â‘?non-linear adjustment of output, is more suitable for human eyes to watch;
â‘?100 Screen brightness control;
â‘?constant current drive;
â‘?cell plate of red, green and blue light were adjusted to eliminate the mosaic.

(4) LED display with indoor full color system: the chip display data in addition to completing the allocation of tasks, their identity is to receive 8-bit (8 bit) display data into 12-bit PWM output pulse, so that the display implement 4096 (12bit) gray control to ensure the visual gray scale nonlinear realization of 256 to achieve full-color visual effects, can be a fundamental solution to the digital display system because the data transmission caused by excessive complexity of the systems. has the following characteristics:

â‘?simplicity because the system part of the most complex data conversion to the chip internal logic are realized in the form, the system becomes very simple.

â‘?ease of maintenance and simplicity of the system is directly related to ease of maintenance, as part of eliminating the need for complex control, system maintenance becomes a technical staff from the primary to complete the work, which not only reduces the overall maintenance costs , but also improves customer satisfaction.

â‘?high reliability part of the simple control system to further bring the system's high reliability, which is mainly due to separation compared to integrated chip technology has several times the stability of the device technology.

â‘?cost-effective system to achieve the most reliable performance of 4096 gray-screen color control, image display realistic, natural, display control to achieve the same effect.

â‘?modular, structural design and direction of the current development of the industry consistent with a large led screen display system in the body structure using modular design, the system intuitive and easy connection, not only to ensure that the display body size can be adjusted according to need stitching, And the system's installation, commissioning and maintenance has become very easy to monitor the system to minimize the failure rate is not visible.

â‘?industrial design system reliability, modular design, replacing the traditional design of a large number of separation devices, the system greatly improved the reliability and stability.

â‘?comprehensive plan that contains the data source component systems, transmission equipment, data processing, data distribution and software management tools to enable the construction of LED display into a simple standardization. The technology in practice continue to develop and perfect the process has become a the most mature, stable, easy to implement system solutions.

â‘?equivalent CRT display LED display most of the core indicators of performance for each primary color (red, green, blue) that is achieved by the gray level of brightness, the display of the current international standard is required for each color to achieve Vision 256 Gray. special gray control processing logic chip 4096 can be output to gray, and from the phase selection and fitting of CRT displays 256-level grayscale output, and the overall picture was more clear, realistic, full of infectious .

�high resolution and high refresh rate in addition to gray scale, the display of the other two performance indicators are the resolution and refresh rate. As LED panel their own characteristics and requirements, the traditional solution to the loss of which often one or two criteria as another indicator of the price increase. As chips per second per pin data output reached 1 trillion, far more than the traditional program data output capability, so that the fundamental problem be resolved. The full-color system can support both screen resolution of 1024 × 768 screen and high refresh rate in addition to gray scale, the display of the other two performance indicators are the resolution and refresh rate. As LED screen their own characteristics and requirements, the traditional solution to the loss of which often one or two criteria as another indicator of the price increase. As chips per second per pin data output reached 1 trillion, far more than the traditional program data output capability, so that the fundamental problem be resolved. The full-color system can support both screen resolution of 1024 × 768 screen and up to 300Hz refresh rate, far exceeding the performance of traditional solutions to enable the display stable, no flicker, no tail.
