Abstract: A display panel and a display device are disclosed. The display panel includes a first substrate, a second substrate, and a liquid crystal layer disposed therebetween. The first substrate includes a first base and a planarization layer disposed on a side of the first substrate adjacent to the liquid crystal layer. A side of the planarization layer adjacent to the liquid crystal layer includes a textured structure, which includes at least one groove path. The first substrate further includes a bottom edge. An extending direction of the at least one groove path forms an included angle with the bottom edge, the included angle being greater than or equal to 45 degrees and less than or equal to 135 degrees. A liquid crystal material in the liquid crystal layer diffuses along the extending direction of the groove path through the groove path based on capillary phenomenon.

Abstract: Disclosed are a thin film transistor structure, a display panel and a display device. The thin film transistor structure includes a base, a source electrode, a drain electrode configured to connect to a pixel electrode and a grid electrode. The source electrode, the drain electrode and the grid electrode are provided on the base. and a channel is formed between the source electrode and the drain electrode. The thin film transistor structure further includes an insulating layer and a slow-release electrode. The insulating layer is provided on a side of the source electrode and the drain electrode, and filled in the channel. The slow-release electrode is provided in the insulating layer. At least a part of the slow-release electrode is provided inside the channel.

Abstract: The invention discloses an ultrasonic fat reduction and body shaping machine that includes a treatment head, a wave source carrying apparatus, a mechanical arm, a treatment bed, a lift cylinder body, a touch screen and control circuits. A menu for user selection operation is provided on the touch screen. The treatment head is clamped in the wave source carrying apparatus so as to be fixedly connected to the mechanical arm as a whole. The mechanical arm is fixedly connected to the lift cylinder body that is fastened on the treatment bed-base. The invention is to provide an ultrasonic fat reduction and body shaping machine that facilitates assembling and disassembling of a treatment head, elevates and descends a mechanical arm freely. The ultrasonic fat reduction and body shaping machine has an ultrasonic frequency of 1 MHz to 3 MHz using an ultrasonic emission mode with high intensity, narrow pulse width and low duty cycle.
