LCM

What is LCM and what does LCM mean?
LCM (LCD module) is an LCD display module and a liquid crystal module. Refers to the assembly of liquid crystal display devices, connectors, peripheral circuits for control and driving, PCB circuit boards, backlights, and structural components.

The nominal Brightness of the LCD Monitor depends on the nominal brightness and contrast of the panel used. For LCD Monitor products, LCD is required to have a wide Viewing Angle, because they usually need to watch video at a fixed distance. And higher brightness and contrast.

For PC monitors, brightness and contrast can be displayed on 200cd / m2 or 300:1, but the brightness and contrast of monitors usually need to be higher than 300cd / m2 and 450:1. Its requirements. Therefore, LCD monitors usually use panel indicators higher than PC monitors. In order to improve the brightness of the display, some manufacturers have modified panel's backlight, increased the number of lights in the backlight to improve the luminous efficiency of the backlight, thus improving the brightness of panel. However, brightness / contrast does not have to be as high as possible. Image quality is not only related to brightness / contrast: image clarity, color restoration, SNR and other characteristics are also very important.

As with CRT monitor adjustments, the brightness / contrast will not be as high as possible when adjusting the LCD monitor. The normal adjustment effect is to restore the display from black to white or from white to black. That is to say, it is observed that the excessive image in the change of light and shade is a uniform transition, and whether the image is bright without glare, clear without hard.
