Abstract

The present invention discloses a display panel and a display device. The display area of the display panel comprises a transmissive area and a reflective area; the transmissive area comprises color sub-pixels, and the reflective area comprises black and white sub-pixels; first common electrodes are arranged on a color filter substrate corresponding to both the transmissive area and the reflectivearea; a plurality of first pixel electrodes are arranged at the portion of an array substrate corresponding to the transmissive area, and the first pixel electrodes are corresponding to the color sub-pixels; a plurality of second pixel electrodes, a reflective layer and a plurality of first thin film transistors are arranged at the portion of the array substrate corresponding to the reflective area, and the second pixel electrodes are corresponding to the black and white sub-pixels; one first thin film transistor is correspondingly connected with one first pixel electrode; second common electrodes are arranged on the array substrate corresponding to both the transmissive area and the reflective area, and the second common electrode is arranged between the first thin film transistor and the first pixel electrode; and voltage signals applied to the second common electrode and the first common electrode are the same. According to the technical scheme of the present invention, the displayeffect of the black and white color switching display can be improved.

Description

technical field [0001] The present invention relates to the field of display technology, and more particularly, to a display panel and a display device. Background technique [0002] With the rapid development of electronic products towards lightness, thinness and miniaturization, more and more liquid crystal display modules are applied to electronic products, especially in camcorders, notebook computers, desktop computers, smart TVs, mobile terminals, Personal digital processors and other mobile terminals. [0003] Existing terminal electronic products have high requirements on power consumption. At present, a dual-screen design is proposed for low power consumption, that is, a black-and-white display and a color display to realize black-and-white and color switching display. For example, a color display with higher power consumption is used in a normal use state, and a black and white display with a lower power consumption is used in a standby state. However, due to the ...
