Problems solved by technology
However, in the holding phase (that is, after the DC voltage signal is stopped to the pixel electrode, the electrophoretic particles continue to move under the action of the potential of the pixel electrode), due to the influence of the own characteristics of the thin film transistors T1 and T2, the large pixel electrode The potential gradually decreases, which affects the movement of electrophoretic particles
In other words, the leakage phenomenon of thin film transistors T1 and T2 will affect the potential required for the movement of electrophoretic particles, thereby affecting the display effect

The embodiment of the present application discloses a pixel driving circuit and a pixel driving method. The pixel drive circuit includes a control unit, a transmission unit and a feedback unit; the control unit includes a first input terminal and a second input terminal, wherein the first input terminal is used to receive the first signal, and the second input terminal is used to receive the control signal; The control unit outputs the first signal to the transmission unit under the control of the control signal; the transmission unit outputs the first potential signal or the second potential signal to the pixel electrode and the feedback unit under the control of the first signal, wherein the first potential signal The polarity of the second potential signal is opposite; the feedback unit outputs a feedback signal to the transmission unit under the control of the first potential signal or the second potential signal. The feedback signal in this embodiment can latch the signal output by the transmission unit, so as to realize the effective supply of the potential required by the pixel electrode, so as to meet the display requirement.
Description
technical field [0001] The present application relates to the field of display technology, in particular to a pixel driving circuit and a pixel driving method. Background technique [0002] In recent years, displays have gradually begun to develop in a light and thin direction, and electronic paper displays have become a display that meets the needs of the public. It has the characteristics of low power consumption, delicate picture display, and wide viewing angle. [0003] The electronic paper display controls the displacement of electrophoretic particles through the electric field, and then controls the reflection of light, so as to realize the display of the required picture. Since the movement of electrophoretic particles is based on the electric field, the electronic paper can last for a long time (such as 1 month) after the power is removed. In addition, the electronic paper display belongs to the static diffuse reflection mode, and its display effect is very close t...
