A pixel structure of a full-color organic light-emitting diode (OLED) display device comprises a black matrix, a color changing medium, two thin film transistors, a storage capacitor, and an OLED device arranged on a substrate. The pixel structure of the display device uses blue organic light-emitting diodes or polymer light-emitting diodes as electroluminescent media. The low-temperature poly Si (LTPS) thin film transistors provide a current to the OLED device and serve as an active driving device. The color changing medium changes blue light into red or green light to form full-color OLED. The processing steps include the black matrix process, the island process, the gate process, the interlayer process, the color changing medium process, and the OLED deposition process. Because a color changing medium is integrated on the LTPS thin film transistors, this invention can make display devices of high resolution, high luminous efficiency and wide viewing angle.
