Abstract

The invention provides a sample hold circuit, a discharge control method and a display device. The sample hold circuit comprises a sample hold unit and a control unit capable of providing an enable signal to the sample hold unit, wherein the input end of the sample hold unit is connected with a sampling input end; the sample hold circuit also comprises a discharge unit; the control unit comprises a discharge control module; the discharge control module is connected with the sample hold unit, and is used for outputting a discharge control signal according to the sampling input signal when the sample hold unit begins discharging; the discharge unit is connected with the output end of the sample hold unit and the discharge control module, and is used for controlling the sample hold unit to finish a discharge operation within preset time under control of the discharge control signal. The sample hold circuit is capable of rapidly finishing the discharge operation and rapidly making preparation for next sampling.

Description

technical field [0001] The invention relates to the technical field of sampling and holding, in particular to a sampling and holding circuit, a discharge control method and a display device. Background technique [0002] In naked eye 3D technology, due to the need for eye tracking and judging the position of the eyes to realize the change of the screen, the amount of data to be processed has increased significantly. In order to provide sufficient computing time, it is required to display the original operation to compress the computing time and improve efficiency. . Among them, it is a method to perform fast sample and hold to reduce the data acquisition time. [0003] Such as figure 1 As shown, the existing sample and hold circuit can be a sample and hold circuit built by a high-speed sample and hold chip 11 modeled as DS1843. In the figure, Vin and Vout are respectively the sampled input signal and the sample and hold circuit output signal, and SEN is the DS1843 The ena...
