Detailed description of the invention
In order to be more clearly understood from the technical characteristic of the present invention, purpose and effect, now compare accompanying drawing
Describe the detailed description of the invention of the present invention in detail.
Refer to Fig. 2, which is the circuit diagram of the embodiment of the antimierophonic narrow border display of the present invention.Such as figure
Shown in, the 13rd, display 20 comprises control circuit the 11st, multiple first drive circuits the 22nd, multiple second drive circuits
Source electrode drive circuit the 14th, viewing area the 16th, multiple pixel transistors 17.Control circuit the 11st, the second drive circuit
13 control viewing area 16 with source electrode drive circuit 14, so that viewing area 16 shows a picture, wherein, second drives
Dynamic circuit 13 is gate driver circuit (gate driver).First drive circuit 22 has the first driving crystal
Pipe M22, the first driving transistor M22 have the first area B, and it is brilliant that the second drive circuit 13 has the second driving
Body pipe M13, the second driving transistor M13 have second area D.Second area D is more than the first area B.
Furthermore, control circuit 11 couples with the first drive circuit 22, and exports initial signal VST to first
Drive circuit 22, the first drive circuit 22 is after control circuit 11 receives initial signal VST, according to initial letter
Number VST output one driving signal DRI to second drive circuit 13, to drive the second drive circuit 13.Second drives
Dynamic circuit 13 is according to driving signal DRI output scanning signal to multiple pixel transistors 17, to control multiple picture
Cellulose crystal pipe 17.In other words, the second drive circuit 13 is brilliant via multiple pixel of scan line control viewing area 16
The conducting of body pipe 17 and cut-off, to show picture.Source electrode drive circuit 14 couples multiple pixel transistor 17
And export and multiple display signal to viewing area 16, so that display 20 shows picture.
Referring again to Fig. 2, in order to reach the requirement of narrow frame, the present invention is peripheral in viewing area 16, i.e. non-
Viewing area, is not provided with pixel load 15 (Fig. 1), and such present invention compares in the scope using frame region C
Significantly reduce in having in the scope using frame region A of display common in the art.Furthermore, this
First drive circuit 22 of invention does not couples viewing area 16, and does not controls multiple pixel transistor 17, so the
One drive circuit 22 is an empty gate driver circuit (Dummy gate driver) and will not export scanning letter
Number to viewing area 16.First drive circuit 22 is as the buffer circuit of the second drive circuit 13, so via
Initial signal VST that one drive circuit 22 buffer control circuit 11 is exported, the second drive circuit 13 output
The characteristic of scanning signal is more uniform.

The area of the first driving transistor M22 of the first drive circuit 22 is reduced, and the first driving transistor M22
Mainly as the effect of discharge and recharge, so the area of the first driving transistor M22 reduces, the reduction to noise
Have significant effect.Wherein, the area of the first driving transistor M22 is the face of the second driving transistor M13
Long-pending 33%～66%.
Additionally, the area of the first driving transistor M22 reduces and can have significant effect to the reduction of noise,
When reason is that the area of the first driving transistor M22 reduces, the first parasitic electricity of the first driving transistor M22
The capacitance held also and then diminishes.In like manner, the first driving transistor M22 has the first parasitic capacitance, and second
Drive transistor M13 also to have the second parasitic capacitance, and the capacitance of the first parasitic capacitance can be less than second
The capacitance of parasitic capacitance.Such present invention reduces the impact on scanning signal for first parasitic capacitance.
Refer to Fig. 3, which is the embodiment of the gate driver circuit of the antimierophonic narrow border display of the present invention
Circuit diagram.First, accept the area that the invention described above is by the first driving transistor M22 to reduce, and drop
The impact on output OUT (n) for first parasitic capacitance of low first driving transistor M22.Furthermore, the such as the 3rd
First drive circuit 22 shown in figure more can design the 221st, antinoise unit the 222nd, the electric discharge of one scan unit
Circuit 223 and a capacitor Cb, and first drive circuit 22 of the present invention is used for simple scanning or two-way sweeps
The display 20 retouched, and promote antinoise effect.
Additionally, when simple scanning or bilateral scanning, the first drive circuit 22 more can receive forward signal
Vddf, the first initial signal VST1, reverse signal Vddr, the second initial signal VST2 and frequency signal Clk
Etc., the present invention does not limit the application of the first drive circuit 22, and the present invention is to the first driving transistor M22
Area reduce and reduce the technological thought of influence of noise, can be applied equally to other field, for example: electricity
Source class or controller etc., so embodiments of the invention are only using field of display as explanation, not limit
The technological thought determining the present invention is simply possible to use in field of display.
Refer to Fig. 4, showing of embodiment when which is the antimierophonic narrow border display simple scanning of the present invention
It is intended to.As it can be seen, display 20 also comprises the 3rd drive circuit 24, the 3rd drive circuit 24 drives with first

13 simple scanning viewing areas 16, the 3rd drive circuit 24 and the first drive circuit 22 are all arranged at the second driving electricity
The first side H1 on road 13, and the 3rd drive circuit 24 is connected second with the first drive circuit 22 in the first side H1 and drives
Dynamic circuit 13, using the buffer circuit as the second drive circuit 13.Additionally, the 3rd drive circuit 24 and first
Drive circuit 22 also can be arranged at the second side H2 of the second drive circuit 13, and it can also reach simple scanning
Running.Therefore, above-mentioned be only that explanation simple scanning when drive circuit the 22nd, 24 position that can arrange,
And non-limiting present invention driver circuit the 22nd, 24 position is set.
Refer to Fig. 5, which is the signal of embodiment when inventing antimierophonic narrow border display bilateral scanning
Figure.As it can be seen, display 20 also comprises the 4th drive circuit 25, the 4th drive circuit 25 and the 3rd drives
Circuit 24 is all empty gate driver circuit, and right the present embodiment is only with the 4th drive circuit 25 replacement the 3rd driving
Circuit 24 is as the explanation of bilateral scanning embodiment.When display 20 bilateral scanning E, F viewing area 16, the
One drive circuit 22 is arranged at the first side H1 of the second drive circuit 13, and the 4th drive circuit 25 is arranged at second
Second side H2 of drive circuit 13, during such second drive circuit 13 bilateral scanning E, F, the first drive circuit
22 and the 4th drive circuit 25 respectively can be as the buffer circuit of the second drive circuit 13, to reduce noise pair
The impact of scanning signal.
