Abstract
A display panel, a display device and a driving method are provided. The display panel comprises a touch control driving electrode array including a plurality of touch control driving electrodes; a touch control sensing electrode array including a plurality of touch control sensing electrodes; a force sensing electrode array disposed in a same layer as the touch control sensing electrode array; and at least one force sensing reference electrode. An orthogonal projection of a touch control sensing electrode onto the touch control driving electrode array is at least partially overlapped with the touch control driving electrodes. The force sensing electrode array includes a plurality of force sensing electrodes electrically insulated from the touch control sensing electrodes. An orthogonal projection of the at least one force sensing reference electrode onto the force sensing electrode array is at least partially overlapped with the force sensing electrodes.
