摘要： A scan driving circuit includes a shift register unit and a logic circuit unit. The start of a start pulse of an output signal STp+1 of a p+1'th shift register is situated between the start and end of a start pulse of the output signal STp of a p'th shift register, and one each of a first enable signal through a Q'th enable signal exist in sequence between the start of the start pulse of the output signal STp and the start of the start pulse of the output signal STp+1. The operations of a (p′, q)'th NAND circuit are restricted based on period identifying signals, such that the NAND circuit generates scanning signals based only on a portion of the output signal STp corresponding to the first start pulse, the signal obtained by inverting the output signal STp+1, and the q'th enable signal ENq.

摘要： A light emitting diode (LED) display includes a substrate, a pixel define layer, at least one first color micro LED, and at least one second color micro LED. The pixel define layer is disposed on the substrate and has a first opening and a second opening separated from each other. Contours of the first and second openings on a surface of the pixel define layer facing away from the substrate respectively define areas which are the same as each other. The first color micro LED is disposed in the first opening and has a first vertical projection projected on the substrate. The second color micro LED is disposed in the second opening and has a second vertical projection projected on the substrate. An area of the first vertical projection is different from an area of the second vertical projection.
