China 3.0 inch IPS High Brightness display 240*400 ST7793 Manufacturers, Suppliers, Factory

Many clients designing compact, slim-profile devices frequently inquire about small, elongated displays. Today, Mr. Huang—an engineer at Shenzhen Hongjia Technology—introduces a 1.47-inch bar-type display featuring a 172×320 resolution. This model supports both SPI and MCU interfaces, utilizes a 24-pin connection, includes a capacitive touch panel with an I2C interface, and is driven by the stable and reliable ST7789 IC. Below, Mr. Huang provides an analysis of why this 1.47-inch bar display is an excellent hardware choice for small-scale devices.

The LCD TE pin, defined as the "Tearing Effect," primarily serves a data synchronization function, converting analog signals captured by the camera into digital image signals. The host then transmits these digital image signals to the display, which can cause image tearing. To address this issue, the TE function was introduced, allowing a complete, tear-free image frame to be transmitted to the display. Screen clipping can often occur when using a portrait screen as a landscape screen if improperly configured. If the LCD screen has a TE interface, it is recommended to connect the TE pin.

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.

A common question customers encounter when designing capacitive touchscreens is this: which is ultimately more reliable and durable—G+G or GFF? Simply put, G+G and GFF represent two different material structures within the realm of capacitive touchscreens. Generally, G+G outperforms GFF in terms of performance and quality, while GFF holds distinct advantages regarding cost-effectiveness and suitability for mass production. To begin, it is essential to understand exactly what G+G and GFF entail.
