Controllable switch selects PMOS tube, and such processor need to only export control signal CTRL all the way, by changing the control signal
The low and high level state of CTRL, the first controllable switch and the second controllable switch can be realized selects a conducting.
Specifically, when the first controllable switch K1 ..., Kx ..., Km select NMOS tube, and the second controllable switch
KK1 ..., KKx ..., KKm is when selecting PMOS tube, processor output controls signal CTRL all the way, passes through driving chip
It is transmitted separately to the grid of NMOS tube and the grid of PMOS tube.When the control signal is high level, NMOS tube saturation conduction,
PMOS tube cut-off, video output DATA by the first controllable switch K1 ..., Kx ..., Km be transmitted to small viewing area 31, control
It makes small viewing area 31 and shows picture.Conversely, when the control signal CTRL is low level, PMOS tube saturation conduction, NMOS tube
Cut-off, video export DATA by the second controllable switch KK1 ..., KKx ..., KKm be transmitted to big viewing area 32, thus just
The big progress of viewing area 32 picture is switched to show.
Similarly, when the first controllable switch K1 ..., Kx ..., Km select PMOS tube, and the second controllable switch
KK1 ..., KKx ..., KKm is when selecting NMOS tube, processor output controls signal CTRL all the way, passes through driving chip
It is transmitted separately to the grid of NMOS tube and the grid of PMOS tube.When the control signal CTRL is low level, PMOS tube saturation
Conducting, NMOS tube cut-off, video export DATA by the first controllable switch K1 ..., Kx ..., Km be transmitted to small viewing area
31, it controls small viewing area 31 and shows picture.Conversely, when the control signal CTRL is high level, NMOS tube saturation conduction,
PMOS tube cut-off, video export DATA by the second controllable switch KK1 ..., KKx ..., KKm be transmitted to big viewing area 32,
To show picture by the big viewing area 32.Thus, it is possible to realize that display picture is seamless between two viewing areas 31,32
Switching, and the picture of the big display of viewing area 32 is twice that small viewing area 31 shows picture, image display quality is guaranteed.

Second half of the cycle is connected in switch Mux2.When due to showing picture by big viewing area 32, the same time only has the pixel of half
It lights, in addition the pixel of half extinguishes, therefore energy consumption when large-size screen monitors display can be significantly reduced, when the continuation of the journey of extending cell phone
Between.
Similarly, in order to save the pin resource of processor and driving chip, the first Time-sharing control switch Mux1 and
Two Time-sharing control switch Mux2 are it is also preferred that carry out circuit design using the opposite metal-oxide-semiconductor of on-off characteristic.
Specifically, when the first Time-sharing control switch Mux1 selects NMOS tube, the second Time-sharing control switch
When Mux2 selects PMOS tube, the driving chip can export the grid that driving signal DRV all the way is transmitted separately to the NMOS tube
The grid of pole and PMOS tube.It is high electricity in half of display cycle before a frame picture that driving chip, which sets the driving signal DRV,
It is flat, m the first Time-sharing control switch Mux1 saturation conductions of control, m the second Time-sharing control switch Mux2 cut-offs；And it is drawn in a frame
The driving signal DRV built in rear half of display cycle in face is low level, and m the first Time-sharing control switch Mux1 of control are cut
Only, m the second Time-sharing control switch Mux2 saturation conductions are achieved in the driving of the timesharing to big viewing area 32.
Similarly, when the first Time-sharing control switch Mux1 selects PMOS tube, the second Time-sharing control switch Mux2 choosing
When with NMOS tube, the driving chip can export driving signal DRV all the way be transmitted separately to the PMOS tube grid and
The grid of NMOS tube.It is low level, control in half of display cycle before a frame picture that driving chip, which sets the driving signal DRV,
M processed the first Time-sharing control switch Mux1 saturation conductions, m the second Time-sharing control switch Mux2 cut-offs；And in a frame picture
The driving signal DRV built in half of display cycle is high level, m the first Time-sharing control switch Mux1 cut-offs of control, m afterwards
Second Time-sharing control switch Mux2 saturation conduction, the display cycle of each frame picture of reasonable set, utilizes the persistence of vision of human eye
Phenomenon reaches energy-saving effect in the case where not influencing user's viewing.
Certainly, the first Time-sharing control switch Mux1 and the second Time-sharing control switch Mux2 can also select on state characteristic
Opposite NPN type triode and PNP type triode carry out circuit design, and the present embodiment is not limited in the above citing.
The case where size for big viewing area 32 is other multiple proportions of the size of small viewing area 31, that is, N=3,
4 ..., then N number of data in each group of data input pin need to only be inputted in the m group data input pin of big viewing area 32
End connects the data line connecting with this group of data input pin by a branch data line respectively, and in each branch data
The Time-sharing control switch for controlling the branch data line on-off is separately connected in line, that is, match for each group of data input pin
Set N number of Time-sharing control switch.Then, the driving chip is designed when controlling the big display of viewing area 32 picture, generates driving letter
