China 3.5 inch tft lcd 320*480 RGB/SPI Manufacturers, Suppliers, Factory

with a resolution of 1200*1920, a MIPI interface vertical screen, a brightness of 1500 lumens, which is clearly visible under strong outdoor light, and a contrast ratio of 1200.

IPS is the abbreviation of In-Plane Switching in English. The English meaning is in-plane switching hard screen technology, commonly known as "hard screen". It is the most advanced LCD panel technology in the world. Like wearing glasses. Generally, more mainstream mobile phones will use IPS screens, which have excellent display effects, so it has become one of the major selling points of many mobile phones.

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 choice of horizontal or vertical screens should take into account the user's usage habits and the application scenarios of the device. For example, mobile phones are usually used more vertically, but some videos or games may require horizontal screens. Shenzhen Hongjia specializes in the production of 1.14-inch to 10.1-inch display screens and matching touch screens. We have a relatively complete range of horizontal and vertical screen sizes, high and low resolution options, many standard interfaces, and also accept customer customization services.

Shenzhen Hongjia Technology has successfully mass-produced the 4.45-inch TFT LCD screen, model HJ4450-01. This 4.45-inch horizontal screen LCD features IPS full viewing angle, 1920*1080 resolution, a MIPI interface, and a high refresh rate of 120Hz.

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).
