Abstract: An array substrate and a touch display panel are provided. The array substrate includes a substrate, a pixel unit, a pixel electrode, and a capacitor electrode. An orthographic projection of the capacitor electrode on the substrate at least partially overlaps an orthographic projection of a subpixel electrode on the substrate. By arranging the capacitor electrode in a subpixel area and by making a capacitance value of a storage capacitor corresponding to the subpixel electrode greater than a capacitance value of a storage capacitor corresponding to a main pixel electrode and a common electrode, touch effects of a display panel can be improved.

Abstract: A timing controller is provided. A data enable signal in a timing control module is regenerated by a signal regenerating module. A number of vertical valid display rows is regenerated as a vertical valid display period. A total charge time of all rows of pixels in each frame can be increased effectively. A horizontal blanking period is changed sequentially in a row-by-row manner, thereby compensating charge effects of rows of pixels accurately.

Abstract: A display panel driving method, a display device and a driving device are provided. The method obtains a standard driving voltage value of a target pixel when a subject display content is being displayed and a target compression unit corresponding to the target pixel, determines a target compensation curve parameter from compressed de-Mura data corresponding to the target compression unit according to the standard driving voltage value, determines an effective driving voltage value of the target pixel when the subject content is being displayed according to a position information where the target pixel is in the target compression unit and the target compensation curve parameter, and drives the display panel according to the effective driving voltage. This method could correctly identify the corresponding decompression data and thus the decompressed data could be close to the actual data. This raises the decompression accuracy of decompressing the de-Mura data.

The double-surface display panel comprises a substrate, a plurality of first micro light-emitting diode (LED) units, and a plurality of second LED unis. The first micro LED units and the second LED units are disposed on a same side or different sides of the substrate. A light-emitting direction of the second micro LED units and a light-emitting direction of the first micro LED units are opposite. The first micro LED units and the second micro LED units, which have different light-emitting directions, share the same substrate. Therefore, a thickness of an entire film of the double-surface display panel can be reduced.
