Abstract:
The invention provides a GOA driving circuit, comprising: a plurality of GOA units connected in cascade, each GOA unit comprising a pull-up control module (1), a pull-up module (2), a pull-down module (3), a first pull-down maintenance module (4), and a second pull-down maintenance module (5); on the basis of ensuring the normal function of the GOA unit, the pull-down module (3) uses one less TFT than the prior art, the first pull-down maintenance module (4) uses one less TFT than the prior art, the second pull-down maintenance module (5) uses one less TFT than the prior art, thereby saving the wiring area used by GOA driving circuit and facilitating the narrow border LCD. The invention provides an LCD using the GOA driving circuit. Therefore, the number of the TFTs of the GOA driving circuit is less, the wiring area is smaller, and the LCD border is narrower.
