And the invention can reduce the cost and shorten development time.
Description
[technical field]
The invention relates to a kind of display panels, particularly contain the display panels of the shared panel wires design of two kinds of different LCD drive IC about a kind of inside.
[background technology]
Chip/glass convolution (Chip On Glass, COG) be a kind of LCD (Liquid Crystal Display, LCD) drive integrated circult (Integrated Circuit, IC) packaged type, its mode of utilizing lead to connect (Wire Bonding) is directly fixed on chip on the face glass.And present chip/glass convolution design often needs rewiring because of drive IC is different.Integrate random access memory (Random AccessMemory, in drive IC RAM), different clients is because of the demand difference, some will contain the drive IC of RAM with its application of arranging in pairs or groups; Some then with the drive IC cost for considering, select not contain the drive IC of RAM.And with regard to the LCD exploitation, be necessary for two kinds of LCD wires design of above-mentioned two types of product developments with a kind of resolution.
Please refer to Fig. 1, is a kind of display panels synoptic diagram of prior art.Display panels 10 comprises a substrate 1.This substrate 1 comprises drive IC district 2, many leads 5 and 6.This drive IC district 2 is used to connect the drive IC that does not contain RAM.This drive IC district 2 comprises the input terminal 4 and the lead-out terminal 3 of a plurality of connection drive IC (figure does not show) pin, this input terminal 4 is connected with flexible circuit board (figure does not show) by lead 5, and this lead-out terminal 3 is connected with data line of liquid crystal display (figure does not show) by lead 6.
, be the display panels synoptic diagram of another kind of prior art please together with reference to figure 2.This display panels 20 comprises a substrate 11.This substrate 11 comprises drive IC district 12, many leads 15 and 16.This drive IC district 12 is used to connect the drive IC that contains RAM, liquid crystal display-driving IC for equal resolution, because of its inner structure difference, the chip area of drive IC that contains RAM is generally greater than the drive IC that does not contain RAM, therefore, the area in the drive IC district 2 of this drive IC district 12 in Fig. 1 is big.This drive IC district 12 comprises the input terminal 14 and the lead-out terminal 13 of a plurality of connection drive IC (figure does not show) pin, this input terminal 14 is connected with flexible circuit board (figure does not show) by lead 15, and this lead-out terminal 13 is connected with data line of liquid crystal display (figure does not show) by lead 16.
More than two kinds of wires design be at the different drive IC of a kind of LCD resolution identical function, develop two kinds of display panels wires design, therefore expending cost influences the development time simultaneously.
[summary of the invention]
In order to overcome the drive IC that prior art is identical at LCD resolution, function is different, develop two kinds of display panels wires design and expend the cost impact development time, be necessary to provide a kind of display panels that reduces cost of development and shorten the development time.
A kind of display panels, it comprises a substrate, this substrate comprises a drive IC district, wherein, this drive IC district comprises a plurality of first input end, second input terminal and lead-out terminal, this first input end and lead-out terminal are used to connect the drive IC with first kind of function, this second input terminal and lead-out terminal are used to connect the drive IC with second kind of function, the external circuit of this lead-out terminal and display panels is connected, this first input end and second input terminal electrically connect, and this second input terminal is connected with external circuit.
Compare with prior art, the drive IC district of display panels of the present invention has the input design at the drive IC of two kinds of difference in functionalitys, with in response to different demands, can adopt the identical display panels of wiring when under equal resolution, adopting the drive IC of difference in functionality, therefore reduce cost of development and shorten the development time.

Fig. 2 is the display panels synoptic diagram of another kind of prior art.
Fig. 3 is a display panels synoptic diagram of the present invention.
[embodiment]
Please refer to Fig. 3, is display panels synoptic diagram of the present invention.Display panels 100 comprises a substrate 21.This substrate 21 comprises a drive IC district 22, many leads 25,26 and 28.This drive IC district 22 comprises first input end 24, second input terminal 27 and the lead-out terminal 23 of a plurality of connection drive IC (figure does not show) pin, this first input end 24 and lead-out terminal 23 are used to connect the drive IC that do not contain RAM and identical with the drive IC plot structure that does not contain RAM being connected of prior art and position relation, promptly with Fig. 1 drive IC district 2 in the structure and the position of input terminal 4 and lead-out terminal 3 concern identical.This input terminal 27 and lead-out terminal 23 are used to connect the drive IC that contains RAM and identical with the drive IC plot structure that contains RAM being connected of prior art and position relation, promptly with Fig. 2 drive IC district 12 in the structure and the position of input terminal 14 and lead-out terminal 13 concern identical.This lead-out terminal 23 is connected by the data line (figure does not show) of lead 26 and display panels, connects by lead 28 between this first input end 24, second input terminal 27, and this second input terminal 27 is connected with external circuit by lead 25.
The drive IC that contains RAM reaches the size that the drive IC difference that does not contain RAM or partly contain RAM is its size, and under the LCD resolution same case, the drive IC size that contains RAM is greater than the drive IC size that does not contain or partly contain RAM.As shown in FIG., under identical resolution, contain or partly contain the drive IC of RAM and do not conform to the drive IC that RAM is arranged, all can adopt identical liquid crystal panel wiring, this wiring utilizes first input end 24 and second input terminal 27 different and that connect to connect the input pin of different driving IC respectively, the output pin of different driving IC connects identical lead-out terminal 23, so that different drive IC all can be arranged in this drive IC district 22 to drive liquid crystal panel.Therefore under the identical resolution, the drive IC that contains or partly contain RAM reaches the drive IC that does not contain RAM, and the present invention adopts identical liquid crystal panel wire laying mode can save development time reduction cost of development.
