A method of fabricating a pixel structure for use in an electroluminescent panel includes the following steps. A substrate is provided. Three shadow masks having a plurality of first, second, and third openings patterned in an array of T shaped are respectively provided, and three evaporation processes using the three shadow masks are subsequently performed to form a plurality of first subpixel units, second subpixel units and third subpixel units respectively. One first subpixel of the first subpixel unit, one second subpixel of the second subpixel unit adjacent to the first subpixel unit, and one third subpixel of the third subpixel unit adjacent to the first subpixel unit form a display pixel unit.

A full-color organic electroluminescence panel with high resolution comprises a substrate and a plurality of sub-pixel units formed on the substrate. Each sub-pixel unit includes four sub-pixel elements emitting light with the same color. Also, the light color emitted from each sub-pixel unit is different from the light color emitted from the adjacent sub-pixel unit.

A light emitting diode (OLED) display and pixel driving method thereof are disclosed. Each storage capacitor is discharged via the driving TFT and OLED until conductive current of each OLED is almost zero so as to record a sum of a voltage drop across each OLED under a specific condition and the threshold voltage of the driving TFT. By using the sum of the voltage drop across each OLED and the threshold voltage of the corresponding TFT in the subsequent OLED driving process, the luminance reduction issue caused by TFT threshold-voltage shift and OLED material decay can be solved.

A display apparatus comprises a pixel array, a front-end circuit, a test circuit, and an enable circuit. The test circuit tests the pixel array. The enable circuit determines whether to enable the test circuit in response to a predetermined voltage. After the pixel array is tested, the predetermined voltage is provided by the front-end circuit to disable the test circuit.

A driving circuit of display. Two more thin film transistors is added to the original driving circuit of display so that the driving circuit now includes four thin film transistors such that the gate terminal of the thin film transistor's voltage level increases as the threshold voltage of the driving thin film transistor increases. The driving current of the thin film transistor is able to maintain a constant value so that the initial luminance of the display remains unchanged. Therefore, the present invention can effectively increase the average working life of the display.
