Title:
A touch pixel drive circuit, a method, an array substrate, and a liquid crystal display
Document Type and Number:
Japanese Patent JP6192808
Kind Code:
B2
Abstract:
A touch-control pixel driving circuit, a touch-control pixel driving method, an array substrate and a liquid crystal display (LCD) device are provided and involve LCD field, the arrangement of additional driving electrodes and sensing electrodes can be avoided, and the manufacturing process can be simplified, and consequently the costs can be reduced. The touch-control pixel driving circuit comprises a pixel electrode (3), a transmissive common electrode (1), a reflective common electrode (2), a gate line (G1), a reset signal line (G2), a reset control line (G3), a read control line (G4), a dual-purpose data line (G5), a first switching transistor (M1), a second switching transistor (M2), an amplifying transistor (T) and a third switching transistor (M3). Of the first switching transistor (M1), a first end is connected to the pixel electrode (3), a second end is connected to the dual-purpose data line (G5), and a control end is connected to the gate line (G1). Of the second switching transistor (M2), a first end is connected to the reflective common electrode (2), a second end is connected to the reset signal line (G2), and a control end is connected to the reset control line (G3). Of the amplifying transistor (T), a first end is connected to the reset signal line (G2) (G2), and a control end is connected to the reflective common electrode (2). Of the third switching transistor (M3), a first end is connected to a second end of the amplifying transistor (T), a second end is connected to the dual-purpose data line (G5), and a control end is connected to the read data line (G4).
