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.

Another advantage of using a 3.4-inch round TFT screen is that it is compatible with both RGB and MIPI interfaces. RGB interfaces are commonly used in consumer electronics, while MIPI interfaces are popular in mobile devices. Shenzhen Hongjia Technology produces 3.4-inch round TFT screens that can support RGB interface support 16/18/24 bits; also supports MIPI interface support 2/3/4 channels. This compatibility allows for easy integration with a variety of products, making it a versatile choice for many different applications.

In short, for small-sized LCD screens, QSPI is a better choice: through pin multiplexing and queue mechanism, while maintaining sufficient transmission rate, PCB design and master control resource usage are greatly simplified, which is especially suitable for scenarios that require dynamic display and limited space. SPI is only applicable to extreme cases where the driver IC does not support QSPI or has extremely simple functions. When actually selecting, it is necessary to first confirm the interface specifications of the screen driver IC (some screens support both SPI and QSPI, which can be switched by configuring pins).

Are you facing a black screen on your LCD display? This problem can be frustrating, and it can be challenging to identify the root cause and resolve it. In this article, we will discuss some common reasons for this problem and share some tips on how to fix it.

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.
