China 2.4 inch Sunlight-readable display MCU/SPI Manufacturers, Suppliers, Factory

As the name suggests, the liquid crystal display (LCD) panel uses a liquid crystal to turn pixels on and off to display specific colors.

At present, the touch technologies applied to products mainly include infrared, resistive, capacitive, surface acoustic wave, optical image, image recognition, panel induction, electromagnetic, light spot, and ultrasonic. The following is an analysis of the advantages and disadvantages of various touch technologies.

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.

First of all, the advantage of incell LCD screens is that they are thinner and lighter than traditional TFT displays because they integrate the touch sensor and display layer into a single layer. Traditional TFT LCD screens require external mounting to fit the touch screen, which increases the thickness. In addition, the touch screen also requires a separate design of a cable, which will occupy the space inside the machine. Incell LCD screens only need to be attached to a layer of glass cover to form a complete LCD touch screen assembly, which makes them ideal for portable devices such as smartphones and tablets. The reduction in thickness and weight makes the design more compact and stylish, which is very important for the trend of thinner and more portable devices.
