Abstract: A touch driving detection circuit includes a plurality of region driving detection circuits. Each of the plurality of region driving detection circuits includes a control module, a strobe output module, a detection module, a first trigger signal line and a second trigger signal line. The first trigger signal line is configured to input a first trigger signal to the control module to control the strobe output units to output touch scanning signals simultaneously. The detection module is configured to detect whether a touch is present in the touch region and when a touch is present, the detection module triggers the second trigger signal line in the region driving detection circuit to input a primary trigger signal, so that the control module controls the strobe output units to output the touch scanning signals sequentially, thereby determining a location of a touched point in the touch region.

Abstract: A touch display panel is provided with a display area and a non-display area surrounding the display area. It includes an array substrate and a color film substrate arranged opposite to each other. The array substrate includes, in the display area, multiple first touch electrodes extending along a first direction and arranged in sequence along a second direction. The color film substrate includes, in the display area, multiple second touch electrodes extending along the second direction and arranged in sequence along the first direction. A ratio of a coupling capacitance in a direction perpendicular to the array substrate between the first touch electrodes and the second touch electrodes positioned in the display area close to the non-display area to that between the first touch electrodes and the second touch electrodes positioned in the display area far from the non-display area falls in between 0.9 and 1.1.

Abstract: A touch display panel, a driving method and a touch display device are provided. Touch and display are driven synchronously in the touch display panel. That is, touch detection is implemented while the display is performed and there is no need to perform the display and the touch in different stages, thereby avoiding limiting an improvement on a report rate, and ensuring a high report rate of the touch display device.

Abstract: An integrated touch display panel and display device are disclosed. The integrated touch display panel comprises a touch emitting electrode array, a touch sensing electrode array, a black matrix, and color filters. The forward projection of any one of the touch sensing electrodes to the touch emitting electrode array at least partially overlaps with any one of the touch emitting electrodes. The black matrix comprises a plurality of black matrix rows and a plurality of black matrix columns. The color filters are separated by each of the black matrix rows and each of the black matrix columns, to form a plurality of array arrangements of display pixels. The touch sensing electrode is a mesh electrode, and the black matrix at least partially covers an orthogonal projection of the mesh electrodes to the black matrix.

Abstract: The present application discloses an integrated touch control display panel and an integrated touch control display device comprising the same. A specific embodiment of the integrated touch control display panel comprises a plurality of touch control sensing electrodes extending along a first direction and disposed along a second direction. The touch control sensing electrode has a grid structure, and comprises a plurality of electrically connected metal electrodes. The metal electrode comprises a plurality of electrically connected sub-metal electrodes, and the sub-metal electrode has a width of a, wherein a is less than or equal to 3 micrometer (3 μm) and is greater than or equal to 2.5 micrometer (2.5 μm). In this embodiment, the blocking effect of the grid touch control sensing electrodes on the light in a display region is attenuated, and thereby display effect is improved.
