Embodiment Construction

[0022] Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like numerals represent like elements throughout. The following embodiments for explaining the present invention will be described with reference to the accompanying drawings.

[0023] The basic scheme of the present invention is to use the anode and cathode layers of the OLED device as the electrode layer of the touch sensor, that is, the cathode is patterned and then used as the sensing electrode Rx of the sensing layer of the touch sensor, and is arranged on the substrate in conjunction with the touch sensor. At least one touch drive electrode set on the same layer as the anode is used as the drive electrode Tx of the touch sensor; and then the OLED drive operation and touch sensing operation are performed through time-sharing driving to complete this integrated in-cell touch display touch and display operations. The s...

Abstract

The invention provides an OLED touch control substrate. The OLED touch control substrate comprises a substrate body, an anode arranged on the substrate body, a cathode arranged on the substrate body and at least one touch control drive electrode. The anode comprises a plurality of sub-anodes. The cathode comprises a plurality of sub-cathodes. The touch control drive electrodes are arranged on the substrate body and are located on the same layer as the anode. The touch control drive electrodes are insulated from the cathode. The sub-cathodes are arranged in an intersected mode. At the display stage, display drive signals are applied to the cathode and the anode and used for driving OLED light-emitting devices. At the touch control state, touch control drive signals are applied to the touch control drive electrodes, and the sub-anodes are used as touch control sensing electrodes to output touch control induction signals. The invention further provides a display device with the OLED touch control substrate and a drive method of the display device. The anode layer and the cathode layer of the OLED device are used as electrode layers of touch control, touch control and display of a touch control display screen are achieved through time-share drive, the electrode layers are saved, and lighter and thinner touch control displays can be manufactured.

Description

technical field [0001] The present invention relates to the display field, in particular to a touch substrate, a display device, a manufacturing method and a driving method thereof. Background technique [0002] Active Matrix / Organic Light Emitting Diode AMOLED (Active Matrix / Organic Light Emitting Diode) is an active matrix organic light emitting diode panel. Compared with traditional liquid crystal panels, AMOLED has attracted much attention because of its advantages such as fast response speed, high brightness, low power consumption, good viewing angle, and flexible display. At present, small and medium-sized AMOLED displays mostly adopt on-cell touch (On-cell touch) technology. Compared with the on-unit touch technology, the AMOLED in-cell technology has gradually attracted attention because it can make the display module thinner and lighter. [0003] Most of the AMOLED embedded solutions that have been reported are to make the sensor under the package substrate, but t...
