Light emitting device display circuit and drive method thereof
A driving scheme and pixel circuits therein for active matrix light-emitting device displays are provided. The driving scheme is structured to perform both line selection of and power delivery to the pixels via the same scan-power electrode, as opposed to conventional approach where scanning and drive are performed via separate access lines, thereby allowing more compact pixel design and better utilization of light emitting area. Furthermore, this driving scheme provides a dynamic reference for the active elements in a pixel, creating a different design concept and greater flexibility for pixel circuits. Embodiments of pixel circuits employing this driving scheme are exemplified in this disclosure.
