Shenzhen Yuhua micro: what is the principle of LCD

Shenzhen Yuhua micro is a company specializing in research, development and production of LED application products, with a variety of product structures. Its LED display series include: rental products, billboards, overhead displays, highway signs, special-shaped color screens, stadium screens, vehicle screens, etc. it is widely used in all kinds of public places, such as commercial squares, government departments, stadiums, transportation facilities, financial units, factory workshops, conference rooms, stages, banquet halls and other public places, and occupies a dominant position in the domestic market.

What else is there about Shenzhen LCD? LCD is an active matrix liquid crystal display driven by thin film transistor (TFT). It mainly forms a picture by stimulating liquid crystal molecules to produce point, line and surface with backlight. TFT and SLCD belong to the category of LCD. The working principle of liquid crystal screen is: under the action of electric field, the arrangement direction of liquid crystal molecules is changed to change (modulate) the transmittance of external light source, complete the electro-optical conversion, and then use the different excitation of R, G and B primary color signals to complete the color reproduction in time domain and space domain through the red, green and blue primary color filter film.

LCD is an electronic display screen composed of LED dot matrix. It displays the timely conversion of text, animation, pictures, videos and other contents through the replacement screen of traffic signal beads, and displays components through the module structure. Including power supply module, display system and control system. The display is composed of LED light dot matrix, and the screen emits light; The control system is the light off condition in the control area to realize the conversion of the content displayed on the screen; The power supply system converts the input voltage and current to meet the needs of the display screen.

Liquid crystal display, or LCD (liquid crystal display), is a flat-panel ultra-thin display device, which is composed of a certain amount of color or black-and-white pixels, which are placed in front of the light source or reflective surface. The power consumption of LCD is very low, so it is favored by engineers and is suitable for electronic devices using batteries. Its main principle is to stimulate liquid crystal molecules with current to produce points, lines and surfaces to cooperate with the backlight to form an image.

The 256 level gray algorithm is realized with the LED full-color screen. The color transformation "point by point dynamic compensation technology" is adopted in the design, which is suitable for the full-color LED display screen made of pure green or yellow green tube. This technology enables the color of the LED display screen to maintain the brilliance of the original image. The frequency of scanning field is above 240Hz, and the picture is stable without flicker. In practical application, the camera is used to capture the display screen. The image observed by the camera is clear and there is no synchronous scroll bar. If there is TV transmission on site, the display screen will not affect the image quality of the broadcast picture.
