摘要： A circuit driving substrate, display panel and a display driving method are provided. The circuit driving substrate includes a pixel array, a first switching circuit, a second switching circuit, a first driving circuit and a second driving circuit. The first switching circuit is coupled to the pixel array through a plurality of gate lines, and receives a first switching signal. The second switching circuit is coupled to the pixel array through the gate lines, and receives a second switching signal. The first driving circuit is coupled to the first switching circuit and configured to output the first voltage signal to the first switching circuit. The second driving circuit is coupled to the second switching circuit and configured to output a second voltage signal to the second switching circuit. The first switching circuit and the second switching circuit selectively provide the first voltage signal or the second voltage signal.

摘要： A display device includes a driving circuit substrate, a display layer, an opposite substrate, and a conducting structure. The driving circuit substrate includes a first substrate and a driving circuit layer disposed on the first substrate. The driving circuit layer includes a display region, a peripheral region at the periphery of the display region, and a conducting pad located between the peripheral region and an edge of the first substrate. The opposite substrate includes a second substrate and an opposite electrode layer disposed on the second substrate. The display layer is located between the opposite electrode layer and the driving circuit layer. A conductive member of the conducting structure is connected between the conducting pad and the opposite electrode layer. The conducting structure has a first width. The peripheral region has a second width. The first width is less than or equal to 2.5 times the second width.
