Abstract: The present invention provides a display panel and a display device. Within a bezel region, the display panel includes a first substrate and a second substrate arranged corresponding to each other. A protrusion is placed on a first surface of the first substrate, which faces the second substrate. The display panel also includes a sealing adhesive filled in a gap between the first substrate and the second substrate. Because of the protrusion, a contact area between the first substrate and the sealing adhesive is increased, a longer path for entry of moisture is created, and the display panel, such as a liquid crystal display, has a better waterproofing.

Abstract: An array substrate comprises a display region provided with a thin film transistor circuit; a non-display provided with a drive circuit, at least one anti-static circuit and a dummy thin film transistor circuit. By disposing the dummy thin film transistor circuit and at least one of the anti-static circuits between the thin film transistor circuit and the drive circuit, the static electricity will not be released into an overlap region of a gate line and a polysilicon line, thereby solving technical problem that short circuit occurs between a gate layer and a polysilicon active layer.

Abstract: A color filter substrate and a liquid crystal display panel are provided. The color filter substrate includes photoresist blocks spaced apart, a black matrix disposed between adjacent photoresist blocks, an optically thinner medium film disposed on the photoresist blocks and the black matrix, and an overcoat layer covering the photoresist blocks, the black matrix, and the optically thinner medium film. The optically thinner medium film covers a boundary between the photoresist blocks and the black matrix. A refractive index of the optically thinner medium film is less than that of the overcoat layer. The color filter substrate and a TFT array substrate are formed into the liquid crystal display panel. Light is totally reflected at an interface between the overcoat layer and the optically thinner medium film, thereby solving issues of color shifts at large viewing angles without affecting transmittance of the liquid crystal display panel.

Abstract: The OLED tiled display includes front and back lighting display units that emitting lights toward each other. The front lighting display unit includes a first substrate and a first organic light emitting device. The back lighting display unit includes a second substrate and a second organic light emitting device. The first and second light emitting devices neighbor laterally on each other, but are vertically aligned to a second extended section of the second substrate and a first extended section of the first substrate, respectively. The present invention achieves small gaps and resolves the problem of obvious gaps in an OLED tiled display by piecing together the front and back lighting display units, where the substrate of the front lighting display unit functions as encapsulation layer to the back lighting display unit, and the substrate of the back lighting display unit functions as encapsulation layer to the front lighting display unit.
