With the increasing popularity of the Internet, all kinds of communication devices are becoming more and more popular among consumers, which leads to a sharp increase in the demand for data transmission. In addition, digital TV, high-definition TV, and color images all require higher bandwidth. Therefore, system design engineers must rely on analog technology to design circuit systems and support data transmission. Low-voltage differential signaling (LVDS for short) is one such analog technology that engineers can use to design mixed-signal systems. LVDS uses high-speed analog circuit technology to ensure that copper wires can support data transmission above gigabits.

​An LCD display module is an electronic component used for displaying characters, symbols, and graphics in a clear, easy-to-read format. It typically consists of a liquid crystal display (LCD) panel, a driver circuit board, and other supporting components, such as backlighting and a controller chip.

Overheating of the LCD screen may accelerate component aging (such as shortening the screen lifespan). In severe cases, it may cause deformation of the plastic casing, damage to the circuit insulation, and even risk fire. If abnormal overheating cannot be alleviated by the above methods, it is recommended to immediately discontinue use and send the device for repair.

Some customers are still not very clear about the resolution of the display screen. We will explain it here. The resolution of the LCD screen refers to the number of pixels of the LCD screen, that is, the number of dot matrix, which is usually the number of pixels in the horizontal direction multiplied by the number of pixels in the vertical direction. Under the same LCD screen size, the higher the resolution dot matrix, the clearer and more delicate the display image effect is.

TFT liquid crystal display screen is a display screen widely used in various electronic devices, with high resolution, high brightness, and high contrast. With the continuous development of technology, the application of wide color gamut technology is becoming increasingly widespread, which can greatly improve the display effect of display screens and make them present more realistic colors.
