Abstract: An array substrate includes an opening area and a non-opening area, and further includes a first substrate, a gate insulating layer, a first interlayer insulating layer, and a second interlayer insulating layer. The gate insulating layer is disposed on the first substrate and located in the opening area and the non-opening area. The first interlayer insulating layer is disposed on a side of the gate insulating layer away from the first substrate and located in the non-opening area. The second interlayer insulating layer is disposed on a side of the first interlayer insulating layer away from the first substrate and located in the opening area and the non-opening area. A projection of the first interlayer insulating layer on the first substrate is tangent to or separated from a projection of the opening area on the first substrate. A display panel includes the array substrate.

Abstract: The present application provides a display panel and an electronic device. The electronic device includes a display panel. The display panel includes a backlight module. The backlight module includes a frame, an optical film group, and a fixing block. Movements of the optical film group can be limited in a thickness direction of the display panel by pressing the fixing block on the optical film group. Therefore, optical films can be fixed, so problems of abnormal noise, displacement, and scratches of the optical films in the display panel adopting a direct-lit mini light-emitting diode (LED) light source are prevented.

Abstract: A liquid crystal display panel and a vehicle-mounted liquid crystal display device are provided. In the liquid crystal display panel, in an array substrate and/or a color filter substrate, a number of reflective interfaces in a functional area is greater than a number of reflective interfaces in a display area. Under the condition that an infrared optical transmittance is not affected, a reflectivity of light in the functional area is improved compared to the display area. This reduces or even eliminates a brightness difference between the functional area and the display area when a display is completely black.

Abstract: A thin-film transistor (TFT) having a vertical structure and an electronic device are provided. The TFT having the vertical structure includes an insulating substrate and an active layer disposed on the insulating substrate. The active layer includes a first conductive part, an active section, and a second conductive part which are stacked. An orthographic projection of the first conductive part on the insulating substrate partly overlaps an orthographic projection of the second conductive part on the insulating substrate. Therefore, contamination ions may be prevented from entering the active section from the insulating substrate during manufacturing processes of the TFT. Thus, reliability of performance of the TFT may be improved.
