch 480×800 LCD has a display area of 51.84 * 86.4mm.So choose LCD screen, choose suitable for your own equipment.   Reaction speed The unit of time used to measure reaction speed is millisecond (ms), which is the time required for a pixel to go from light to dark and from dark to light.

LCD brightness and LCD backlight requirements

LCD brightness Brightness represents the amount of brightness of a picture per unit area. Specifically, the density of the amount of light passing through the normal direction of the screen. The unit is [CD / m2] or nit(1 nit = CD / m2).Brightness depends on the amount of light passing through the LCD and color film, and the brightness of the backlight.   LCD backlight requirements: The liquid crystal should have good transmittance; light weight; It should be thin and not easy to damage; The area light source with uniform brightness is the best; Low cost; The light color is pleasing to the eye, the primary color is rich, and the brightness can be adjusted; Low power consumption and easy power supply

LCD splicing screen is often damaged by dust

At present, LCD splicing screens are becoming more and more mature in application industries such as indoor high-end command and control centers, dispatch centers, and monitoring centers. We all know that dust is harmful to the human body, but you certainly did not expect that dust will also do the same to LCD splicing screens. As an electronic product with extremely high technological content, LCD splicing has a great impact on it due to dust. The LCD splicing screen movement uses many optical components, and it is precisely the dust that damages the optical components the most. Contrast refers to the maximum brightness value that the large screen display unit can output divided by the darkest brightness value. When in a dark scene, the dust on the optical components will reflect stray light and project the light that should not be projected from the lens. The brightness of the dark part. Similarly, some light in the bright part will be blocked by dust, reducing the amount of light reflection and transmission, and reducing the brightness value of the bright part, the contrast will naturally decrease in the past. The color wheel of the LCD splicing screen is the main accessory for color processing, including a high-speed motor, which rotates at about 7200 revolutions per minute. If a lot of dust is attached to the periphery of the color wheel, it will affect the rolling of the color wheel, resulting in a decrease or instability of the color wheel speed, which
