China 2.8 inch tft touch screen ST7789 50PIN Manufacturers, Suppliers, Factory

The causes of flickering streaks on LCD screens involve multiple factors, potentially related to hardware component anomalies, signal transmission issues, or external interference

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.

The 3.2inch IPS display is widely used in various electronic devices because of its high resolution, high brightness, and versatility. In this article, we will explore the different applications of the 3.2inch 320*480 resolution high brightness IPS display in the electronics industry.

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).

5-inch square LCD screen with a resolution of 720*720, supporting 2/3/4 channels via a MIPI interface, using the JD9365 driver IC, and incorporating INCELL technology for the touchscreen. The 5-inch square screen module is relatively thin, and only the cover glass is needed to form a complete touchscreen assembly. This product is widely used in electronic devices.

7-inch TFT landscape screens typically have a 1024*600 resolution and a 4-channel MIPI interface. 2-channel LCD screens are rare, and those integrating the capacitive touchscreen cable with the LCD screen cable are even rarer, increasing the workload for hardware engineers. Shenzhen Hongjia Technology engineers have successfully mass-produced 7-inch IPS landscape screens with a 1024*600 resolution, a 2-channel MIPI interface, and a capacitive touchscreen. The 24-PIN connector integrates the touchscreen and display signals, with a single cable interface for easier customer design
