The system for displaying image comprises a plurality of pixel structures each of which comprises an organic illuminating element and a pixel drive circuit. The drive method for the organic illuminating element includes: control a data signal to be written from the data line into the storage capacitor in signal enabling period on the scanning line to set a first end voltage of the storage capacitor; control an other scanning line to set a second end voltage of the storage capacitor in signal enabling period on the scanning line; control the drive element to output a current into the organic illuminating element according to the potential difference of the first end and the second end of the capacitor to drive the organic illuminating element illuminating. Advantage: prolonged service life of organic illuminating element.
Description
technical field [0001] The invention relates to a system and a driving method of a light-emitting element, in particular to a system for displaying images and a driving method of an organic light-emitting element. Background technique [0002] Organic Light-Emitting Display (OLED) can be divided into Passive-Matrix OLED (PM-OLED) and Active-Matrix OLED (AM-OLED) according to its driving method. OLED), however, the passive matrix organic light emitting display is limited by the driving mode, and has the disadvantages of short lifespan and incapability of large area, so the active matrix organic light emitting display is more suitable for high-efficiency and large-size display applications. [0003] The active matrix organic light-emitting display mainly includes an organic light-emitting element electrically connected to the pixel driving circuit, the pixel driving circuit is electrically connected to a scanning driving circuit and a data driving circuit, and the pixel drivin...
