LCD segment LCD screen, or LCD segment LCD screen, is a type of liquid crystal product. However, in the LCD industry, it is generally called pattern LCD screen, pen segment LCD screen, and monochrome LCD screen. LCD screen and so on. With the development of the world, LCD liquid crystals have now been widely used in various industries, such as instrumentation, medical care, agricultural machinery, office equipment, home appliances, communications, banking, etc. So why do so many industries now choose segment code LCD screens? Yes, what are its advantages?
The main advantages of LCD segment code LCD screens are as follows:
1: Intuitive: There are pictures and numbers, and you can understand the meaning at a glance.
Two: Beautiful and elegant: Compared with the LED digital tube display, the product quality is higher.
3. Thin body, saving space: Compared with the relatively bulky CRT monitor, the LCD monitor only takes one-third of the space of the former.
Four: Saves power and does not generate high temperatures: It is a low-power product that does not get hot at all. Compared with CRT monitors, high temperatures are inevitable due to imaging technology.
Five: No radiation, good for health: LCD monitors are completely radiation-free, which is good news for people who work in front of computers all day long.
6: The picture is soft and does not hurt the eyes: Unlike CRT technology, the LCD screen will not flicker, which can reduce the damage to the eyes caused by the display and make the eyes less likely to fatigue.
You have completely dismantled it. You should also need a plastic frame and a back plate on the outside.
The white piece at the bottom is a reflective sheet, which controls the light to only go to the cell. Directional emission
The transparent resin plate is a light guide plate, which is responsible for turning the LED point light source into a surface light source
The top is a diffuser to make the light source more uniform
Above are two prism sheets, which concentrate the light source and improve the utilization of the light source.
The black one at the top is the key point. All the display depends on it. It is the cell. The structure inside is complicated. Let me explain it first. Post a picture.
CELL is mainly composed of array and CF, and there are polarizing plates on both sides. There are so many things in it that it would be endless to talk about. You can simply understand that these are Control the liquid crystal to transmit different colors of light to achieve the display effect.
That PCB board controls the entire circuit and video signal processing.
