Embodiment Construction

[0031] Aiming at the problem of low utilization rate of ambient light in reflective displays in the prior art, embodiments of the present invention provide a display panel and a display device.

[0032] The specific implementation manners of the display panel and the display device provided by the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The thickness and shape of each film layer in the drawings do not reflect the real scale, and the purpose is only to illustrate the content of the present invention.

[0033] In a first aspect, an embodiment of the present invention provides a display panel, such as figure 1 As shown, it includes: a base substrate 10, a reflective layer 11 located on the base substrate 10, a dielectric grating layer 12 located on the side of the reflective layer 11 away from the base substrate 10, and a dielectric grating layer 12 located on the side away from the base substrate 10. Th...

Abstract

The invention discloses a display panel and a display device. The display panel comprises a substrate, a reflecting layer located on the substrate, a dielectric grating layer, a filter layer and a color film layer; the color film layer comprises a first color film unit used for penetrating through light of a first color, a second color film unit used for penetrating through light of a second color, and a third color film unit used for penetrating through white light; the filter layer is used for transmitting the light of the first color and the second color, and reflecting the light of the third color; the dielectric grating layer comprises a grating unit corresponding to the position of the third color film unit; and the grating unit is used for reflecting the light of the first color transmitted by the filter layer to the first color film unit, and reflecting light of the second color transmitted by the filter layer to the second color film unit. The display panel provided by the embodiment of the invention improves the light utilization efficiency.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] The human eye can recognize all kinds of objects and colors in nature, all of which use the reflection of ambient light on the surface of the object. Therefore, it is feasible and has great application prospects to make full use of the reflection of ambient light to realize display. However, since the luminous angle of ambient light is divergent and its intensity is weak throughout the space, fully improving the utilization of ambient light is the direction of efforts for reflective display. [0003] Since the reflective display uses ambient light, does not require a backlight source, and has the characteristics of eye protection and low power consumption, the currently used reflective display filters the ambient light through a color film to form the three primary colors required for display, and then reflects ...
