Abstract

The invention discloses a light-emitting assembly and a light-emitting module. The light-emitting assembly comprises a signal conversion module and a light-emitting unit. The light-emitting unit comprises a first switch module, a light-emitting element and a second switch module, the first end of the first switch module is connected with the signal conversion module, and the second end of the first switch module is connected with the first power supply end; the light-emitting assembly and the second switch module which are connected in series are arranged between the third end of the first switch module and the second power supply end; the signal conversion module is used for converting a target display signal representing image information of a to-be-displayed image block corresponding tothe light emitting unit into a first display signal; wherein the first display signal is used for controlling the third end of the first switch module to output a second display signal in a pulse width modulation form corresponding to the first display signal, and the second display signal is used for controlling the brightness of the light-emitting element under the condition that the scanning end controls the second switch module to be in an on state. The accuracy of brightness control of a light-emitting element can be improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a light-emitting component and a light-emitting module. Background technique [0002] Currently, various display devices for displaying information are being developed. In order to improve the display effect of images, whether it is a backlight light-emitting element in a liquid crystal display or a light-emitting element in a self-luminous display panel, it is necessary to control the brightness (ie, gray scale) of the light-emitting element. [0003] However, the accuracy of controlling the gray scale of the light emitting element is relatively low at present. Contents of the invention [0004] Embodiments of the present invention provide a light-emitting component and a light-emitting module, which can accurately control the brightness of the light-emitting element. [0005] In a first aspect, the present application provides a light-emitting assembly, the light-emitting ...
