Description
Technical field
The present invention relates to display panel, and particularly relevant for a kind of liquid crystal display.
Background technology
Display panel can be divided into two kinds of horizontal-scroll-type and portrait formulas according to its use-pattern.And when display panel was connected with the driving chip, the pin arrangement meeting that drives chip was the difference of horizontal-scroll-type or portrait formula according to panel, and different arrangement design is arranged, and drove chips to adapt to horizontal-scroll-type and portrait formula panel therefore have traditionally two kinds.
Mode when being illustrated in figure 1 as horizontal-scroll-type panel 1 and driving chip 10 and is connected is welded on the left of panel or the right side and drive chip 10.Gate line 21 cablings of horizontal-scroll-type panel are horizontal direction, wherein G1, G2～G800 represent respectively the 1st to the 800th gate line, source electrode line 22 cablings are vertical direction, wherein S1, S2～S1140 represent respectively the 1st to the 1140th source electrode line, and R, G, B represent respectively three kinds of different pixels of red, green, blue.Drive chip 10 in order to coordinate the cabling mode of horizontal-scroll-type panel 1 gate line 21 and source electrode line 22, the output pin 77 of gate line drive circuit must be arranged in the middle body that drives chip 10, the output pin 75,77 of source line driving circuit is arranged in the two ends up and down that drive chip 10.So the arrangement that the gate line driving block of driving chip 10 inside and source electrode line drive block just as shown in Figure 1, be respectively that source electrode line drives block 65, gate line driving block 67, source electrode line driving block 66 from top to bottom.
The mode that is portrait formula panel 1 as shown in Figure 2 when driving chip 10 and be connected.Gate line 21 direction of routing of portrait formula panel are not identical with the panel of source electrode line 22 direction of routing and horizontal-scroll-type.Its gate line 21 cablings of portrait formula panel are vertical direction, wherein G1, G2～G800 represent respectively the 1st to the 800th gate line, source electrode line 22 direction of routing are horizontal directions, wherein S1, S2～S1140 represent respectively the 1st to the 1140th source electrode line, and R, G, B represent respectively three kinds of different pixels of red, green, blue.Driving chip 10 remains and is welded in panel upper left side or right side.Drive chip 10 and drive chip 10 Shang Xia two ends for coordinating the gate line 21 and source electrode line 22 cabling modes of portrait formula panel, gate line driver output pin 71,72 must being arranged in, source electrode line 22 driver output pin are to be arranged in driving chip 10 central authorities.So, the arrangement that the gate line driving block of driving chip 10 inside and source electrode line drive block just as shown in Figure 2, be respectively that gate line drives block 61, source electrode line drives block 63, gate line driving block 62 from top to bottom, be connected with portrait formula panel with convenient.
By above-mentioned prior art as can be known, driving chip must have two kinds at least, coordinates different gate lines to drive block and source electrode line driving block arrangement and different pin arranging mode, to meet the different demands of horizontal-scroll-type and portrait formula panel.
Summary of the invention
The object of the present invention is to provide a kind of driving chip, and drive block and corresponding pin arranging mode thereof by its internal gate line driving block and source electrode line, make single driving chip can be applicable to simultaneously horizontal-scroll-type and portrait formula panel.This drives chip internal and two above gate lines are set drive blocks and drive block with source electrode line, with and corresponding output pin, and drive at two source electrode lines and place a gate line driving block between block.When this driving chip is connected with panel, the demand according to horizontal-scroll-type or portrait formula panel is different, just some gate lines can be driven the output pin suspension joint of block, and the output pin that gate line that will be suitable drives block and suitable source electrode line driving block is connected to panel.So, single driving chip just can be applicable to horizontal-scroll-type and portrait formula panel simultaneously.
In preferred embodiment of the present invention, above-mentioned panel can be the mode that adopts grid array (Gate on array, GOA) to drive, and the driving of the gate line in above-mentioned driving chip block can be grid array (GOA) driving circuit block.Therefore, in driving chip, the arrangement that grid array (GOA) driving circuit block and source electrode line drive block is to be sequentially from top to bottom: first grid array drive circuit block, the first source electrode line drives block, second grid array drive circuit block, the second source electrode line drives block, the 3rd grid array driving circuit block.
Another object of the present invention is to save the cost of development that drives chip, drive chip supplier and only need develop a kind of driving chip, a cover mask just can be applicable to horizontal-scroll-type or portrait formula panel simultaneously.Being different from traditional approach needs two kinds to drive chip, two cover masks.
The present invention's another purpose is again simplifying panel volume production flow process, and the selection of driving chip only has a kind of, and no longer needing according to panel is that horizontal-scroll-type or portrait formula are selected different driving chips.
The present invention discloses a kind of liquid crystal display, comprising: a panel comprises: gate line, source electrode line and at least one grid array; And one drive chip and be connected to this source electrode line and this at least one grid array, comprising: at least two grid array driving circuit blocks and at least two source line driving circuit blocks; Each these grid array driving circuit block corresponds to one group of output pin; Each these source line driving circuit block corresponds to one group of output pin, wherein, at least one in these grid array driving circuit blocks is arranged between these two source line driving circuit blocks, and at least one in these source line driving circuit blocks is arranged between these two grid array driving circuit blocks.
Beneficial effect of the present invention is: the present invention drives the output pin of chip and corresponding driving circuit block by arrangement, just can reach single and drive chip with regard to the purpose of applicable horizontal-scroll-type and portrait formula panel.The present invention has also saved simultaneously the cost of development that drives chip, drives chip and sends out the business and only need develop a kind of driving chip and just can be applicable to simultaneously horizontal-scroll-type and portrait formula panel.Being different from traditional approach needs two kinds to drive chip, and two cover masks have increased the cost that drives chip.
For above and other purpose of the present invention, feature and advantage can be become apparent, preferred embodiment cited below particularly, and coordinate appended accompanying drawing, be described in detail below.
