Embodiment Construction

[0027] The specific implementation manner of the present invention will be further described below in conjunction with the drawings and embodiments. The following examples are only used to illustrate the present invention, but not to limit the scope of the present invention.

[0028] In this embodiment, a display panel is firstly provided. The display panel mainly includes an array substrate and a color filter substrate arranged opposite to each other. A liquid crystal layer is arranged between the array substrate and the color filter substrate. The liquid crystal layer equivalently forms a quarter A liquid crystal wave plate. Since the display panel provided in this embodiment can be equivalent to a quarter liquid crystal wave plate, it can cooperate with a polarized light source and a polarizer to form a transparent display device, and use a quarter liquid crystal wave plate to adjust the phase of polarized light. Change, thereby improving the transparent display effect of ...

Abstract

The invention relates to the display technical field, in particular to a display panel and a transparent display device. According to the transparent display device, a polarization light source supplies elliptically polarized light or circularly polarized light to the display panel, a liquid crystal layer equivalently forms a quarter of a liquid crystal wave plate, then after passing through the quarter of the liquid crystal wave plate equivalently formed by the liquid crystal layer, the elliptically polarized light or the circularly polarized light can form linearly polarized light, therefore, an upper polarizer on a color film substrate can not be transmitted, when the liquid crystal layer is powered up, the elliptically polarized light or the circularly polarized light can partially transmit the upper polarizer on the color film substrate, and then the image display effect is achieved; natural light can transmit the upper polarizer on the color film substrate and then transmit the display panel, and then the transparent effect is achieved; according to the transparent display device, due to the fact that the polarizer does not need to be arranged on an array substrate, the transmittance of the display panel is improved, the transparent effect of the transparent display device is greatly improved, and therefore the effect for improving user experience is improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display panel and a transparent display device using the display panel. Background technique [0002] Thin Film Transistor-Liquid Crystal Display (TFT-LCD) is widely used in televisions, mobile phones, monitors and other electronic products due to its advantages of stable picture, vivid image, radiation elimination, space saving and energy saving. , has occupied a dominant position in the flat panel display field. [0003] However, with the development of information technology, the transparent display technology that allows viewing of objects on the back and can realize screen display has attracted more and more attention. The transparent display device has a certain degree of penetration. When a voltage is applied, information can be displayed on the display panel. When no voltage is applied, the background behind the transparent display device can be seen through the displ...
