Problems solved by technology
[0002] In the field of display equipment, the display panel is prone to Mura phenomenon (a phenomenon in which brightness is uneven and causes various traces) when it is used.
The inventors of the present application have found through research that one of the reasons for the above-mentioned defects is that in the active layer of the display panel, there is a large difference in carrier concentration between certain channel regions, which causes The difference in the performance of thin film transistors leads to the Mura phenomenon in the display panel

The invention provides a display panel, display equipment and a preparation method of the display panel. A substrate and a thin film crystal film layer group are stacked; the thin film crystal film layer group comprises an active layer, an insulating layer and a grid layer which are stacked; the active layer comprises a plurality of channel regions, and the plurality of channel regions are divided into first channel regions with relatively high carrier concentration and second channel regions with relatively low carrier concentration; the first part of the insulating layer is arranged in the first channel regions, the second part of the insulating layer is arranged in the second channel regions, and the thickness of the first part in the insulating layer is greater than that of the second part; and the grid layer comprises a plurality of grids, and the grids are in one-to-one correspondence with the channel regions. According to the display panel, the performance difference between different thin film transistors caused by the difference of the carrier concentration of the first channel regions and the carrier concentration of the second channel regions is greatly reduced, the uniformity of the thin film transistors in the display panel is improved, and therefore the Mura phenomenon is effectively avoided when the display panel is used.
Description
technical field [0001] The present application relates to the field of display technology, and in particular, the present application relates to a display panel, a display device, and a method for preparing a display panel. Background technique [0002] In the field of display devices, the Mura phenomenon (a phenomenon in which brightness is uneven and causes various traces) is prone to occur when the display panel is in use. The inventors of the present application have found through research that one of the reasons for the above-mentioned defects is that in the active layer of the display panel, there is a large difference in carrier concentration between certain channel regions, which causes The difference in the performance of the thin film transistors leads to the Mura phenomenon in the display panel. Contents of the invention [0003] In view of the shortcomings of the existing methods, the present application proposes a display panel, a display device, and a method...
