MK-H24I2005B is a 2.4inch uart tft display module,driver IC SERIAL COMM, FPC and a backlight unit. The module display area contains 240x320 pixels, This tft module accords with RoHS environmental criterion. The logic power supply voltage range is 1.8V to 3.3V. 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.

The main component of the TFT color screen module is the lcd display module, which is a serial port lcd screen, which can communicate with the main control board through the serial port, so as to display fonts and graphics of different sizes and colors. The interface of this module is marked in blue/gray color, indicating that it is a dual digital interface, which needs to be connected to the interface marked in blue or gray on the main board.

User Interface easily- just connect the PC and the UART TFT-LCD module through the UART port, and create everything with our software.

By the function of Simulation, you learn how it works on the display.

1. Basic specifications

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.

2. Drawing Confirmation

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.

3. Sample making

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.

4. Sample delivery

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.

5. Technical service

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.

How do you guarantee the quality?

We have passed SGS,ISO9001, ISO14001 certification. We carry out strict quality control checks and every tft lcd display is 100% inspected by at least 5 inspection positions before entering the warehouse.

Do you have MOQ restrictions? Can I also communicate the price?
