Abstract

The invention discloses a light emitting component and a light emitting module. The light-emitting assembly includes a signal conversion module and a light-emitting unit, and the light-emitting unit includes a first switch module, a light-emitting element connected in series, and a second switch module; the first end of the first switch module is connected to the signal conversion module, and the second end of the first switch module terminal is connected to the first power supply terminal; the light-emitting component and the second switch module connected in series are arranged between the third terminal of the first switch module and the second power supply terminal; the signal conversion module is used to represent the image to be displayed corresponding to the light-emitting unit The target display signal of the image information of the block is converted into a first display signal; the first display signal is used to control the third terminal of the first switch module to output a second display signal in the form of pulse width modulation corresponding to the first display signal, and the second The display signal is used to control the brightness of the light-emitting element when the scanning end controls the second switch module to be in a conducting state. The accuracy of brightness control of the 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 ...
