What is the workflow of the LCD module?

Each pixel of an LCD module usually consists of a layer of molecules arranged between two transparent electrodes (usually made of indium tin oxide (ITO)) and two polarizing filters (parallel and perpendicular polarizers), which The transmission axes are (in most cases) perpendicular to each other. If there is no liquid crystal between the polarizing filters, light passing through the first filter will be blocked by the second (crossed) polarizer. Before an electric field is applied, the orientation of the liquid crystal molecules is determined by the alignment of the electrode surfaces. In a twisted nematic (TN) device, the surfaces of the two electrodes are aligned perpendicular to each other so that the molecules arrange themselves in a helical structure or twist. This causes a rotation in the polarization of the incident light, and the device appears gray. If the applied voltage is large enough, the liquid crystal molecules in the center of the layer are almost completely untwisted, and the polarization of incident light does not rotate as it passes through the liquid crystal layer. This light will then be polarized primarily perpendicular to the second filter, and thus blocked, and the pixel will appear black. By controlling the voltage applied to the liquid crystal layer of each pixel, different amounts of light can be allowed to pass through, making up different gray levels.

What is the screen display principle of the LCD module?

The picture display speed that people can accept is generally 24 frames per second, which is also the origin of the movie playback speed of 24 frames per second. If the display speed is lower than this standard, people will obviously feel the pause and discomfort of the picture. Calculated according to this index, the display time of each picture needs to be less than 40ms. In this way, for the LCD module, the response time of 40ms becomes a hurdle, and the display with a response time lower than 40ms will have obvious "smearing" or "afterimage" phenomenon, which makes people feel chaotic. If you want the image to be smooth, you need to achieve a speed of 60 frames per second.

What is the working physical principle of LCD module?

LCMs use color filters to generate red, green and blue sub-pixels. LCD color filters are fabricated by photolithography on large glass plates, which are then bonded to other glass plates containing TFT arrays, spacers and liquid crystals to form several color LCDs, which are then cut from each other and laminated with polarizers. Use red, green, blue and black photoresist.
