When the display device display two-dimensional picture, the two-dimensional picture display control mode allows the bias frequency to be half of the bias frequency when the display device displays the three-dimensional picture, thereby effectively reducing the power consumption when the display device switches to display the two-dimensional picture. When the display device display two-dimensional picture, the two-dimensional picture display control mode also allows the overall resolution of the row direction or column direction to be half of the overall resolution of the display device when displaying the three-dimensional picture. Because the PPI of the display device displaying the three-dimensional picture is half of the actual PPI of the display device, the resolution of the display device displaying the three-dimensional picture and the resolution when displaying the two-dimensional picture are relatively close, so as to solve the problem of inconsistent resolution between the switch from displaying a three-dimensional picture to a two-dimensional picture.

At this time, the data line Data1 is connected to the source signal output terminal S1, and the data line Data2 is connected to the source signal output terminal S2, . . . , and the data line Data12 is connected to the source signal output S12. That is, at this time, the odd column source signal output terminals (S1, S2, S3) in the odd column source signal output terminal group provide the source signal to the sub-pixels (P101, P102, P103) in the odd column pixel units. Similarly, the even column source signal output terminals (S4, S5, S6) in the even column source signal output terminal group provide the source signal to the sub-pixels (P104, P105, P106) in the even column pixel units.

That is, in this embodiment, the target source signal end group is an odd column source signal output terminal group consisting of the source signal output terminal S1, the source signal output S2, and the source signal output S3. Please note, in this embodiment, the target source signal end group may also be an even column source signal output terminal group. The above example is not a limitation of the present disclosure.
Taking the display device shown in
At this moment, the odd column source signal output terminal S1 in the odd column signal output terminal group provides the source signal to the sub-pixel P101 in the odd column pixel unit and the sub-pixel P104 in the even column pixel unit; the odd column source signal output terminal S2 in the odd column signal output terminal group provides the source signal to the sub-pixel P102 in the odd column pixel unit and the sub-pixel P105 in the even column pixel unit; and the odd column source signal output terminal S3 in the odd column signal output terminal group provides the source signal to the sub-pixel P103 in the odd column pixel unit and the sub-pixel P106 in the even column pixel unit.

At this moment, the odd column source signal output terminals (S1, S2, S3) in the odd column signal output terminal group are simultaneously disconnected and cannot provide the source signal to the sub-pixels (P101, P102, P103) in the odd column pixel unit and the sub-pixels (P104, P105, P106) in the even column pixel unit.
In this embodiment, the first switch and the second switch could be implemented with any one of or a combination of a thin-film transistor, a T-channel metal oxide semiconductor field effect transistor (MOSFET), a P-channel MOSFET, and a complementary MOSFET.
When the display device displays a three-dimensional picture, the scan line is turned on line by line, and each scan line is turned on for a set time period T. During the turning-on period, the switching module controls a source signal output terminal to be electrically connected to a data line. Here, T is a positive integer.
When the display device displays a three-dimensional picture, the grating is turned on. When the human uses his naked eye to view the three-dimensional picture, the PPI of the three-dimensional picture is about half of the actual PPI of the display device. At this time, the first driving timing is used to drive the display device. The first drive timing can be as shown in
At this time, the logic power consumption when the display device displays the three-dimensional picture is: Power=n*Cdata*Vswing*f1/2, where Power is the logic power consumption, n is the number of data lines, Cdata is the parasitic capacitance between the data lines, Vswing is the rotation voltage, f1 is the bias frequency when the three-dimensional picture is displayed, f1=1/T, T=Hus.
When the display device displays a two-dimensional picture, the scan lines are two lines by two lines, and each line is turned on for a period of time 2T. During the turning-on period, the switching module controls a source signal output terminal to be electrically connected to two target data lines at the same time. The two target data lines are two data lines connected to two columns of sub-pixels with the same luminous color.
In this embodiment, the sentence “the scan lines are two lines by two lines” may represent: in the first timing of the display device, the first line scan line and the second line scan line are turned on for the set time period 2T at the same time and the other scan lines are turned off; in the second timing of the display device, the first line scan line and the second line scan line are turned off, the third line scan line and the 4th line scan line are turned on at the same time for the set time period 2T, and so on. Please note, this is only an example, not a limitation of the present disclosure. This arrangement can also be adjusted according to the actual implementation.
Specifically, when the display device displays a two-dimensional picture, the grating is turned off. When the human uses his naked eye to view the two-dimensional picture, the resolution of the two-dimensional picture is equal to the actual resolution of the display device. At this time, the second driving timing is used to drive the display device. The second driving timing can be as shown in
For example, as shown in
At the same time, the logic power consumption when the display device displays a two-dimensional picture is: Power=n*Cdata*Vswing*f2/(2*2), where Power is the logic power consumption, n is the number of data lines, Cdata is the parasitic capacitance between the data lines, Vswing is the deflection voltage and f2 is the bias frequency when a two-dimensional picture is displayed.
Therefore, the resolution of rows/columns of the display device in the second driving timing becomes half of the resolution of the display device in the first driving timing. However, because the PPI of the three-dimensional picture is about half of the actual PPI of the display device, the resolution of displaying the two-dimensional picture is similar to the resolution of displaying the three-dimensional picture. When the display device displays a two-dimensional non-solid color picture, the bias frequency of the display device is f2=1/T. Here, T=2Hus, so f2=(½)f1. That is, the bias frequency when the display device is in the second driving timing is changed to half of that when the display device is in the first driving timing.
In some embodiments of the present disclosure, the display device comprises a naked-eye three-dimensional display device.
Since the resolution of the naked-eye three-dimensional display device is generally high, the data selector (multiplexer, MUX) cannot be used. That is, the display device in this embodiment can be adapted to the display device without a data selector.
In summary, the present disclosure adopts the above structure of the display device to implement the switch between the three-dimensional picture and the two-dimensional picture. When the display device switches to display a two-dimensional picture, it can maintain a resolution similar to that when a three-dimensional picture is disclosed. This improves the discomfort of human eyes. When the display device switches to display a two-dimensional picture, the logic power consumption is reduced. The present disclosure could be applied to the switch between the two-dimensional picture and three-dimensional picture, which is originally based on slit interference naked-eye three-dimensional display. In addition, the present disclosure could be also applied to a display device with no data selector. The applicability of the present disclosure is extensive.
The technical solution proposed in the present disclosure could be implemented in a specific product. In this way, the display panel resolution of 8K/4K switching could be achieved with no need to include a chip that supports a conventional resolution switching. In the implemented product chip, the supported polarity of a source chip is shown in

At step 102, when the display device displays a two-dimensional picture, the scan lines two are turned on lines by two lines. Each scan line is turned on for a set time period 2T.

The target data lines are two data lines connected to two columns of sub-pixels with the same luminous color.
