Abstract

The invention discloses a scanning driving circuit structure and an OLED (organic light-emitting display). The scanning driving circuit structure comprises at least one scanning driver, wherein a scanning signal line is led out of each scanning driver, and at least one scanning amplifying circuit is in series connection with each scanning signal line. The scanning amplifying circuits are added in display areas, so that scanning signals required by pixel circuits in the OLED are enhanced, the scanning signal driving capacity of the scanning drivers in the OLED is significantly enhanced, and various display problems caused by signal delay of the scanning signals of the different display areas are solved. Besides, the circuit structure is simple to implement and low in cost.

Description

technical field [0001] The invention relates to an organic light emitting display technology, in particular to a scan driving circuit structure and an organic light emitting display. Background technique [0002] Active Matrix Organic Light Emitting Diode (AMOLED) display devices are actively light emitting devices. Compared with the current mainstream flat-panel display technology Thin Film Transistor Liquid Crystal Display (TFT-LCD), AMOLED has the advantages of high contrast, wide viewing angle, low power consumption, and thinner thickness. It is expected to become the next-generation flat-panel display technology after LCD. It is one of the most concerned technologies in flat panel display technology. [0003] figure 1 It is a traditional AMOLED pixel driving circuit, including switching transistor T1, storage capacitor Cst, driving transistor T2, organic light emitting diode OLED, power supply Vdd and Vss, scanning signal line Sn, and data signal line Dm. [0004] ...
