Problems solved by technology

When viewed from the array substrate side, due to the reflection of the gate metal and the source-drain metal layer, it will cause viewing from the array substrate side, the contrast is lower than that of the color filter substrate side, and the glare is serious.

Abstract

The invention discloses a two-sided transparent display device. The two-sided transparent display device comprises an array substrate, an opposite type substrate and a display dielectric layer. The array substrate is sequentially provided with a first black matrix pattern, a first metal layer pattern, a first metal insulation layer, a semiconductor layer, a second metal layer pattern, a protective insulation layer, a transparent organic insulation film and a pixel electrode in a matched mode, wherein the first black matrix pattern covers the first metal layer pattern and the second metal layer pattern. One side, facing the array substrate, of the opposite type substrate is provided with a second black matrix pattern in a matched mode. The second black matrix pattern covers the first metal layer pattern and the second metal layer pattern. The display dielectric layer is clamped between the array substrate and the opposite type substrate. The two-sided transparent display device can be watched from the obverse side and the reverse side, and the two sides are coincident in contrast ratio and are the same in display effect.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a double-sided transparent display device. Background technique [0002] A thin film transistor liquid crystal display (TFT-LCD) is jointly formed by an array substrate, a color filter substrate and a liquid crystal sandwiched between the two substrates. A TFT-LCD without a backlight is equivalent to a liquid crystal light valve plate. Under bright ambient light, the liquid crystal light valve plate is driven by a driving circuit so that the viewer can see the scene behind the TFT-LCD. [0003] A device that allows the viewer to see the scene behind the display screen through the display screen is called a transparent display, and it is more common and can be applied to display screens before displaying physical objects, such as shop windows. There are many kinds of display technologies that can be used in the display panel matched with the transparent display, so they are wide...
