TFT LCD display is one of the most common and widely used displays in the current market, it has excellent display effect, wide viewing angle, bright colors and other characteristics, widely used in computers, mobile phones, TVs and other various fields. How to develop and customize a TFT LCD display?
I. Preparations
1. Determine the purpose of use and demand: the purpose of use and demand is the key to the development of custom LCD. Because different application scenarios require different LCD displays , such as only monochrome display, or TFT display? What is the size and resolution of the display?
2. Selection of manufacturers: it is very important to choose a suitable manufacturer according to the needs, because different manufacturers’ price, quality, technical level are very different. It is recommended to choose a manufacturer with scale, high qualification, as well as more reliable technical level and quality.
3. Design circuit schematic: after selecting the panel and control chip, you need to draw the circuit schematic, which is a key in the development of the LCD display. Schematic diagrams need to mark the LCD panel and control chip pins, as well as other related circuit devices connected.
II. Sample production
1. Select panel and control chip: according to the design of the circuit schematic to select the appropriate LCD panel and control chip, which is a prerequisite for the production of prototype board.
2. Print the board layout: Before making the prototype board, you need to draw the board layout first. Board layout is the circuit schematic into the actual PCB circuit connection graphics, is the basis for the production of prototype board.
3. Production of prototypes: on the basis of the board layout diagram, the beginning of the production of LCD sample. The production process needs to pay attention to the label of component numbers and circuit connections to avoid connection errors.
4.Prototype testing: sample production is completed, you need to test, the testing has two main aspects: test whether the hardware is properly connected, test software to drive the hardware to carry out the correct function.
III. Integration and development
After connecting the tested sample and the control chip, we can start the integration and development, which mainly includes the following steps:
1. Software driver development: according to the specifications of the panel and the control chip, develop the software driver. Software driver is the core programme to control the hardware output display.
2. Function development: On the basis of the software driver, add the custom function of the target display. For example, show the company's LOGO on the display, show specific information on the display.
3. Sample debugging: sample debugging is the most critical part of the entire development process. In the debugging process, we need to carry out functional and performance testing to find and solve the existing problems and defects.
IV. Small batch trial production
After the integration and development are completed, small batch production is performed, which is a key in turning the developed display into an actual product. In small batch trial production, production of prototypes is required, and quality and performance tests are performed on the produced prototypes.
V. Mass production
After the small batch trial production is passed, the mass production can be carried out. During the production process, it is necessary to strictly follow the testing standards, and regularly maintain and repair the equipment of the production line.
All in all, developing and customizing a TFT LCD requires multiple steps from preparation, sample production, integration and development, small batch trial production to mass production. Mastering each step and operating in strict accordance with the standards will ensure the quality of the finished product and the improvement of production efficiency.
