Abstract: A display panel, including an active area and a peripheral area, which is located outside of the active area, wherein the active area comprises a base substrate, and a display structure layer and a touch structure layer sequentially arranged on the base substrate; the peripheral area includes an isolation dam, a first ground trace and a second ground trace arranged on the base substrate; and the first ground trace is located at a side of the isolation dam close to the active area, and the second ground trace is located at a side of the isolation dam away from the active area.

Abstract: An angle fixing fixture relates to the field of tooling fixtures and includes: a right-angled triangle shaped positioning block and clamping claws. Each the clamping claw is provided with a clamper, and a position of the clamper on the clamping claw is adjustable. Each the clamping claw is detachably connected to the positioning block. The clamper is located outside the positioning block, and a certain distance is left between the clamper and the positioning block. An end surface of an end of the clamper close to the positioning block is parallel to one of outer side surfaces of the positioning block. The number of the clamping claws is at least two. The angle fixing fixture can meet the need of 90 degrees connection of two plates as well as the needs of other angle connections, and has a simple structure and is easy to use.
