Abstract: The disclosure discloses a display panel, a method for compensating for the same, and a display device. The display panel includes a primary driver chip and at least one slave driver chip, each of which includes a gamma circuit; a processing circuit; and signal collectors on respective driver chips, configured to acquire current voltage at corresponding binding points of respective gamma circuits. The processing circuit is configured to compare current voltage at corresponding binding points of respective gamma circuits on respective slave driver chips with current voltage at a corresponding binding point of a gamma circuit on the primary driver chip, and to compensate for voltage to be output at the corresponding binding points of the respective gamma circuits on the respective slave driver chips according to comparison results so that current voltage at the corresponding binding points of the respective gamma circuits on the respective driver chips are same.

Abstract: A force touch device, a force touch feedback method and a touch display device are provided. The force touch device includes a first region and a second region, and further includes: a force detecting electrode in the first region and the second region; a sensing electrode in the first region; an auxiliary electrode in the second region, and the auxillary electrode and the sensing electrode are on a same side of the force detecting electrode. The sensing electrode and the force detecting electrode are disposed oppositely and insulated from each other to form a first force sensor, the auxiliary electrode and the force detecting electrode are disposed oppositely and insulated from each other to form a second force sensor, and a distance of the auxiliary electrode from the force detecting electrode is greater than a distance of the sensing electrode from the force detecting electrode.
