Embodiment 1
[0055] figure 2 For a schematic block diagram of a pixel driving circuit provided by an embodiment of the present invention, please refer to figure 2 , the pixel driving circuit provided by the embodiment of the present invention includes: a compensation unit and a plurality of light-emitting units 1, figure 2 Taking two light-emitting units 1 as an example to illustrate, of course, the number of light-emitting units 1 in the present invention can also be more than three; a plurality of light-emitting units 1 are connected to the same data line data but are figure 2 The first scan line and the second scan line are connected in one-to-one correspondence, that is, the light-emitting unit 1 is connected to the scan line in a one-to-one correspondence; each light-emitting unit 1 includes: an input module 10, a driving module 11, a light-emitting module 12, and a storage module 13 , a first node A, a second node B and a third node C; the compensation unit 2 includes: a first r...
Embodiment 2
[0088] Based on the same inventive concept, an embodiment of the present invention provides a driving method for the pixel driving circuit provided in the above-mentioned Embodiment 1, including a reset step, a data writing and discharging step, and a compensation lighting step; wherein
[0089] In the reset step, the first reset module provides the signal on the first power line to all the second nodes under the control of the signal on the first control line; the second reset module provides the signal on the second control line The signals on the third power line are provided to all the third nodes under the control of the third node; all the storage modules are charged under the control of the signals on the third node and the second node.
[0090] In the data writing and discharging step, valid signals are sequentially input on a plurality of the scan lines, and the first reset module disconnects the first power line and all the first power lines under the control of the s...
Embodiment 3
[0095] An embodiment of the present invention further provides a display device, and the display device includes the pixel driving circuit provided in Embodiment 1 of the present invention. The principle of solving the problem of the display device is similar to that of the aforementioned pixel driving circuit, so the implementation of the display panel can refer to the implementation of the aforementioned pixel driving circuit, and the repetition is not repeated here.
[0096] During specific implementation, the display device provided by the embodiment of the present invention may be any product or component with display function, such as a mobile phone, a tablet computer, a television, a monitor, a notebook computer, a digital photo frame, and a navigator.
