A brightness control method of a spliced display device is provided. The spliced display device includes display units, and each display unit includes a LED display area and an LCD area. The brightness control method includes obtaining a current grayscale value of a current frame and a target grayscale value of a target frame in the LCD area, wherein the target frame is the frame next to the current frame; obtaining a response time required to convert the current grayscale value into the target grayscale value of the LCD area; and adjusting a target grayscale value of the LED area to an actual grayscale value during the target frame according to the response time. During the target frame, the brightness emitted by the LED display area based on the actual grayscale value is the same as the brightness emitted by the LCD area based on the target grayscale value.

Spliced display device and brightness control method thereof

A display panel includes a first substrate, a second substrate, light-emitting elements, a gate driving structure and light-shielding traces. The second substrate is disposed opposite to the first substrate. An active area, a first peripheral area and a second peripheral area of the first substrate overlap an active area, a first peripheral area and a second peripheral area of the second substrate respectively. The light-emitting elements are disposed on the first peripheral area and the second peripheral area of the first substrate, or the light-emitting elements are disposed on the first peripheral area and the second peripheral area of the second substrate. The gate driving structure is disposed on the first peripheral area of the second substrate. The gate driving structure includes a device layer and a light-shielding pattern overlapped with the device layer. The light-shielding traces are disposed on the second peripheral area of the second substrate.

Pixel structure

A display panel includes a substrate, a first circuit routing area, a second circuit routing area, a plurality of first gate lines, a plurality of second gate lines, a plurality of first drive lines and a plurality of second drive lines. Each of the first gate lines and one of the second gate lines intersect at a first intersect point. Each of the first drive lines and one of the second drive lines electrically connect at a second intersect point. The distance on the first direction between one of the first intersect points and one of the second intersect points on the second direction is smaller than the width of a liquid crystal subpixel on the first direction.
