Abstract

The invention discloses a touch display panel and a touch display device. The touch display panel comprises a plurality of touch area groups which are sequentially arranged in a first direction or a second direction; each touch area group comprises at least two sub-touch area groups; each sub-touch area group comprises two touch areas. In a touch detection stage, touch electrodes in the two touch areas in the same sub-touch area group receive touch signals in sequence in the arrangement direction of the touch area groups; a first sub-touch area group and a second sub-touch area group which are adjacently arranged exist in the arrangement direction of the touch area groups, the first sub-touch area group comprises a first touch area close to one side of the second sub-touch area group, and the second sub-touch area group comprises a second touch area close to one side of the first sub-touch area group; The time for the touch electrodes in the second touch area to receive touch signals is earlier than the time for the touch electrodes in the first touch area to receive touch signals. According to the technical scheme provided by the embodiment of the invention, the problem of touch delay can be improved, and the touch detection performance is improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a touch display panel and a touch display device. Background technique [0002] Touch operation is a simple and convenient way of human-computer interaction, and more and more products integrate touch functions into display devices. The existing touch display device includes a plurality of touch electrodes, touch wires electrically connected to each touch electrode one by one, and a touch chip electrically connected to the touch wires, wherein the touch wires are used for The touch scanning signal of the touch chip is transmitted to the touch electrode. With the continuous increase of the size of the touch display device or the continuous improvement of the touch precision, the touch electrodes and the touch traces gradually increase, and the signal pins of the touch chip increase accordingly. [0003] In order to simplify the touch control method, the touch scanning s...
