Leasing LED display must to meet the requirements of the television industry
TV is the largest mainstream media, LED screen gives the first impression is actually as a large outdoor TV, in television shows, sports games and various exhibitions occupy an important position.
● Grayscale normal shooting, no flicker, is a must meet the lease screen requirements
Rental screen usually have television camera applications, usually speaking, the camera shutter speed of 1 / 50s or 1 / 60s, while the rental LED display refresh rate is generally designed to be relatively high, but also mainly consider the needs of television cameras (Although the camera uses a high-speed electronic shutter can be a thousandth of a second or faster, but the professional cameraman does not use this.Professional cameraman can combine slow shutter exposure to avoid flicker.The phone is usually a fixed aperture to iPhone4S For example, the aperture is 2.4, the daytime outdoor shooting shutter is 1 / 1,600s or so.Electronic shutter speed can be high, this shutter speed, the LED display, the difficulty is still relatively large).
● TV industry requires LED display to achieve good image quality and high refresh rate under the condition of low brightness
TV camera on the LED display low brightness display requirements. The current indoor LED display mainstream product brightness has reached 1,500 to 2,000nit, than the previous are usually 1,000nit up and down the times almost doubled. On the other hand, due to the low brightness adaptability of the camera, the brightness of the TV studio has been reduced, the typical illumination from about 800lux reduced to about 500lux, which shows the LED screen under the conditions of low brightness made a higher Requirements (LED displays with a maximum brightness of 2,000nit require sufficient gray levels and refresh rates at 200-300nit brightness), which requires adequate control of the LED display's control system and hardware configuration to meet both high Brightness and low brightness status.
