Abstract: The present application provides a display panel. Blocks of the display panel have the characteristic of random arrangement, which can eliminate a ghosting problem caused by periodic arrangement, and the randomness is subjected to some limitations and restrictions, thereby avoiding the wiring difficulty in the related art in which blocks are arranged completely randomly.

Abstract: Disclosed are a spatial light modulator and a display device, where 2*2 adjacent pixel electrodes are a pixel group, through-holes corresponding to the respective pixel electrodes are located proximate to the center of the pixel group, and a photo spacer is located at the center of the pixel group, so that the photo spacer can overlap with the through-holes, or the photo spacer can be arranged in close proximity to the through-holes. If the photo spacer overlaps with the through-holes, then a black matrix layer covering the photo spacer, and a black matrix layer covering the surrounding of the photo spacer may cover at least a part of the through-holes; and if the photo spacer is arranged in close proximity to the through-holes, then the black matrix layer covering the surrounding of the photo spacer may cover at least a part of the through-holes.

Abstract: A 3D display screen and a 3D display device are provided. The 3D display screen comprises a pixel array comprising m laterally displaced groups. The laterally displaced group includes n rows of sub-pixel units, the sub-pixel units in a same sub-pixel unit row are arranged in a first lateral direction, m is a positive integer larger than or equal to 1, and n is a positive integer larger than or equal to 2. The sub-pixel unit includes a plurality of light-shielding stripes, and two adjacent light-shielding stripes have a gap of P in the first lateral direction. Along the first lateral direction, the nth sub-pixel unit row has a lateral displacement of P with respect to the 1st sub-pixel unit row, the ith sub-pixel unit row has a lateral displacement of P/n with respect to the (i-1)th sub-pixel unit row, where i is a positive integer and 1

Abstract: A method of electrically testing an in-cell touch screen is disclosed. The in-cell touch screen includes a display electrode, a driving line, and a detecting line. The detecting line intersects the driving line. The method includes floating the display electrode and performing at least one of: A) applying a first predetermined voltage to one column of adjacent columns of the driving line or one row of adjacent rows of the driving line, and grounding the other column of the adjacent columns or the other row of the adjacent rows, and B) applying a second predetermined voltage to one column of adjacent columns of the detecting line or one row of adjacent rows of the detecting line, and grounding the other column of the adjacent columns or the other row of the adjacent rows. The method also includes determining whether the driving line or the detecting line is shorted or opened.
