    Abstract: A driving circuit and a driving method, an active pixel sensor, an image sensor, and an electronic device. The driving circuit includes: a reset circuit, a photoelectric sensing circuit, a signal forming circuit, a signal conversion circuit, and a signal output circuit. The reset circuit resets the photoelectric sensing circuit and the signal forming circuit; the photoelectric sensing circuit performs photoelectric conversion on incident light irradiation to form a photoelectric voltage signal; the signal forming circuit transmits the photoelectric voltage signal to the signal conversion circuit, and transmits a compensated photoelectric voltage signal to the signal conversion circuit; the signal output circuit transmits a second voltage to the signal conversion circuit and the signal forming circuit and outputs a photoelectric current signal; the signal conversion circuit forms the compensated photoelectric voltage signal and outputs the photoelectric current signal to signal output circuit.

    Abstract: An in-cell touch panel and a display apparatus are provided. The in-cell touch panel includes a lower substrate (1) and an upper substrate (2) disposed oppositely, a number of self-capacitive electrodes (03) independently of each other and located between the lower substrate (1) and the upper substrate (2), a drive chip (3), and wires (04) being configured to connect the self-capacitive electrodes (03) to the drive chip (3). A number of sub-pixels (01) arranged regularly and data lines (02) located between adjacent twos of columns of sub-pixels (01) exist between the upper substrate (2) and the lower substrate (1), each of the sub-pixels (1) is connected to the drive chip (3) through a data line (05) located on one side of it; two sub-pixels (01) adjacent to each other constitute one pixel, or three sub-pixels (01) adjacent to each other constitute two pixels, so that at least one sub-pixel (01) is shared by adjacent pixels. With the in-cell touch panel, integration of touch control and display can be achieved without adding channels of the drive chip (3), and in turn, cost of the in-cell touch panel is reduced.

    Abstract: An in-cell touch panel and a display device are provided, and the in-cell touch panel includes: an upper substrate and a lower substrate which are opposite to each other; a plurality of separate self-capacitive electrodes arranged in an array and in a same layer; and a plurality of conductive wires respectively connected with the self-capacitive electrodes. Both the conductive wires and the self-capacitive electrodes are arranged at a side, facing the lower substrate, of the upper substrate, or at a side, facing the upper substrate, of the lower substrate; and the self-capacitive electrodes each are provided with a plurality of hollowed-out regions. The in-cell touch panel can improve the touch control sensitivity of the touch panel while ensuring a narrow frame design.
