Description
Technical field
The present invention relates to the technical field of liquid crystal display, it is specifically related to a kind of liquid crystal display panel, array substrate and its has
Balance the dot structure of farmland area.
Background technique
TFT-LCD (ThinFilmTransistorLiquidCrystalDisplay, thin film transistor liquid crystal display) face
One important evaluation index of plate is the penetrance of panel, particularly with the high-resolution panel of large scale, high penetrance
Contrast, the power consumption for reducing backlight can be improved.A key factor for influencing penetrance is the aperture opening ratio of panel pixel, is improved
Aperture opening ratio can improve penetrance from the angle of design.
Aperture opening ratio refers to the ratio of effective transmission region and entire area, refers generally to the wiring for removing each sub-pixel
Light after portion, tTransistor portion (generalling use black matrix" to hide) passes through the area of part and the face of each sub-pixel entirety
Ratio between product.Aperture opening ratio is higher, and the efficiency that light passes through is higher.When light is emitted via backlight, it is not
All light can pass through panel, such as connection LCD source driving chip and the signal wire of grid drive chip and thin
Film transistor (TFT) itself, there are also storage capacitors of stored voltage etc..These are local other than incomplete light transmission, also due to
It is not controlled by voltage by the light in these places, and can not show correct grayscale, so all needing to be subject to using black matrix"
Masking, in order to avoid interfere other transmission regions.
In dot structure in the prior art, to increase aperture opening ratio, Cst (crystal oscillator) is formed using pixel ITO and gate
The structure of on gate realizes the storage capacitance of pixel, or directly removes Cst.Fig. 1 is Cst on gate in the prior art
A kind of conventional design schematic diagram.
It will be noted from fig. 1 that because of the presence of TFT (thin film transistor (TFT)) 11 in (farmland) Domain 1 in dot structure
, the aperture opening ratio (S1) in the area upper left corner is occupied, the Via hole (via hole) 31 of Domain 3 is similarly accounted in the lower right corner
With aperture opening ratio (S2), since S1 is greater than S2, the aperture opening ratio size that twoth area occupy is simultaneously unequal, therefore leads to Domain 1
With the difference of the aperture opening ratio of Domain 3.
