Backlight source and backlight technology of LCD display


The so-called LCD display backlight culture refers to the design of a specific light source so that the LCD display whiteboard can display different image content under certain light conditions. My country's research on liquid crystal displays started late, but with the continuous improvement of visual requirements, the development of LCD display whiteboard has also been greatly improved. At present, most of the LED displays on the market are directly produced by manufacturers, many of which are imported, some are imported by manufacturers from abroad, and some are independently developed in China. All of these show that the development of backlight culture has become a trend, and it will also bring a better future and prospects to society.

Types of Backlights


There are many types of LCD display backlights on the market, the main ones are:

① Backlight tube, its function is to convert the light signal into an electrical signal, and then the control of the light can be realized through the processing of the circuit. It has high value and practicality, but because it is expensive, most manufacturers will not choose it. ②Polarized transmissive reflective transmissive mirror, when the light passes through the lens, the light beam is divided into two beams, which are two different parallel beams in the vertical direction, and a rotating angle is generated at the same time, which is called "oblique entry". Then, the motion state of the light beam can be changed, so that the LCD display whiteboard can achieve the best imaging effect.



Development means of backlight


At present, the main way of using the screen of the LCD display whiteboard is through the backlight source, and the development methods of the backlight source in the market are as follows.

① Use the method of mechanical manufacturing to complete. The price of this type of equipment is relatively low, and the processing technology is relatively complex, so its application scope is limited.

②Use the electron beam method. The working principle of this type of machine is to place the position of the camera in the designated place and then project the captured picture to the computer, and finally, the required brightness information can be obtained after being processed by the computer. This not only saves the workforce but also reduces production costs and time.

③Weld by arc welding. The advantages of this type of instrument are its small size, lightweight, strong shock resistance, high-temperature resistance, and electromagnetic interference resistance.




The business model of backlight


For the business model of LCD display whiteboard backlight, there are mainly the following methods.

①Direct projection: place a specific electronic component on the LCD display of the backlight, and then install it in the required position. The advantage of this is that it allows consumers to watch without touching the product, and it also saves time.

②Projection type: By combining the luminous flux of different LEDs, the lighting effect of the target object can be achieved.

③Hybrid: The simultaneous combination of two or more light sources will generate a new visual stimulus, which is also one of the most common applications. It combines with traditional direct projection and projection to create better imaging results.

④ Adaptive array: LCD display whiteboard has the characteristics of small size, lightweight and low power consumption, so its production cost is low, so it has become the choice of more manufacturers.
