Embodiment Construction

[0038]In order to make the objects, technical solutions, and advantages of the present invention, embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that the features in the embodiments and embodiments in the present application may be any combination with each other in the case of an unable conflict.

[0039]In the above background, it has been explained that existing ordinary LCD display panels, in order to achieve transparent display, it is often necessary to use the edge into the light, that is, the side-type backlight module, which causes the light intensity as lighting The increase in the number of times is weakened. In order to solve the problem of the above-mentioned light intensity, it is necessary to design different light ports in different lighting positions, which adds a certain amount of cost for processing. Such asfigure 1 As shown, a schematic diagram of a light source structure in an ex...

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 arranged in a box, the side of the first substrate away from the second substrate is provided with point light sources arranged in an array, and the side of the first substrate close to the second substrate is provided with a The optical coupling device corresponding to the light source one by one, the optical coupling device is provided with a grating layer on the side away from the first substrate, and a liquid crystal layer is provided between the first substrate and the second substrate; the optical coupling device is used to emit the corresponding point light source The light passing through the first substrate and reaching the optical coupling device is reflected into the first substrate, so that the light propagates through total reflection in the first substrate. The invention solves the problems of non-uniform display brightness and low energy in the entire LCD panel due to the use of a side-entry backlight module in the transparent LCD panel in the prior art.

Description

Technical field[0001]The present application relates not limited to, in the field of optoelectronic technology, particularly, a display panel, a display device, and a driving method of the display panel.Background technique[0002]With the development of display technology, the extensive application of display devices, transparent display devices become a mainstream product type in its extensive application scenario. The existing common liquid crystal display (LQID CRYSTAL DISPLAY) device, in order to achieve a transparent display effect, a side-type backlight module, that is, the light source is entered from the side surface of the lower substrate, and displayed by a backlight module effect.[0003]The existing LCD panel implements the transparent display effect by side-type backlight, and is affected by the lateral backlight source, there is a problem that the brightness is uneven, and the low energy is low in the entire LCD panel, especially for large-size LCD panels. Under the appli...
