Fully understanding of disclosed embodiment.It will be appreciated, however, by one skilled in the art that can put into practice
The technical scheme of the disclosure and do not have in described specific detail one or more, or can use
Other assembly, step etc..In other cases, it is not shown in detail or describes known features to avoid
The each side of the fuzzy disclosure.
This example embodiment provide firstly a kind of display floater, it include a gate drivers,
One picture element matrix and multiple output buffer.Gate drivers is used for exporting multiple scanning signal；Picture
Prime matrix is formed at the viewing area of array basal plate, electrically connects with this gate drivers, including multirow
The scan line that impedance is incomplete same, receives this scanning signal respectively；Multiple output buffers electricity respectively
Be connected between this gate drivers and this scan line each, gate drivers by output buffer to

Three scan line SL3 connects 6 pixel cells.The impedance of scan line can be with the material of scan line, length
The quantity positive correlation of the pixel cell that degree and scan line are connected.With reference to Fig. 3, in Fig. 3, the 3rd sweeps
The pixel cell quantity retouching the length of line SL3 and connection is all most, and the impedance of therefore equivalence is maximum, the
The impedance of two scan lines SL2 is taken second place, and the impedance of the first scan line SL1 is minimum.Therefore, output buffering
Driving force required by device BUF3 is the strongest, and the driving force of output buffer BUF2 is taken second place, defeated
The driving force going out buffer BUF3 is the most weak, and the driving force of the most each output buffer is connected with it
The impedance positive correlation of scan line.
A kind of conventional phase inverter composition using even level series connection that is achieved in that of output buffer, right
In such output buffer, then can change its driving force by selecting different phase inverters.Example
