The present invention relates to a display technology, and more particularly to a display device and method.

With the advancement of display technology, displays that support three-dimensional (3D) video playback have become popular. The difference between 3D display and two-dimensional (2D) display is that 3D images allow viewers to feel the stereoscopic effect in the image, such as the three-dimensional facial features and depth of field, etc., while the traditional 2D The image does not show this effect. In general, the principle of 3D display technology is to set a special screen mask on the screen of the display, or let the viewer wear 3D glasses, and display the left eye image for the viewer's left eye on the screen of the display and let The right eye image of the viewer's right eye is viewed so that the viewer's left and right eyes can respectively see the corresponding left and right eye images at different time points, and the visual residual characteristics are used to make the viewer feel the 3D vision. effect.

On the other hand, from the perspective of the display, the existing 3D display technology can be mainly divided into two display modes: time division multiplexing and space multiplexing. Time-division multiplex is to let the display display different above-mentioned left and right eye images on the full screen at different time points. For example, the left side of the display screen displays the right eye image, and the right half of the display screen displays the left eye image.

However, if the image processing speed of the display and/or the panel driving speed is insufficient, the viewer's comfort in viewing the 3D image may be reduced. In addition, when the display is to spatially render 3D images, the conventional method may also cause problems such as burrs or blurred images at the intersection of the left and right eye images.

In view of the above, the present invention provides a display device and method, which can effectively speed up the image processing speed of the display device, thereby improving the comfort of the viewer when viewing the 3D image.

The invention provides a display device, which comprises a display panel, a plurality of driving modules and a control module. The display panel includes a plurality of independent display areas that are not electrically connected to each other. The drive modules are coupled to the separate display areas. The control module is coupled to the drive modules, wherein the control module selectively enables the drive modules according to the display mode of the display panel, and the corresponding drive display module drives the corresponding independent display area.

The present invention further provides a display method. The display method is applicable to a display device. The display device includes a display panel. The display method includes: dividing the display panel into a plurality of independent display regions that are not electrically connected to each other; Driving the modules, and respectively coupling the driving modules to the independent display areas; selectively enabling or disabling the driving modules according to the display mode of the display panel; The movable module drives the corresponding independent display area.

Based on the above, by driving a separate display area through a driving module (or circuit), the present invention can utilize multiple driving modules (or circuits) to drive multiple independent display areas on the same display panel, greatly surpassing the conventional A single driving circuit drives the image driving mode of the entire display panel, thereby effectively improving the user's comfort when viewing 3D images, and reducing the occurrence of burrs or blurred images at the intersection of the left and right eye images.

In order to improve the smoothness of the display device when playing 3D images, the present invention provides a display method for dividing the display panel of the display device into non-electrical connections A plurality of independent display areas are connected, and each of the independent display areas is driven by a dedicated drive module. Therefore, when the 3D video image is played, the display device proposed by the present invention can effectively improve the problem that the 3D video image cannot be played smoothly due to insufficient screen processing speed of the display.

Further, the present invention further discloses a display device which can be used to embody the above display method. In order to make the content of the present invention easier to understand, the following specific embodiments are illustrative of the embodiments of the present invention.

FIG. 1 is a schematic diagram of a display device according to an embodiment of the invention. Referring to FIG. 1 , the display device 10 can be any type of display such as a liquid crystal display (LCD), a plasma display panel (PDP), or a LED display.

The display device 10 includes a display panel 11, drive modules 12_1~12_4, and a control module 13. The display panel 11 includes independent display areas 11_1 to 11_4, and the independent display areas 11_1 to 11_4 are not electrically connected to each other. For example, the independent display area 11_1 has a plurality of first data lines and a plurality of first scan lines, and the independent display area 11_2 has a plurality of second data lines and a plurality of second scan lines, and the independent display area 11_3 has a plurality of The three data lines and the plurality of third scan lines, and the independent display area 11_4 has a plurality of fourth data lines and a plurality of fourth scan lines. The non-electrical connection mentioned here means that the data lines belonging to different independent display areas 11_1 11 11_4 are not electrically connected to each other, and the scan lines belonging to different independent display areas 11_1 11 11_4 are mutually connected. They are not electrically connected to each other.

If the display panel 11 is defined to have a side 112, a side 114, and a side 116 And the side edge 118, wherein the side edge 112 is opposite to the side edge 114, and the side edge 116 is opposite to the side edge 118, then the independent display area 11_1 and the independent display area 11_2 are adjacent to the side edge 112, and the independent display area 11_3 is adjacent to the independent display area 11_4. The side 114, the independent display area 11_1 and the independent display area 11_3 are adjacent to the side 116, and the independent display area 11_2 and the independent display area 11_4 are adjacent to the side 118. Further, with respect to the total display area of the display panel 11, the sizes of the individual display areas 11_1 to 11_4 are respectively one quarter of the total display area of the display panel 11.

