Abstract

The invention discloses a liquid crystal lens plate and a display device, so that the light emitting direction of the display device can be controlled, thereby improving the light utilization rate and enriching the application occasions of the display device. The liquid crystal lens panel includes a first substrate, a second substrate, and a liquid crystal layer between the first substrate and the second substrate, wherein: the first substrate and the second substrate are provided with a first electrode and a second electrode forming an electric field, The second electrode includes a plurality of electrode units arranged in an array, and the electric field between the electrode units and the first electrode drives the liquid crystal layer to form a lens equivalent unit.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a liquid crystal lens plate and a display device. Background technique [0002] At present, common display devices are generally thin film transistor liquid crystal displays (Thin Film Transistor Liquid Crystal Display, TFT-LCD) or organic light-emitting diode displays (Organic Light-Emitting Diode, OLED), the light emitted by these display devices forms a spherically emitted light field, so , the display device has a wide range of lighting viewing angles in space. [0003] However, just because the display device has a wide light-emitting viewing angle in space, only a small part of the light energy is received by human eyes, and the utilization rate of light energy of the display device is low. In recent years, with the rapid development of various display devices, more attention has been paid to how to improve the utilization rate of light energy, which is also a technical p...
