Embodiment Construction

[0052] In order to make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be described clearly and completely in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art fall within the protection scope of the present invention.

[0053] Such as figure 1 As shown, the current display device modulates the Lambertian light emitted by the LED light source 1 through a free-form surface mirror 2 and couples it into the light guide plate 3 at a certain central angle, and transmits it in the light guide plate 3 in a way of total reflection. The light-emitting surface or the b...

Abstract

The invention relates to a display panel, which comprises a light guide plate, a plurality of light extraction units, and a gray scale control unit. The light guide plate is configured to transmit thelight injected into the light guide plate in total reflection form in the light guide plate; the plurality of light extraction units in one-to-one correspondence with the sub-pixel units are configured to take out the light rays transmitted by total reflection in the light guide plate in the form of monochromatic light corresponding to the color of the sub-pixel units; the gray scale control unitis used for adjusting the transmittance state of the monochromatic light. The invention further relates to a display device and a driving method. The beneficial effects of the present invention are that: realizing the color backlight effect, no need to arrange a POL (polaroid) and a color film structure so that realizing the color display, and improving the light utilization rate.

Description

Technical field [0001] The invention relates to the technical field of liquid crystal product manufacturing, in particular to a display panel, a display device and a driving method. Background technique [0002] At present, the light extraction grating of the backlight part can only collimate light of a single color, and the light source can only be monochromatic light, so it is essentially a monochromatic display solution. Summary of the invention [0003] In order to solve the above technical problems, the present invention provides a display panel, a display device and a driving method to solve the problem that the backlight part of the display device can only achieve monochrome display. [0004] In order to achieve the above objective, the technical solution adopted by the present invention is: a display panel including: [0005] The light guide plate is configured to transmit the light entering the light guide plate in the light guide plate in the form of total reflection; [000...
