The invention discloses a touch flat-panel display, which comprises a display screen, a display driving circuit, a touch detection circuit and the like. Related circuits in the touch flat-panel display enable a display screen electrode to transmit a display driving signal and a touch signal, and the flat-panel display can be used for normal display and used for realizing touch detection through adisplay driving and touch detection multiplexing display screen electrode. By applying touch signals to a detected electrode and a non-detected electrode at the same time, the flow of the touch signals between the detected electrodes and between the detected electrode and the non-detected electrode is reduced, the flowing direction of the touch signals is controlled, and the accuracy of judgment on the touched electrodes is improved. By applying the touch signals to a plurality of groups of detected electrodes at the same time and respectively detecting the changes of the touch signals flowing through the groups of detected electrodes, less time is required for detecting touch points of the whole display screen.

The invention discloses a touch screen, comprising touch detection circuit, sensing electrodes able to be coupled with touch object, and touch detection electrodes connected with the touch detection circuit, where the number of touch detection electrodes is less than that of sensing electrodes, the touch detection electrodes can be coupled with the sensing electrodes, the touch detection circuit is used to detect and compare signals on the touch detection electrodes as touch does not happen and as touch happens. And it can only detect a small number of touch detection electrodes to be able to find the position of the touch object. And it largely reduces requirements for detection technique, and its circuit structure is simple, beneficial to improving the accuracy and reducing the cost and shortening the time for touch locating detection.

The invention relates to a touch display apparatus. The touch display apparatus comprises a first substrate, a second substrate, a touch layer and a touch driver circuit, wherein the second substrate is arranged opposite to the first substrate; at least one part of the touch layer is arranged on the first substrate; and the touch driver circuit is arranged on the edge of one side of the first substrate and connected with at least one part of the touch layer.

The invention discloses a touch smectic-phase liquid crystal display which comprises a first base body layer and a second base body layer. A mixing layer is arranged between the first base body layer and the second base body layer, a first conductive electrode layer is arranged on the side facing the mixing layer, of the first base body layer, a second conductive electrode layer is arranged on the side facing the mixing layer, of the second base body layer, the first base body layer and the second base body layer each consists of multiple displaying electrodes and multiple touch electrodes, the displaying electrodes are connected with a displaying controller, the touch electrodes are connected with a touch controller, all displaying electrodes of the first conductive electrode layer and all displaying electrodes of the second conductive electrode layer form a pixel point array for multi-stable displaying, and all touch electrodes of the first conductive electrode layer and all touch electrodes of the second conductive electrode layer form a sensing point array for sending touch. Under the condition that a touch panel is not arranged, the touch smectic-phase liquid crystal display has multi-stable displaying and touch functions and is light, thin, free of interference and good in displaying effect.