The driving modules 12_1~12_4 are respectively coupled to the independent display areas 11_1~11_4 to drive the independent display areas 11_1~11_4 to display images. For example, the driving module 12_1 can provide the data driving signal DD1 to the first data line in the independent display area 11_1, and provide the scanning signal SS1 to the first scanning line in the independent display area 11_1, thereby driving the independent display area 11_1 to display a first An image. The driving module 12_2 can provide the data driving signal DD2 to the second data line in the independent display area 11_2, and provide the scanning signal SS2 to the second scanning line in the independent display area 11_2, thereby driving the independent display area 11_2 to display a second image. . The driving module 12_3 can provide the data driving signal DD3 to the third data line in the independent display area 11_3, and provide the scanning signal SS3 to the third scanning line in the independent display area 11_3, thereby driving the independent display area 11_3 to display a third image. . The driving module 12_4 can provide the data driving signal DD4 to the fourth data line in the independent display area 11_4, and provide the scanning signal SS4 to the fourth scanning line in the independent display area 11_4, thereby driving the independent display area 11_4 to display a fourth image. .

The control module 13 is coupled to the drive modules 12_1~12_4. The control module 13 can The drive modules 12_1~12_4 are selectively enabled or disabled according to the display mode of the display panel 11. The enabled drive module can drive its corresponding independent display area. Conversely, the disabled drive module is in standby or idle state. For example, if the control module 13 enables the driving module 12_1 and disables the driving modules 12_2~12_4, the enabled driving module 12_1 can drive the independent display area 11_1, and the disabled driving module 12_2~ 12_4 does not work. In particular, in this case, since the independent display areas 11_1~11_4 are not electrically connected to each other, only the independent display area 11_1 coupled to the driving module 12_1 displays the first image, and the independent display areas 11_2~11_4 are not displayed. Any image.

In detail, the control module 13 can include a controller 132 and a decoder 134. The controller 132 can generate the control signal CS according to the display mode of the display panel 11. The decoder 134 is coupled to the controller 132 and the driving modules 12_1~12_4. The decoder 134 can receive the control signal CS and generate the enable signals EN1~EN4 according to the control signal CS. The driving modules 12_1~12_4 can respectively receive the enable signals EN1~EN4 to determine whether to drive the independent display areas 11_1~11_4 according to the enable signals EN1~EN4.

For example, the driving module 12_1 may include a processor 122_1 and a driving circuit 124_1. The processor 122_1 is, for example, a controller of the drive circuit 124_1 and can receive the enable signal EN1. When the enable signal EN1 can enable the processor 122_1, for example, the enable signal EN1 is "high", or the enable signal EN1 has an image signal corresponding to the independent display area 11_1, the processor 122_1 can The control driving circuit 124_1 generates the data driving signal DD1 and the scanning signal SS1 to drive the independent display area. Domain 11_1 (ie, drive circuit 124_1 is in an enabled state). In addition, the driving module 12_2 may include a processor 122_2 and a driving circuit 124_2. The driving module 12_3 may include a processor 122_3 and a driving circuit 124_3. The driving module 12_4 may include a processor 122_4 and a driving circuit 124_4, and the driving module 12_2~ The operation mode of the 12_4 is basically the same as or similar to that of the driving module 12_1, so the detailed description is not repeated here.

In the present embodiment, since the independent display areas 11_1~11_4 are independently driven by the drive modules 12_1~12_4, the drive states of the display panel 11 actually include the drive states 1~16 listed in Table 1 below. Among them, "1" indicates that the image is driven and/or displayed, and "0" indicates that the image is not driven and/or no image is displayed.

For example, when the display panel 11 is in the driving state 1, since the independent display regions 11_1 to 11_4 are not driven, the independent display regions 11_1 to 11_4, for example, present a black screen. When the display panel 11 is in the driving state 16, since the independent display areas 11_1~11_4 are all driven, the independent display areas 11_1~11_4 can be used to display images, and the remaining driving states 2~15 and so on.

It is worth mentioning that although the independent display areas 11_1~11_4 are driven by the drive modules 12_1~12_4 respectively, the same time point (different independent display areas may have some time error) is presented in the independent display area 11_1. The image on the ~11_4 may be an image corresponding to different display positions of the same image signal or frame on the display panel 11, and the image signal or frame may be a general 2D image signal or a 3D image signal. The invention is not limited thereto. For example, when the controller 132 receives the image signal of a 3D image, the controller 132 can entrain the image signal in the control signal CS or otherwise transmit to the decoder 134. Then, the decoder 134 can decode the control signal CS and/or the image signal to display on the display panel 11 according to the independent display area corresponding to the enabled driving module. The position divides the image signal into a plurality of image signal segments, and transmits the image signal segments to the enabled driving module respectively, thereby displaying the image through a combination of the driven independent display regions.

