Abstract: The present disclosure provides a light-emitting pixel layout structure, a display panel and an electronic device, relating to the technical field of display technology, which solves the problem of display image deformation caused by layout of existing light-emitting diode (LED) pixels. Light-emitting pixels include primary color pixels 101, primary color pixels 102 and primary color pixels 103, the layout structure includes homogeneous primary color rows arranged in an interlaced manner and heterogeneous primary color rows formed by alternate layout of the other two primary color pixels. The present disclosure is applicable to any existing display structure that uses a plurality of point or block light sources as light-emitting pixels. The present disclosure can improve the clarity of a display screen, avoid display deformation, avoid color lines at edges after cutting, obtain a high pixel resolution, and improve the degree of fusion of image edges.

Abstract: A display driver circuitry with permutation and superposition gray-level control comprises a gray-level controller. The controller may comprise a permutation and superposition adder configured to divide N-bit gray-level data G into M most significant bits, serving as a superposition reference GH, and (N?M) least significant bits, serving as a superposition increment GL, and to superpose superposition values Xi onto GH to derive pieces of scan data Gi for S scan operations; an overflow bit setting unit configured to set an overflow bit F; and an output unit configured to output the scan data Gi. A display driven this way has an improved refreshing frequency with the same gray-level reproduction ability as PWM-based schemes. Further, the duration of each scan operation, or scan period, is constant, resulting in convenience in software implementations. Furthermore, the pulse width representative of the gray-level value is determined by superposition of the scan operations.
