H35J3501 is a 3.5 inch tft lcd display MCU interface with a resolution of 320×480 pixels, a driver IC ST7796S, a brightness of up to 320-800cd/m2 (typical value), and supports SPI interface, SPI 3 wire and 4 wire serial ports, Standard models and customized RGB interfaces and MCU 8 bit or 16 bit interfaces can be provided. There are 2 kinds of TN screen viewing angles and IPS screen. The logic power supply voltage range is 2.4V to 3.3V. Touch can choose resistive touch screen or capacitive touch screen For touch screen control, we have two connection methods: welded cable FPC and plug-in cable, which can be adjusted with a polarizer to have a wider viewing angle, high definition high-brightness wide viewing angle. It can operate in temperatures from -20°C to +70°C and has a storage temperature range of -30°C to +80°C. The quality of Hongcai Lcd display is higher than the industry standard, batches of products have no color cast, color and brightness are consistent, industrial and consumer grade production process requirements, stable quality, continuous supply, worry free after sales service and technical support.

We can provide 5pcs tft display for free.

The required TFT Lcd screen size, resolution, communication interface type between motherboard and TFT screen, display viewing angle, touch type selection, external dimensions, structural design, voltage, connection method of FPC cable, or specified Hongcai model.

According to the needs of communication and verification, as well as standard or customized materials, such as resistive touch or capacitive touch, wiring FPC or backlight, arrange the structural drawings of TFT Lcd display screens to customers for confirmation within 2-3 days.

The sample delivery time for standardized tft display is 2-3 days. For customized lcd display, samples are made according to the confirmed drawings. Sample production takes time. The sample delivery cycle of Lcd screens is generally 7-12 days. The cycle time is 18-21 days.

After the sample production is completed, it will be inspected according to the sample delivery process, and a series of structural and electrical performance tests, high and low temperature and thermal shock aging tests, vibration tests, salt spray tests, etc. will be arranged according to the quality control procedures, and tests will be carried out according to the requirements of different customers , Provide the actual test report of the tft display to ensure the reliable performance of the tft display.

After receiving the customer’s sample, we will provide the IC driver, the initialization code of the LCD screen, and the technical support will cooperate with the adjustment program to light up.


We conduct strict quality control checks, and 100% of each product passes through at least 5 inspection stations before delivery.

No strict MOQ limit. Small quantity orders are also welcome!

Yes. We are a 12 years production manufacturer.We can provide 600K-700K/PCS for one month.

We offer a 12 months warranty. If there is a problem, we will analyze the samples and provide a report with a short-term and long-term solution. If it is a problem with our product, we will replace it.

We already have agents in some regions and we are looking for more agents in certain regions.
