Abstract: A projection apparatus including: a light source component; a light polarization component for converting light from the light source component into first polarized light in a first polarization direction; a display panel on a side, away from the light source component, of the light polarization component for adjusting the polarization direction of the first polarized light to emit second polarized light in a polarization direction between the first polarization direction and a second polarization direction, the first polarization direction is perpendicular to the second polarization direction; a light reflective component on a side, away from the light polarization component, of the display panel for reflecting one of the polarized light in the first polarization direction and the polarized light in the second polarization direction; a projection lens, a light incident surface of which faces the light reflective component so as to receive light reflected by the light reflective component.

Abstract: An array substrate and a display panel are provided. The array substrate includes a display region and a first peripheral region surrounding the display region, the array substrate includes: a base substrate; gate lines, located on the base substrate and extending along a first direction; data lines, located on the base substrate and extending along a second direction, the second direction and the first direction cross each other; pixel electrodes, arranged in an array along the first direction and the second direction respectively; heating line groups, at least partially arranged in the display region, each of the heating line groups includes a plurality of first heating lines, and the first heating lines in each of the heating line groups are connected with each other through connection lines at two ends of the each of the heating line groups, respectively.

Abstract: An electronic device, including a touch screen. The touch screen includes a special-shaped touch region, and the special-shaped touch region includes multiple touch electrodes. The multiple touch electrodes include multiple first touch electrodes located in a non-edge region of the special-shaped touch region and multiple second touch electrodes located at an edge region of the special-shaped touch region; first edges of the multiple second touch electrodes coincide with the edge of the special-shaped touch region; the area ratios of the second touch electrodes to the first touch electrodes range from 0.9 to 1.1.
