Light-emitting panels, display devices, and methods for controlling light-emitting panels

Abstract

The invention refers to a light-emitting plate, a display device, and a method for controlling the light-emitting plate. A light-emitting plate includes at least one light-emitting control block {CU(x, y)}. The light-emitting control block (CU(x, y)) consists of light-emitting elements arranged in M ​​rows and N columns and grouped into a quantity of (PxQ) sub-blocks, where M is an integer equal to or greater than 1, N is an integer equal to or greater than 1, p is an integer equal to or greater than 1, and Q is an integer equal to or greater than 1; p groups of the first voltage signal lines (GPhl* Gph(p), .... GphP); and Q groups of the second voltage signal lines (Gnvl, .... Gnv(q)....... GNvQ). The quantity of (P*Q) sub-blocks is arranged in p rows and Q columns. The corresponding sub-block in row p and column q comprises K columns of light-emitting elements, where K is an integer equal to or greater than l. The display device consists of a light-emitting substrate and a reflective display panel*, where the light-emitting substrate is located on the display side of the reflective display panel.
