The present application provides a display panel and a display device. In the display panel, a first channel is divided into the first sub-channel and the second sub-channel, so that a variation in a width of a channel of a first thin film transistor is greater than a variation in a width of a channel of a second thin film transistor, thereby reducing a variation in the impedance ratio between the second thin film transistor to the first thin film transistor, such that a difference in brightness between a secondary pixel in the sub-pixel unit corresponding to the splicing area and a secondary pixel in the sub-pixel unit corresponding to the non-splicing area reduced, thus improving the problem of the uneven brightness of the display panel.
A display panel, comprising a plurality of sub-pixel units disposed in an array in the display panel, wherein each of the sub-pixel units comprises at least a main pixel electrode, a secondary pixel electrode, a first thin film transistor connected to the secondary pixel electrode, a second thin film transistor connected to the first thin film transistor, and a third thin film transistor connected to the main pixel electrode, wherein the first thin film transistor comprises a first source, a first drain, and a first channel partially disposed between the first source and the first drain, the second thin film transistor comprises a second source, a second drain, and a second channel disposed between the second source and the second drain;
A display device, comprising a device body and a display panel disposed on the device body, wherein the display panel comprises a plurality of sub-pixel units disposed in an array in the display panel, wherein each of the sub-pixel units comprises at least a main pixel electrode, a secondary pixel electrode, a first thin film transistor connected to the secondary pixel electrode, a second thin film transistor connected to the first thin film transistor, and a third thin film transistor connected to the main pixel electrode, wherein the first thin film transistor comprises a first source, a first drain, and a first channel partially disposed between the first source and the first drain, the second thin film transistor comprises a second source, a second drain, and a second channel disposed between the second source and the second drain;
A display device, comprising a device body and a display panel disposed on the device body, wherein the display panel comprises a plurality of sub-pixel units disposed in an array in the display panel, wherein each of the sub-pixel units comprises at least a main pixel electrode, a secondary pixel electrode, a first thin film transistor connected to the secondary pixel electrode, a second thin film transistor connected to the first thin film transistor, and a third thin film transistor connected to the main pixel electrode, wherein the first thin film transistor comprises a first source, a first drain, and a first channel partially disposed between the first source and the first drain, the second thin film transistor comprises a second source, a second drain, and a second channel disposed between the second source and the second drain;
