Explanation of brightness technical knowledge of high-brightness LCD screen (2)
The liquid crystal molecules allow the light to pass or block it to Display. Bring out the brightness of the picture. This process is controlled by an IC chip. Its principle is similar to the shutter in a camera, which can control the light flux. Camera products usually have a shutter behind the lens. When taking a picture, the shutter is opened to allow the object to be imaged on the film or sensor to form a photo. In addition, the LCD Panel emits light with balanced brightness from the backlight. After the light is shielded and controlled by the LCD Panel, the image is formed by the brightness of the light.
The light passing through the LCD Panel not only has two forms: light and dark, but also has various color levels from light to dark. In addition, when we watch a continuous animation, the standard requires 60 pictures per second, that is, switching between light and dark states 60 times per second. In order to express the accuracy of the picture, a sufficient number of pixels must be required, and the structure of the LCD Panel must also be fine enough.
