Abstract

The invention provides a display control unit of a touch display, the touch display and a control method of the touch display. The touch display comprises a display control unit, a display screen, a touch sensor and a first circuit. And the display screen is connected with the display control unit through a data line. And the touch sensor is arranged on the display screen. And a first circuit connected between the data line and the display control unit. The display control unit is used for controlling the touch sensor to be connected into the first circuit to form a filter circuit when receiving the filter control signal and filtering the signal transmitted by the data line through the filter circuit, and the touch sensor is an equivalent capacitor of the filter circuit. The embodiment ofthe invention can be used for reducing the interference of the signal transmitted by the data line on the touch of the touch display.

Description

technical field [0001] The present invention relates to the field of touch technology, in particular to a display control unit of a touch display, a touch display and a control method thereof. Background technique [0002] Electromagnetic Interference (EMI) refers to the interference caused by electronic products to other surrounding electronic products when they are working, including conduction interference and radiation interference. Conducted interference refers to the coupling of a signal on one electrical network to another electrical network through a conductive medium. Radiated interference refers to the interference source coupling its signal to another electrical network through space. For radiation interference, the source can be found first, and then shielded. However, the shielding solution for conducted interference is relatively tricky. [0003] In a touch display, the data lines (for example, LVDS data lines) connected between the display control unit and ...
