Eye pattern picture.While left-eye image luminous signal transmitting element sends left-eye image luminous signal to oled panel, touch-control list
The touch-control sending module of unit to the contact panel sends scanning drive signal.When user has touch control operation, at touch point
Capacitance parameter can change, touch-control receiver module from contact panel receive panel touch capacitance parameter change, and according to
The change calculations of the capacitance parameter obtain the coordinate of touch point, then touch point coordinate information are conveyed to into corresponding mobile phone application
Program.
Then, the right eye scanning signal transmitting element in 3D control modules sends first right eye scanning signal to OLED faces
Plate.Right eye scanning signal is sequentially providing to the scanner driver of oled panel each scan line of oled panel, and oled panel is each
Pixel is temporarily stored in right eye scanning signal in image element circuit.Then send single by the eye image luminous signal in 3D control modules
Unit to oled panel sends eye image luminous signal, the transmitting drive division of oled panel by the eye image luminous signal successively
It is supplied to each light emitting control line of oled panel, oled panel to light so as to show eye image.Perform lower display again afterwards
Left-eye image, the circulation for showing eye image.
In other embodiments, touch-control sending module sends scanning drive signal and touch-control receiver module receiving panel is touched
The step of touching capacitance parameter and change, it is also possible to which the eye image luminous signal transmitting element in 3D control modules sends right eye figure
As carrying out while luminous signal.Certainly, the step can also send left-eye image in left-eye image luminous signal transmitting element
All carry out while luminous signal and while eye image luminous signal transmitting element sends eye image luminous signal.And
For other 3D touch control devices such as panel computer, can realize improving touching signals signal to noise ratio by identical scheme.
Embodiment described above is only the preferred embodiment lifted to absolutely prove the present invention, the protection model of the present invention
Enclose not limited to this.Equivalent substitute or conversion that those skilled in the art are made on the basis of the present invention, in the present invention
Protection domain within.Protection scope of the present invention is defined by claims.
