Embodiment 1

[0033] refer to figure 2 , showing a schematic structural diagram of a display panel according to an embodiment of the present invention, image 3 A schematic structural diagram of another display panel according to an embodiment of the present invention is shown.

[0034] An embodiment of the present invention provides a display panel, including: a liquid crystal layer 21, a polarizer 22 disposed on the light-emitting side of the liquid crystal layer 21, and a quarter wave plate 23 sequentially disposed on the side of the liquid crystal layer 21 away from the polarizer 22 , transflective layer 24 and electrochromic layer 25; Wherein, the included angle of the optical axis of quarter-wave plate 23 and the transmission axis of polarizer 22 is 45 °, and the slow axis of liquid crystal layer 21 and polarized light The included angle of the transmission axis of the sheet 22 is 45°.

[0035] Wherein, the transflective layer 24 is a CLC (Cholesteric Liquid Crystal, cholesteric li...

Embodiment 2

[0067] refer to Figure 9 , shows a schematic structural diagram of a display device according to an embodiment of the present invention.

[0068] An embodiment of the present invention provides a display device, which includes a backlight 31 and the above-mentioned display panel. The backlight 31 is disposed on the side opposite to the light-emitting side of the display panel.

[0069] Specifically, when the quarter-wave plate 23, the transflective layer 24, and the electrochromic layer 25 are arranged on the side of the array substrate 26 close to the liquid crystal layer 21, the backlight 31 is arranged on the array substrate 26 away from the electrochromic layer. One side of the layer 25; when the quarter wave plate 23, the transflective layer 24 and the electrochromic layer 25 are arranged on the side of the array substrate 26 away from the liquid crystal layer 21, the backlight 31 is arranged on the electrochromic layer 25 away from the side of the transflective layer 2...

Abstract

The invention provides a display panel, a display device and a driving method thereof and relates to the field of display technologies. According to the method, a polarizer is arranged at the light-out side of a liquid crystal layer, a quarter-wave plate, a semi-transmissive semi-reflective layer and an electrochromic layer are arranged at the side, away from the polarizer, of the liquid crystal layer, the included angle between the optical axis of the quarter-wave plate and the transmission axis of the polarizer is 45 degrees, and the included angle between the slow axis of the liquid crystallayer and the transmission axis of the polarizer is 45 degrees. Through mutual cooperation of the polarizer, the liquid crystal layer, the quarter-wave plate, the semi-transmissive semi-reflective layer and the electrochromic layer, display is performed depending on a reflection mode of the display panel in a bright environment, and display is performed depending on a transmittance mode of the display panel in a dark environment; and in the bright environment and the dark environment, all regions of each pixel in the display panel work normally, therefore, the transmittance and reflectivity of the display panel are improved, and the display effect is improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel, a display device and a driving method thereof. Background technique [0002] The transmissive display panel usually needs a backlight to realize the display, which has a good display effect indoors, but the contrast will decrease due to the reflection of the outdoor ambient light, while the reflective display panel uses the ambient light to realize the display, but due to the indoor environment It is difficult to provide the required light when the light is dark, and the transflective display panel can rely on its transmissive mode to display in a dark ambient light, and rely on its reflective mode to display in a bright environment. It is suitable for environments with various light intensities, so it is widely used in vehicle displays, mobile phones, digital cameras and other products. [0003] However, the current transflective display panel divides ...
