Problems solved by technology

The current transparent display panel includes a pixel display area for displaying pictures and a light transmission area between the pixel display areas. With the improvement of resolution, the size of the light transmission area becomes smaller and smaller. However, when the size of the light transmission area If the size is too small, due to the arrangement of the pixel display area and the periodic rows of the light-transmitting area, the ambient light on the back of the display panel will be diffracted when it passes through the light-transmitting area during the transparent display process, resulting in ghosting

Abstract

The embodiment of the invention provides a transparent display panel, a control method thereof and a display device, and relates to the technical field of display. The diffraction probability in the transparent display process can be reduced on the premise of ensuring the resolution ratio, and therefore the double image phenomenon is eliminated. The transparent display panel comprises a pixel display area, a light-permeable area, a display film layer, a polaroid, a light valve film layer and a first dual-refraction film layer, wherein a light-emitting device is arranged at the position, corresponding to the pixel display area, of the display film layer, the light-permeable area is of a light-permeable structure, the polaroid is located on the light outlet side of the display film layer andused for converting the emergent light of the light-emitting device into polarized light, the light valve film layer is located on the side, away from the display film layer, of the polaroid and usedfor converting the polarized light between the polarized light in the first direction and the polarized light in the second direction, and the first dual-refraction film layer is located on the side,away from the polaroid, of the light valve film layer and used for making the polarized light in the first direction emitted out of the pixel display area and the polarized light in the second direction emitted out of the light-permeable area.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a transparent display panel, a control method thereof, and a display device. Background technique [0002] The transparent display panel can allow the user to see the scene behind it through the display panel while displaying the picture. The current transparent display panel includes a pixel display area for displaying pictures and a light transmission area between the pixel display areas. With the improvement of resolution, the size of the light transmission area becomes smaller and smaller. However, when the size of the light transmission area If the size is too small, due to the arrangement of the pixel display area and the periodic rows of the light-transmitting area, the ambient light on the back of the display panel will be diffracted when passing through the light-transmitting area during the transparent display process, resulting in ghosting.
