Disclosed in the present application is a demultiplexer and a driving method thereof, and a display panel having the demultiplexer. Each output channel is respectively connected to (K−1) data lines through (K−1) switching transistors and directly connected to another data line; each metal electrode plate is disposed nearby to the another data line respectively, so that a feedthrough effect on the another data line is close to that on other (K−1) data lines, thereby achieving better display uniformity on the display panel.

Demultiplexer and driving method thereof, and display panel having demultiplexer

The present application discloses a display panel and a display device. A first metal layer includes at least one first signal transmitting portion. An insulating layer includes a protrusion portion covering the first signal transmitting portion. A second metal layer includes at least one second signal transmitting portion. The second signal transmitting portion includes a first sub-portion, a second sub-portion, and a third sub-portion. The second sub-portion and the third sub-portion are respectively connected to two ends of the first sub-portion. A conductive layer includes a bridging portion. An orthographic projection of the second sub-portion on a substrate and an orthographic projection of the third sub-portion on the substrate both fall outside a coverage of an orthographic projection of the protrusion portion on the substrate. Two ends of the bridging portion are electrically connected to the second sub-portion and the third sub-portion respectively.

Display panel and display device

A display panel and a display device are provided, wherein an insulating layer covers a substrate and a first metal layer, and wherein the insulating layer includes a protruding portion covering a first signal transmission portion. A second metal layer is disposed on a side of the insulating layer away from the first metal layer and includes a second signal transmission portion, wherein the second signal transmission portion covers at least part of a sidewall of the protruding portion. The protruding portion includes a first sub-layer, a second sub-layer, and a first hole arranged at a sidewall of the protruding portion, wherein the first sub-layer is positioned on a side of the second sub-layer away from the first signal transmission portion, and wherein the second signal transmission portion extends into the first hole and contacts the second sub-layer.

The disclosure discloses a manufacturing method of a liquid crystal display grating. The method includes preparing a substrate, depositing a transparent film layer on the substrate, patterning the transparent film layer for producing a plurality of containing grooves, depositing a liquid crystal alignment film in the containing grooves, injecting liquid crystal molecules in the containing grooves, aligning and packaging the liquid crystal molecules. The disclosure can achieve 3D display by the method above.

Display device, liquid crystal display grating and manufacturing method

The present disclosure provides a stage-number reduced gate driver on array (GOA) circuit and a display device. The circuit includes one or more stages of GOA sub-circuits. Each stage of GOA sub-circuits includes a gate signal input end, an original output end, one or more sub-output ends, and one or more branching devices respectively corresponding to the one or more sub-output ends. The gate signal input end and the original output end are respectively connected to a branching node. One end of the one or more branching devices is respectively connected to the branching node. Another end of the one or more branching devices is connected to the corresponding one or more sub-output ends. The present disclosure can solve the problem of excessive length of the GOA circuit in high-resolution model which is not conducive to a narrow bezel design.
