Abstract: An AMOLED doubled-sided display includes an OLED array layer that includes a plurality of top-emitting OLED units and a plurality of bottom-emitting OLED units arranged alternate with each other to form an array. Each of the top-emitting OLD units and the bottom-emitting OLED units has different thickness for respective anodes and cathodes, to realize the top-emitting characteristics of the top-emitting OLED units and the bottom-emitting characteristics of the bottom-emitting OLED units. As such, by designing an algorithm for a single IC to control image displaying, only a display panel and a control IC are sufficient to achieve double-sided displaying, and ensure an observer standing in front of the display panel will not see mirrored image or directional distorted image, as well as achieve low-cost and quality display result.

Abstract: The present invention provides a liquid crystal display panel. The array test circuit (200) comprises a test control unit including a N type thin film transistor and a P type thin film transistor, wherein one thin film transistor is employed to be the output thin film transistor, and the other thin film transistor is employed to be the voltage stabilization thin film transistor. When the liquid crystal display panel is in the normal display state, the test control signal (ATEN) controls the output thin film transistor to be deactivated and controls the voltage stabilization thin film transistor to be activated so that the voltage difference of the gate and the source of the output thin film transistor is zero. Thus, the leakages on the data lines in the active display area (100) are consistent.

Abstract: A scan driving circuit is provided. The scan driving circuit for driving cascaded scan lines includes a scan driving circuit, a latch module, a driving-signal generation module, an output control module, a high gate voltage source, and a low level gate voltage. The scan driving circuit of the present invention conducts a driving operation for the latch module by a first cascade signal and a second cascade signal, so that a clock signal is not required to be processed with a phase inversion, and thereby the scan driving circuit has less overall power consumption.
