Secondly, due to the Chinese government is actively promoting the industrialization of LED. 2003 established the National Leading Group of semiconductor lighting inter-ministerial coordination, launched the "National Semiconductor Lighting Project." National "863" followed by the relevant rate is due to the Chinese government to actively promote the LED industrialization. 2003 established the National Leading Group of semiconductor lighting inter-ministerial coordination, launched the "National Semiconductor Lighting Project." "863" plan for the relevant enterprises and research institutions have invested funds · Yidu corresponding LED display manufacturers to support basic research and technology industry and research institutions have invested the appropriate funds to support basic research and technology brightness : General Settings 60-80. Too bright easily cause eye fatigue, but also the use of phosphor premature aging. Contrast: generally set at 80-100. Refresh rate: If less than 70HZ, will feel flashes, set the computer's refresh rate increase. That field frequency refresh rate display manufacturers, the number of times per second the screen repeatedly drawn Zhijiang LED display manufacturers in HZ units. The higher the refresh rate, the more stable the Zigui screen display LED display manufacturer, flashes smaller. Most people's eyes for 75HZ refresh rate above the basic feel flicker, 85HZ above is no flashes, so VESA International Association 85HZ video for flicker-free progressive scan formulate standards. Ordinary color TV refresh rate is only 50HZ, computer output to the monitor's refresh rate is the lowest 60HZ, 85HZ or 75HZ is recommended refresh rate. Do not limit the display refresh rate is set at the highest grade should be slightly lower than its highest refresh rate. Because when the monitor is working at the limit state, prone to aging and damage the circuit elements.
