Abstract

The invention discloses a reflective type display panel and a driving method thereof and a control method of a pixel unit thereof. The reflective type display panel comprises a substrate, a reflective layer, a pixel defining layer, a first electrode layer and a second electrode layer, wherein a plurality of pixel units are defined by the pixel defining layer; the first electrode layer is located at one side, facing backward to the substrate, of the pixel defining layer, the second electrode layer is located at one side, facing backward to the substrate, of the first electrode layer and is insulated from the first electrode layer, the materials of the first electrode layer and the second electrode layer are both electrooptical materials, the forward projection of the second electrode layer on the substrate and the forward projection of the first electrode layer on the substrate constitute an overlapped area, and the overlapped area and the pixel unit are correspondingly arranged. According to the reflective type display and the driving method thereof and the control method of the pixel unit thereof, under the condition of no need to arrange a switch transistor, the first electrode layer and the second electrode layer in a corresponding area in the pixel unit are utilized to control a phase of reflective light reflected from the surface of the second electrode layer so as to control opening and closing of the corresponding pixel unit.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a reflective display panel, a driving method thereof, a control method of a pixel unit, and a reflective display device. Background technique [0002] In the field of display technology, according to different types of light sources used, displays can be roughly divided into three types: transmissive displays, reflective displays, and transflective displays. Among them, the reflective display has the characteristic of super power saving because it does not need to be provided with a backlight module to provide a light source. [0003] The reflective display in the prior art is generally based on a liquid crystal cell. The liquid crystal cell includes: a first substrate and a second substrate oppositely arranged, and a control electrode for controlling the deflection of the liquid crystal molecules is arranged on the first substrate and the second substrate. The liquid crystal ce...
