How MCU Drives LCD Screen and Design Considerations

With the advancement of technology, beauty devices have made great progress, especially the introduction of 3.97-inch IPS screens. 480*800 resolution, 1000 contrast, support for RGB and MIPI interfaces, high-definition and delicate full-viewing angle, high color saturation and many other advantages, and the compact size of these screens makes handheld devices easy to carry around, while IPS technology gives users a clearer viewing experience. In this article, we explore the various applications of this screen in beauty devices.

Conventional 5 inch display screens cannot be seen clearly under strong outdoor sunlight unless they have a brightness of 2000 lumens. To achieve this brightness, the number of high-brightness LED lights needs to be increased, which will increase power consumption and reduce battery life. Our company has successfully mass-produced a semi-transparent and semi-reflective 5 inch screen with a resolution of 800*480 and an RGB interface. It can display clearly in the sun without turning on the LED light, which reduces the power consumption of the machine and is the first choice for many outdoor electronic devices.

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.

LCD screen itself has problems. If it is indeed the screen itself that is at fault after testing with relevant instruments, in addition to replacing a new LCD screen, the device-related software should be debugged and optimized so that the screen can work with the motherboard's CPU. The best way is to increase the OSC frequency of the IC and see how the LCD screen flickers. Of course, if the TFT LCD screen has separate row and column drivers, you can also adjust it by setting the driver chip.
