Liquid crystal is a special kind of liquid crystal. It can flow like a liquid and has certain optical properties of a crystal. Liquid crystal was discovered by Austrian botanist Reinitzer in 1888. It is an organic compound with a regular molecular arrangement between solid and liquid. Changes in electromagnetic fields are very sensitive.

Under the action of an electric field, the arrangement of liquid crystal molecules changes, which affects its optical properties. This phenomenon is called the electro-optic effect.

How to determine the display of the LCD display

Increase the gray level of full color LED display

The gray level of the LED display refers to the number of brightness levels that can be distinguished from the darkest to the brightest in the brightness of a single primary color. The higher the gray level of a full-color LED display, the richer the color and the brighter the color; otherwise The display color is single and the change is simple. Increasing the gray level can greatly enhance the color depth, which makes the display level of the image color increase geometrically.

Now many full-color LED display manufacturers can make the display's gray level from 14bit to 16bit, so that the image hierarchy can distinguish details and display effects more delicate and realistic, gorgeous and colorful.

Improve the contrast of full color LED display

Contrast is one of the key factors affecting the visual effect. Generally speaking, the higher the contrast, the clearer and more vivid the image, and the brighter and more vivid the color. High contrast is very helpful for image clarity, detail performance, and grayscale performance.

Full color LED display combined with video processor

LED video processors can use advanced algorithms to modify signals with poor image quality, and perform a series of processing such as de-interlacing, edge sharpening, and motion compensation to enhance image display details and improve screen display quality. The video processor image scaling processing algorithm is used to ensure that the video image is scaled to maintain the image's sharpness and gray level to the greatest extent.

Reduce the dot pitch of full color LED display

Narrowing the dot pitch of the full-color LED display can improve the sharpness of the display screen, because the smaller the dot pitch, the higher the pixel density per unit area of the full-color LED display, the more details can be displayed, and the screen display The more delicate and realistic it is.
