Patent ID: 8416159

Claim:
A display apparatus comprising a plurality of pixels, a plurality of scan lines electrically connected with the pixels respectively and a plurality of data lines electrically connected with the pixels respectively and a plurality of data line electrically connected with the pixels respectively, each of the pixels comprising: a light emitting unit; a memory circuit for storing an image data; a driving circuit electrically connected with the light emitting unit and the memory circuit, and driving the light emitting unit according to the image data; a mode switching circuit electrically connected with the memory circuit and a mode control line for controlling the driving circuit to drive the light emitting unit according to the image data stored in the memory circuit in a normal mode or a Memory-In-Pixel (MIP) mode, wherein the mode switching circuit comprises: an enabling switch electrically connected with the driving circuit and the memory circuit for controlling the driving circuit to drive the light emitting unit according to the image data stored in the memory circuit in the normal mode or the MIP mode; and a feedback switch electrically connected with the enabling switch and the light emitting unit, wherein when the light emitting unit emits light, the feedback switch is turned on to connect the enabling switch and a bias line; and a switch circuit electrically connected with the memory circuit, one of the scan lines, and one of the data lines, wherein the scan line outputs a scan signal to turn on the switch circuit, so that the image data is written into the memory circuit through the data line in the normal mode, wherein an imbalance leakage current of the switch circuit is larger than that of the mode switching circuit such that the image data stored in the memory circuit is hold by the imbalance leakage currents.
