Property, the type of inductive switch pipe is p-type, and the type of display switch pipe is N-type.
In the above-described embodiments, photoelectric sensor 11 is a kind of device for converting optical signals to electric signal, and work is former
Reason is based on photoelectric effect.When photoelectric sensor 11 is irradiated by light, it is equivalent to the photon bombardment photoelectric transfer with certain energy
Sensor 11, photon energy pass to the electronics in photoelectric sensor 11, and corresponding change can occur for its state after electronics obtains energy,
Photoelectric sensor 11 is set to generate corresponding electrical effect.Illustratively, photoelectric sensor 11 is photodiode, when no light,
The electric current very little that photodiode generates, referred to as dark current, when there is illumination, the carrier in photodiode is excited, and produces

T1 is closed state, and the received first clock signal CK1 of first end can not pass through inductive switch pipe T1, no normal direction driving chip
301 output trigger signal Trigger.
When manpower touches dark pixel, due to having blocked the extraneous light for injecting dark pixel, photoelectric sensor 11 is not
Photoelectric current can be generated, but generates the dark current of very little, so that the second end of photoelectric sensor 11 exports low level signal, this is low
Level signal is transmitted to the control terminal of inductive switch pipe T1.Due to inductive switch pipe T1 be set as exporting in photoelectric sensor 11 it is low
It is opened when level signal, therefore inductive switch pipe T1 is in an open state, inductive switch pipe T1 can be by its first end received
One clock signal CK1 is exported as trigger signal Trigger to driving chip 301.Driving chip 301 is received comprising the first touching
The trigger signal for touching location information can control terminal 300 for the first touch location and export the electrostatic field of force, realize tactile again

It should be noted that including photoelectric sensor 11 in induction component 101, tactile sense reproduction picture is the feelings of black and white screen
Under condition, the region area that dark pixel forms in tactile sense reproduction picture is at least more than 0.5cm2.If the area surface of dark pixel composition
Product is too small, then dark pixel will receive the influence of bright pixel around.The light that bright pixel issues can inject the corresponding pixel of dark pixel and drive
Photoelectric sensor 11 in dynamic circuit 100, then photoelectric sensor 11 generates photoelectric current, and second end exports high level signal, makes to feel
Inductive switch pipe T1 closure, can not export trigger signal Trigger to driving chip 301, cannot achieve tactile sense reproduction.
It sets in the region that dark pixel forms at least more than 0.5cm2, in this way, most intermediate in the region of dark pixel composition
Dark pixel not will receive the influence of bright pixel around, when finger touches, blocked the light of extraneous injection, photoelectric sensor
11 defeated low level signals, and then inductive switch pipe T1 can be made to open output trigger signal Trigger to driving chip 301, at this
Tactile sense reproduction is realized at touch location.

As a kind of possible design, referring again to Fig. 3, pixel-driving circuit 100 further includes resistance R, and the one of resistance R
End is connected with the second end of inductive switch pipe T1, and the other end is configured to receive low level signal ref.It is arranged in this way, resistance R
The low level one end that is used to receive be low potential, since resistance R produces pressure difference, so that resistance R and inductive switch pipe T1
The current potential of the connected other end of second end is raised, the current potential raised less than the first clock signal low level signal current potential so that
First clock signal CK1 can be transferred to driving chip 301 as trigger signal Trigger when inductive switch pipe T1 is opened.
