Problems solved by technology
[0005] However, when the display device is large, due to the impedance of the line itself and the overlap between the lines, the load of the light-emitting control signal will be heavy, and the instantaneous current of the light-emitting control signal will be relatively large at the moment of level conversion of the light-emitting control signal. (like Figure 7 shown in the I-En waveform)

The invention relates to a display device and a light emission control signal generation device and method. The generation device comprises a two-out-of-two multiplexer, a first operational amplifier,a second operational amplifier and a one-out-of-three multiplexer; the two-out-of-two multiplexer selects to output a first input signal from a first output end of the two-out-of-two multiplexer according to a first control signal, or selects to output a second input signal from a second output end of the two-out-of-two multiplexer according to the first control signal; the first operational amplifier receives the signal output from the first output end of the two-out-of-two multiplexer and outputs a first output signal; the second operational amplifier receives the signal output from the second output end of the two-out-of-two multiplexer and outputs a second output signal; and the one-out-of-three multiplexer receives the first output signal, an intermediate signal and the second outputsignal, and outputs one selected from the output signal, the intermediate signal and the second output signal according to the second control signal and outputs the selected signal as the light emission control signal. The light emission control signal can be provided for the display device.
Description
technical field [0001] The present disclosure relates to the field of display technologies, and in particular, to a light emission control signal generation device, a light emission control signal generation method, and a display device using the light emission control signal generation device. Background technique [0002] VR (Virtual Reality, Virtual Reality) technology uses computer simulation to generate a three-dimensional virtual world, providing users with simulations of vision, hearing, touch and other senses, making them feel like they are on the scene. In the process of using VR equipment, in order to reduce dizziness, it is necessary to reduce the delay effect of image output. At the same time, in order to allow the eyes to capture the correct image, it is also necessary to reduce the time from image output to the completion of the entire screen display, as well as the pixel receiving time. Response time from signal to completion of display. With the development ...
