Document Type and Number:
Japanese Patent JP6901544
Kind Code:
B2
Abstract:
A driving circuit, a display panel, and a display device are provided. The display panel comprises a plurality of common electrodes; a plurality of phototransistors, two or more phototransistors among the plurality of phototransistors being disposed in an area corresponding to each of the plurality of common electrodes; a plurality of photo-control lines electrically connected to a gate electrode of at least one phototransistor among the plurality of phototransistors; a plurality of photo-driving lines electrically connected to a first electrode of at least one phototransistor among the plurality of phototransistors, and a plurality of read-out lines, each of the plurality of read-out lines being electrically connected to a single common electrode among the plurality of common electrodes, and electrically connected to second electrodes of all of the phototransistors disposed in the area corresponding to the single common electrode to which each of the plurality of read-out lines are electrically connected. According to the present invention, an increase in non-open areas is minimized and the magnitude of the output signal of the phototransistor detected through the read-out line is increased, thereby improving photosensing performance.