For example, in the embodiment, the display mode of the display panel 11 may include a two-dimensional (2D) display mode, a side-by-side three-dimensional (3D) display mode, and a top and bottom ( Top-bottom) 3D display mode. The 2D display mode is, for example, a normal display mode that does not involve three-dimensional video playback. For example, when the display panel 11 is in the 2D display mode, the control module 13 can simultaneously enable the driving modules 12_1~12_4, and transmit the image signals to the driving modules 12_1~12_4 in the form of the image signal segments respectively. At the same time, the complete image is displayed on the independent display areas 11_1~11_4.

When the display panel 11 starts playing a 3D image, the display panel 11 can selectively operate in a side-by-side 3D display mode or a top-bottom 3D display mode. Wherein, when the display panel 11 is operated in the side-by-side 3D display mode, the display panel 11 can quickly switch between displaying the left image and the right image on the left and right sides thereof. When the display panel 11 is operated in the top and bottom 3D display mode, the display panel 11 can quickly switch between displaying the top image and the bottom image on the upper and lower sides thereof. However, whether it is a side-by-side 3D display mode or a top-bottom 3D display mode, the viewer can feel the 3D visual effect by the characteristics of visual residual.

For example, FIG. 2 is a schematic diagram of a side-by-side 3D display mode according to an embodiment of the invention. Referring to FIG. 1 and FIG. 2 simultaneously, since the side-by-side 3D display mode is to quickly switch between displaying the left image and the right image on the left and right sides of the display panel 11, for example, in the time periods T1 and T3, the control module 13 Can drive The movable module 12_1 and the driving module 12_3 are configured to display a left image (for example, a right eye image) in the independent display area 11_1 and the independent display area 11_3. For example, in the time periods T2 and T4, the control module 13 can enable the driving module 12_2 and the driving module 12_4 to display a right image (for example, a left eye image) in the independent display area 11_2 and the independent display area 11_4. In addition, during the time periods T1 and T3, the control module 13 can disable the driving module 12_2 and the driving module 12_4, so that the independent display area 11_2 and the independent display area 11_4 do not display images. In the time period T2 and T4, the control module 13 can disable the driving module 12_1 and the driving module 12_3, so that the independent display area 11_1 and the independent display area 11_3 do not display images.

For another example, FIG. 3 is a schematic diagram of a top and bottom 3D display mode according to an embodiment of the invention. Referring to FIG. 1 and FIG. 3 simultaneously, since the top and bottom 3D display mode is to quickly switch between displaying the top image and the bottom image on the top and bottom half of the display panel 11, for example, in the time periods T1 and T3, the control module 13 The driving module 12_1 and the driving module 12_2 can be enabled to display a top image (for example, a right eye image) in the independent display area 11_1 and the independent display area 11_2. For example, in the time periods T2 and T4, the control module 13 can enable the driving module 12_3 and the driving module 12_4 to display a bottom image (for example, a left eye image) in the independent display area 11_3 and the independent display area 11_4. In addition, during the time periods T1 and T3, the control module 13 can disable the driving module 12_3 and the driving module 12_4, so that the independent display area 11_3 and the independent display area 11_4 do not display images. In the time period T2 and T4, the control module 13 can disable the driving module 12_1 and the driving module 12_2, so that the independent display area 11_1 and the independent display area 11_2 do not display images. It is worth mentioning that the time period T1~T4 For example, it is 120~240 microseconds, etc., and the practical requirements are adaptively adjusted, and the time periods T1~T4 are only for illustrative purposes.

Thereby, through the special screen mask or the viewer wearing the 3D glasses, the present invention can utilize the characteristics of the visual residual to allow the viewer to feel the 3D visual effect when viewing the image presented by the display device 10, and because of the left, The right image is independently driven and displayed by different driving modules. Therefore, in the overall image processing performance and image fluency, the present invention can greatly surpass the conventional image driving method of driving the entire display panel with a single driving circuit. Thereby effectively improving the user's comfort when viewing 3D images.

In another aspect, the present invention also provides a display method suitable for use in a display device (e.g., display device 10 of FIG. 1).

For example, FIG. 4 is a flowchart of a display method according to an embodiment of the invention. Referring to FIG. 4, in step S410, a display panel may be divided into a plurality of independent display areas that are not electrically connected to each other. Next, in step S420, a plurality of driving modules are provided, and the driving modules are respectively coupled to the independent display regions. In step S430, the driving modules are selectively enabled or disabled according to the display mode of the display panel. Then in step S440, the corresponding independent display area is driven by the enabled drive module.

The implementation details of the above display method can be obtained from the above embodiments in detail, and the detailed description is not repeated here.

In summary, the display device and method of the present invention utilizes a plurality of drive modules to drive different independent display areas on a display panel in a one-to-one manner. In 3D In terms of the playback quality of the image, the present invention can greatly exceed the conventional panel driving method of driving the entire display panel with a single driving circuit, thereby effectively improving the user's comfort when viewing 3D images. In addition, the present invention can also support a general 2D playback mode, thereby improving the smoothness of the display device when playing general images and/or high definition (HD) images.
