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 invention discloses a pixel driving circuit and a pixel driving method. The pixel driving circuit comprises a control unit, a transmission unit and a feedback unit; the control unit comprises a first input end and a second input end, wherein the first input end is used for receiving a first signal, and the second input end is used for receiving a control signal; under the control of the control signal, the control unit outputs the first signal to the transmission unit; under the control of the first signal, the transmission unit outputs a first potential signal or a second potential signal to a pixel electrode and the feedback unit, wherein the polarity of the first potential signal is opposite to that of the second potential signal; under control of the first potential signal or the second potential signal, a feedback signal is output to the transmission unit. The feedback signal can lock the signal output by the transmission unit to achieve effective supply of the potential needed by the pixel electrode, and therefore the displaying requirement is met.
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...
