Display panel, display device and driving method of display panel

Abstract

The invention discloses a display panel, a display device and a driving method of the display panel. The display panel includes a first substrate and a second substrate which are arranged oppositelyrelative to a box, point light sources arranged in an array are arranged on the side, away from the second substrate, of the first substrate, optical coupling devices corresponding to the point light sources one to one are arranged on the side, close to the second substrate, of the first substrate, optical grating layers are arranged on the sides, away from the first substrate, of the optical coupling devices, and a liquid crystal layer is arranged between the first substrate and the second substrate; and the optical coupling devices are used for reflecting light rays which are emitted by the corresponding point light sources and penetrating through the first substrate to reach the optical coupling devices into the first substrate, and the light rays are completely reflected and propagated in the first substrate. According to the display panel, the display device and the driving method of the display panel, the problems that according to transparent liquid crystal display (LCD) panels inthe prior art, the display brightness is uneven and energy is low in the whole LCD panels due to use of side-entry backlight modules are solved.

Description

technical field [0001] The present application relates to but not limited to the field of optoelectronic technology, especially a display panel, a display device, and a driving method of the display panel. Background technique [0002] With the development of display technology and the wide application of display devices, transparent display devices have become a mainstream product type in display products due to their wide application scenarios. Existing common liquid crystal display (Liquid Crystal Display, referred to as: LCD) devices, in order to achieve a transparent display effect, usually use a side-type backlight module, that is, the light source enters from the side of the lower substrate, and the display is realized through the backlight module. Effect. [0003] The existing LCD panel realizes the transparent display effect through the side-type backlight. Due to the influence of the light output mode of the side-type backlight, there are problems of uneven displa...
