China 3.4 inch Square IPS High Brightness screen Manufacturers, Suppliers, Factory

Display and touch screen technology is becoming more and more mature, and there are many suppliers in the market. The production process, R&D capabilities and product reliability of different suppliers vary greatly. How to choose a reliable supplier is very important for buyers, which can reduce the troubles of many buyers and improve the quality of products.

Ordinary LCD screens use CCFL light sources, that is, cold-cathode fluorescent lamps (similar to the scanning lamps in the copy), with one on each side of the screen and a backlight on the back of the display, which is composed of fluorescent substances. The light sources on both sides can be evenly distributed on the back of the entire screen, so that the entire screen can be evenly illuminated. However, due to technical limitations, the brightness of such a display is not completely uniform, but it is difficult to find it. At the same time, the lamp also has a certain lifespan, and it will turn yellow after a long time.

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.

Generally speaking, the main reasons may include: reducing the number of pins to accommodate a small package size; reducing the need for host control resources (GPIO, parallel interface); simplifying hardware design (PCB layout, level conversion); the small amount of initial configuration data, which is sufficient and easy to implement with SPI; and the driver IC design supporting serial interface configuration.
