Abstract

The embodiment of the invention provides a driving circuit. The driving circuit comprises a switching control sub-circuit and a voltage processing sub-circuit, wherein the switching control sub-circuit receives a mode switching instruction, and the switching control sub-circuit controls the voltage processing sub-circuit to output driving voltage according to the mode switching instruction. In the mode switching process, the switching control sub-circuit controls the voltage processing sub-circuit to output transition voltage according to the mode switching instruction at the moment T1, liquid crystal molecules in a liquid crystal device deflect, and the liquid crystal molecules deflect to a deflection angle range corresponding to the transition voltage; and the switching control sub-circuit controls the voltage processing sub-circuit to output driving voltage required by driving the liquid crystal device to operate according to the mode switching instruction at the moment T2. In the mode switching process, the transition voltage is applied to the liquid crystal device, the liquid crystal molecules deflect, and then the driving voltage is applied at the next moment, so that the mode switching time of the liquid crystal device is shortened, and the display effect of the liquid crystal device is improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular, to a driving circuit, a liquid crystal lens including the driving circuit, a stereoscopic display device including the driving circuit, and a liquid crystal microlens including the driving circuit. Background technique [0002] The liquid crystal device made of liquid crystal molecules can realize the switching of different working modes according to the needs of use. For example, the liquid crystal lens can switch between 2D and 3D display modes by changing the voltage applied to the liquid crystal lens; another example is the liquid crystal microlens, which can switch the focal length by changing the voltage applied to the liquid crystal microlens. Although the working mode of the liquid crystal device can be changed by changing the voltage, however, during the mode switching process, when the liquid crystal device is directly switched from one working mode to another, d...
