Problems solved by technology

[0005] The traditional method adopts peripheral IC design, which is not conducive to narrow frame and low cost
[0006] Different panels require different compensation cycles, so the number of Scan signal pulses is not fixed

Embodiment Construction

[0029] The present invention will be fully described below with reference to the accompanying drawings showing embodiments of the invention. However, this invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. In the drawings, components are exaggerated for clarity.

[0030] The transistors used in all embodiments of the present disclosure may be thin film transistors or field effect transistors or other devices with the same characteristics. In this embodiment, the connection manners of the drain and the source of each transistor can be interchanged, therefore, there is actually no difference between the drain and the source of each transistor in the embodiments of the present disclosure. Here, only to distinguish the two poles of the ...

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an adaptive multi-pulse programmable gate drive circuit in OLED display technology, and to a GOA (Gate driver On Array, integrated gate drive circuit) unit and a display device. Background technique [0002] At present, there are many kinds of backplane technology in the display industry, such as a-Si, LTPS, Oxide oxide, etc. Among them, a-Si is easy to manufacture, but its mobility is low and its stability is not ideal. LTPS has good stability, but its cost is relatively high. , and the uniformity is poor, and it is not suitable for the manufacture of large-size panels. IGZO (Indium Gallium Zinc Oxide) is widely used in large-size OLED products due to its high mobility, good uniformity and low cost. [0003] The uniformity of AMOLED light emission is affected by Vth, and a compensation Vth circuit will be added in the pixel design. [0004] The internal compensation o...
