Embodiment Construction

[0026] see figure 1 , which shows a schematic diagram of the principle of a layout structure of a shift register circuit proposed in an embodiment of the present invention. Such as figure 1 As shown, the shift register circuit 10 includes: shift registers SR(1), SR(2), SR(3)...SR(n-2), SR(n-1), SR(n), signal The traces 121 , 123 and the bus lines 111 , 113 arranged parallel to each other; wherein n is a positive integer greater than 1. Here, the shift register circuit 10 can be applied to an array gate-type gate drive circuit of a display, but the present invention is not limited thereto, and it can also be applied to other drive circuits such as chip-type gate drive circuits or Chip-type source driver circuits, etc.

[0027] Based on the above, each shift register SR(1), SR(2), SR(3)...SR(n-2), SR(n-1), SR(n) in this embodiment all receive clock Signals XCK and CK, and every two adjacent shift registers SR(1), SR(2), SR(3)...SR(n-2), SR(n-1), SR(n) share one signal routi...

Abstract

The invention relates to a layout structure for shift buffer circuits, which comprises a first shift buffer and a second shift buffer arranged adjacent to the first shift buffer. A first signal and a second signal are received by the first shift buffer and the second shift buffer. The second signal and the first signal are reversed phases to each other. In addition, the first shift buffer and the second shift buffer share the signal line so as to receive the first signal. The shared signal line extends between the first shift buffer and the second shift buffer.

Description

【Technical field】 [0001] The invention relates to the technical field of semiconductor manufacturing process, and in particular to a layout structure of a shift register circuit. 【Background technique】 [0002] Press, flat-panel displays such as liquid crystal displays are widely used in consumer electronics products such as mobile phones, notebook computers, desktop displays, and televisions due to their advantages of high image quality, small size, light weight, and wide application range, and have been Gradually replace the traditional cathode ray tube (CRT) display and become the mainstream of the display. [0003] In the liquid crystal display panel, a gate drive circuit and a source drive circuit are provided to respectively provide a gate drive pulse signal and a display data signal, thereby achieving the purpose of image display. In the gate driving circuit and the source driving circuit, a shift register circuit is usually provided for shifting and temporarily stor...
