Problems solved by technology

Some reflective LCD display panels are equipped with a reflective layer on the side of the array substrate, and use the reflective layer to reflect the natural light incident from the outside to achieve display. However, when the ambient light becomes weak, it cannot display normally.

Embodiment Construction

[0045] Those skilled in the art should understand that the technical solutions of the embodiments of the present disclosure can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the embodiments of the present disclosure, and should be covered by the claims of the present disclosure.

[0046]Compared with transmissive LCD technology, reflective LCD technology not only has the advantage of low power consumption, but also takes into account the advantages of high PPI, because transmissive LCD technology needs to take into account the area occupied by the thin film transistor on the array substrate and the color film. The black matrix design on the substrate is designed to prevent cross-color and light leakage between adjacent sub-pixels, so the PPI improvement of the transmissive LCD is limited. However, the reflective display is not limited by this. The reflective display can hide all the thin film transistors under the...

Abstract

The embodiment of the invention provides a display panel, which relates to but is not limited to the technical field of display, and comprises a first substrate, a second substrate and a third substrate which are stacked in sequence, and a liquid crystal layer arranged between the first substrate and the second substrate, wherein the first substrate comprises a driving circuit layer arranged on the first substrate and a plurality of pixel electrodes arranged on the side, away from the first substrate, of the driving circuit layer; the third substrate comprises a plurality of light sources arranged on one side, facing the second substrate, of the third substrate, a flat layer covering the plurality of light sources, and a light conversion layer arranged on one side, deviating from the third substrate, of the flat layer; and the light conversion layer comprises a plurality of sub-conversion layers, the sub-conversion layers are arranged in the mode that light emitted by the light source enters the pixel electrodes, is reflected by the pixel electrodes and then irradiates the sub-conversion layers, and the sub-conversion layers are irradiated by the reflected light of the pixel electrodes to emit light of a set color. According to the display panel, normal display of the display panel at different viewing angles can be realized.

Description

technical field [0001] Embodiments of the present disclosure relate to but are not limited to the field of display technologies, and specifically relate to a display panel and a display device. Background technique [0002] With the continuous development of display technology, human beings are constantly improving in pursuit of display quality, such as high color gamut, high pixel density (PPI), low power consumption, etc. Reflective display technology initially received extensive attention and research due to its low power consumption. According to the display principle, reflective display technology can be divided into electronic paper technology and reflective liquid crystal display (LCD) technology. Compared with electronic paper technology, reflective LCD technology has It has the advantages of fast response speed and color display. Some reflective LCD display panels are provided with a reflective layer on one side of the array substrate, and the reflective layer is u...
