LED Display Grayscale Control Chip

The LED Display Grayscale Control Chip is used for display data, to convert the received 8-bitLED display data into 12-bit output pulses

The LED Display Grayscale Control Chip is used for display data, to convert the received 8-bit (8-bit) LED display data into 12-bit (12-bit) output pulses, so that the display screen is based on achieving 4096-level gray-scale control, ensuring the LED display has non-line, 256 visual gray scales to achieve the full true color visual effect and can solve the system complexity caused by a large amount of data transmission in the digital display system.


1. Simplicity: Since the most complex data conversion part of the system is implemented in the form of the internal logic of the chip, the system becomes very simple.
2. Ease maintenance: It is the ease of maintenance of the system that is directly related to simplicity. Since the complicated control part is eliminated, system maintenance becomes a job that can be completed by junior technicians, which reduces the overall Maintenance costs and customer satisfaction.
3. High reliability: The simplicity of the system control part further brings the high reliability of the system. This is mainly because the integrated chip technology has several times more stability than the discrete device technology.
4. Cost-effective: FPGA system with vivid and natural image display and equivalent display control effect
5. Unitized and Structured Design: Consistent with the current development direction of the industry, the large-size led display screen system adopts a unitized design on the screen structure, and the system connection is intuitive and simple, which not only ensures that the size of the display screen can be adjusted according to the need for splicing. , And make the installation, commissioning and maintenance of the system extremely easy, thereby minimizing the invisible failure rate of the display screen system.
6. Industrial reliability design: The system adopts unitized design, which replaces a large number of discrete devices in the traditional design, and greatly improves the reliability and stability of the system. The complete system of project composition includes: data sources, transmission equipment, data processing, data distribution and software management tools, making the construction of LeD displays simple and standardized. The technology has been continuously developed and improved in the practical application process and has become the most mature, stable, and easy-to-implement system solution.
Equivalent to the CRT display, Tthe most important performance indicator of LED display is the grayscale (also called as brightness level) whici is achieved for each primary color (red, green, blue). The current international LED display standard is to require that each primary color achieve visual 256 gray levels. The built-in processing logic of the special grayscale control chip can output 4096 levels of grayscale, and select the 256-level grayscale output matched with the CRT display, so that the overall image effect is clearer, more realistic, and more appealing.
The other two performance indicators of LED display are its resolution and refresh rate. Due to the characteristics and requirements of the LED display itself, traditional solutions often have to lose one, or two, of standards as a cost to get another indicator. Since the data output per second per pin of the chip reaches 1 trillion, far exceeding the data output capacity of the traditional solution, the problem is fundamentally solved. The full-color system can support 1024 X 768 resolution and a higher screen refresh rate at the same time, far exceeding the performance indicators of traditional solutions, so that the display screen is stable, no flicker, no tail.
