Abstract

The embodiment of the invention provides a driving substrate and a display panel. The driving substrate comprises a plurality of driving units, and each driving unit comprises two electrodes; and at least one of the two electrodes comprises a protruding part, and the protruding part protrudes from the electrode where the protruding part is located to the other electrode. By means of the design of the protruding parts, the locating positions of LEDs can be controlled when the LEDs are transferred and aligned, so that the transferring and aligning precision of the LEDs can be improved, it is guaranteed that the number of the LEDs aligned to the driving units after transferring and aligning is the same with the preset aligning number, and it is guaranteed that the light-emitting efficiency of all pixels is basically the same.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a driving substrate and a display panel. Background technique [0002] Light-emitting diodes (LEDs), as a light-emitting device, are widely used in the display field. LEDs can not only be used as a backlight source in a liquid crystal display panel, but also smaller-sized LEDs such as micro LEDs and nano LEDs can be used as pixels in a display panel. When an LED is used as a pixel, it is necessary to set a driving substrate to drive it. Due to the limitations of the manufacturing process of LEDs, it is difficult to grow them directly on the driving substrate, so it is necessary to use transfer technology to transfer the manufactured LEDs to corresponding positions on the driving substrate in batches. However, the current transfer technology has the problem of low transfer accuracy leading to inconsistent luminous efficiency among different pixels. Contents of the inv...
