Basic ideas of LCD screen maintenance in Shenzhen
Basic ideas of LCD} maintenance in Shenzhen 1. The whole display device is dead This is a relatively simple fault. Generally, there are two kinds of power supplies inside the LCD extension and outside the equipment. Those outside the equipment are more common. No matter what kind of power supply, its structure is much simpler than the power supply of CRT display screen. The vulnerable parts are generally some small components, such as fuse tube, input inductor, switch tube, zener diode and so on.

Why is the 10.1-inch LCD so popular?
With the rapid development of the times and the continuous progress of science and technology, if any industry has developed quite rapidly in recent years, there is no need to think about it. There must be the name of the industrial industry. Behind the vigorous development of the industrial industry, it is inseparable from the shadow of 10.1-inch LCD screen.

Yuhua micro: basic structure principle of capaciti
The basic structure of the capacitive touch screen is: the substrate is a single-layer plexiglass, a layer of transparent conductive film is uniformly forged on the inner and outer surfaces of the plexiglass, and a long and narrow electrode is tapered on the four corners of the transparent conductive film on the outer surface. Its working principle is: when the finger touches the capacitive touch screen, the high-frequency signal is connected on the working surface. At this time, the finger forms a coupling capacitance with the working surface of the touch screen, which is equivalent to a conductor. Because there is a high-frequency signal on the working surface, when the finger touches, it sucks a small current at the touch point, which flows out from the electrodes at the four corners of the touch screen respectively, The current flowing through the four electrodes is proportional to the linear distance from the finger to the four corners. The controller can obtain the coordinate value of the contact point through the calculation of the proportion of the four currents.
