Embodiment 1

[0038] Please refer to Figures 1 to 10 , this embodiment provides a display panel, including a first substrate 1 and a second substrate 2 oppositely arranged, and a plurality of reflective structures 3 are arranged between the first substrate 1 and the second substrate 2; the second substrate 2 is used for The light emitted by the light source is transmitted; the reflective structure 3 is used for at least one total reflection of the received light transmitted by the second substrate 2 to form outgoing light; the first substrate 1 is used for transmitting the outgoing light.

[0039] It should be noted that the display panel of this embodiment is a display panel added with a color-changing material 7 .

[0040] Please refer to figure 1 ,From figure 1 It can be seen from the figure that the first substrate 1 and the second substrate 2 are arranged opposite to each other, and a color-changing material 7 and a plurality of reflective structures 3 are arranged between the first...

Embodiment 2

[0066] Please refer to Figure 11 and Figure 12 , this embodiment provides a display panel, including a first substrate 1 and a second substrate 2 oppositely arranged, and a plurality of reflective structures 3 are arranged between the first substrate 1 and the second substrate 2; the second substrate 2 is used for The light emitted by the light source is transmitted; the reflective structure 3 is used for at least one total reflection of the received light transmitted by the second substrate 2 to form outgoing light; the first substrate 1 is used for transmitting the outgoing light.

[0067] It should be noted that the display panel of this embodiment is a display panel added with a color-changing material 7 .

[0068] Please refer to Figure 11 ,From Figure 11 It can be seen from the figure that the first substrate 1 and the second substrate 2 are arranged opposite to each other, and a color-changing material 7 and a plurality of reflective structures 3 are arranged bet...

Embodiment 3

[0084] Please refer to Figure 13 , the present embodiment provides a display panel, which has a structure similar to that of the display panel in Embodiment 2. The difference between it and Embodiment 2 is that the display panel also includes a The reflective structure 3 corresponds to the support body 5 , the reflective structure 3 on the second substrate 2 is located on the support surface of the corresponding support body 5 , and there is a preset angle between the support surface and the second substrate 2 .

[0085] From Figure 13 It can be seen from the figure that a support body 5 is provided on the second substrate 2, the support body 5 has a support surface, and a reflective structure 3 is provided on the support surface, and there is a preset angle between the support surface and the second substrate 2, to tilt the support surface. Preferably, the reflective structure 3 on the support surface corresponds to the interval between two adjacent reflective structures ...

Abstract

The invention provides a display panel and a display device and belongs to the technical field of display. The problem of high transmittance but lower contrast ratio of the display device of the prior art can be solved. The display panel provided by the invention comprises a first base plate and a second base plate which are oppositely arranged; a plurality of reflecting structures are arranged between the first base plate and the second base plate; the second base plate is used for transmitting the light emitted from a light source; the reflecting structures are used for fully reflecting the received light transmitted by the second base plate for at least one time, so as to form the emitting light; the first base plate is used for transmitting the emitting light.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to a display panel and a display device. Background technique [0002] Currently, a display device generally includes a display panel and a polarizer positioned above the display panel. The polarizer can allow light vibrating in a specific direction to pass through, but at the same time results in a low transmittance of the display device. [0003] In order to improve the transmittance of the display device, a color-changing material can be added to the display panel, and the state of the color-changing material can be controlled by arranging electrodes in the display panel, thereby increasing the transmittance of the display device. For example, applying a voltage to the electrodes turns the color-changing material into a transparent state, allowing light to pass through; without applying a voltage to the electrodes, the color-changing material becomes opaque, preventi...
