. Internally generated photons emitted to the outside of the chip can not be fully and finally into heat led electronic display, which is the main part, because this is called an external quantum efficiency of only about 30% Changyang led electronic display, most of them converted to heat a. As previously mentioned, although incandescent light efficiency is very low, only 15lm / W or so, but it almost all the electrical energy into light energy and radiate out, because most of the radiation is infrared, so low light efficiency , but it eliminates the problem of heat dissipation. Response time refers to the speed of each pixel LCD display of the input signal response of Xiangfan led electronic display, this value is the smaller the better, of course. If the response time is too long, it is possible to make the LCD monitor when displaying moving images, a tail shadow dragging feeling. Generally LCD response time between 5 ~ 10ms Icheon led electronic display products and brands, generally reached 5ms response time following basic avoid dragging tail shadow problems.
