Problems solved by technology

But the LED1 disconnection causes the brightness loss of single partition
In the above connection mode, when one light-emitting element is disconnected, the luminance of a single partition will be reduced, which will seriously affect the display quality of the whole machine

Embodiment Construction

[0042] The following will clearly and completely describe the technical solution in the application with reference to the accompanying drawings in the implementation manner of the application. Apparently, the described implementations are only some of the implementations of this application, not all of them. Based on the implementation manners in this application, all other implementation manners obtained by those skilled in the art without creative efforts shall fall within the scope of protection of this application.

[0043] In this application, unless otherwise clearly specified and limited, a first feature being "on" or "below" a second feature may include the first and second features directly, or may include that the first and second features are not directly connected but through another characteristic contact between them. Moreover, "above", "above" and "above" the first feature on the second feature include that the first feature is directly above and obliquely abov...

Abstract

The invention provides a light-emitting substrate and a display device. The light-emitting substrate includes a plurality of partitions including a first light-emitting unit and a first standby unit. The first light emitting unit includes at least one light emitting element. The first standby unit is connected in parallel with the first light-emitting unit. The first standby unit comprises a standby light-emitting element, and the working voltage of the first standby unit is larger than that of the first light-emitting unit. The first standby unit of the light-emitting substrate can replace the light-emitting element which is disconnected in the first light-emitting unit to emit light and conduct the circuit, so that dark light or brightness loss caused by disconnection of the light-emitting element in a single partition can be prevented.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a light-emitting substrate and a display device. Background technique [0002] Mini-LED (submillimeter light-emitting diode) and Micro-LED (micro-light-emitting diode) (hereinafter collectively referred to as mLED) display technologies have the advantages of high brightness, high contrast, and long service life. mLED can not only be used as a direct backlight to realize HDR function, but also can be used as a display to realize direct display, transparent display, flexible display and many other functions. [0003] M rows and N columns of partitions are usually arranged on a known mLED light-emitting substrate. In order to improve the brightness and uniformity of each partition, more than two light emitting elements are arranged in each partition. More than two light-emitting elements in each partition are connected in series, in parallel or in series-parallel. Plea...
