Description
Technical field
The present invention relates to liquid crystal display panel field more particularly to it is a kind of for half source drive pixel array liquid
The measurement circuit of LCD panel.
Background technique
In liquid crystal display panel production process, it generally can all carry out once being powered on the test lighted, to detect liquid crystal picture
Whether element display is normal.It is main using test stub (Shorting bar) in the technology of existing liquid crystal display panel test detection
The mode of panel wiring is tested, and the test stub is exactly the face for being shorted independent gate signal or data-signal
Plate region, the various exceptions that LCD display intralamellar part occurs, can theoretically be detected by this test at this station
Come, it should guarantee to be tested to each sub-pixel offer signal.
As shown in Figure 1, Fig. 1 shows a kind of structural schematic diagram of typical liquid crystal display panel LCD array substrate, the array
Substrate includes viewing area 10 and the peripheral region 11 positioned at 10 periphery of viewing area.
A plurality of orthogonal data line Dm and grid line Gn, each data line Dm and grid line are provided in viewing area 10
Gm infall connects a sub-pixel 14.The peripheral region 11 is provided with the first test stub 15 and public electrode wire 16, institute
It states and is provided with danger signal line R, green line G on the first test stub 15 and blue signal line B (corresponds respectively to RGB
The test of R/G/B), the data line Dm connecting with red sub-pixel is connected to danger signal line R, connect with green sub-pixels
Data line Dm is connected to green line G, and the data line Dm connecting with blue subpixels is connected to blue signal line B, red
Chrominance signal line R, green line G and blue signal line B are used to that data line to occur to the data line Dm to test signal, the public affairs
Common-battery polar curve 16 is used for each sub-pixel 14 into viewing area 10 and provides public electrode；The second survey is additionally provided in the peripheral region
Stub 18 is tried, the second test stub 18 is provided with a plurality of grid line p-wire 19, connects respectively with grid line Gn each in viewing area 10
It connects, tests signal for grid line to occur to the grid line Gn, be by the first test stub 15 and the second test stub 18
Sub-pixel 14 can be lighted, when the first test stub 15 provides R signal and the second test stub 18 is opened, all sub- pictures of red
Vegetarian refreshments is bright, and when the first test stub 15 provides Gn signal and the second test stub 18 is opened, all green sub-pixels are lighted, when
When first test stub 15 provides B signal and the second test unlatching of stub 18, all blue subpixels are lighted, to detect liquid crystal
Whether pixel shows defective.
The resolution ratio of TV panel is higher and higher at present, and screen size is certain, and resolution ratio is higher, and data line is immediately also increasingly
More, data line is more, required COF (the Chip on Film flip introduced external data signal in liquid crystal display panel
Film) quantity is also more and more, and the pin of COF has the certain amount upper limit, the distance between COF and COF are also required to enough
