Detailed Description
In order to make the aforementioned and other features and advantages of the invention more comprehensible, embodiments accompanied with figures are described in detail below.
Fig. 1 is a schematic diagram of a display device according to an embodiment of the invention. Referring to fig. 1, the display device 100 includes a foldable display panel 102, a sensor 104, and a driving circuit 106, wherein the driving circuit 106 is electrically connected to the foldable display panel 102 and the sensor 104. The foldable display panel 102 may be configured to display in an unfolded state or a folded state as shown in fig. 2, where the foldable display panel 102 includes a plurality of solid pixels, and in the folded state, only a portion of the solid pixels on the foldable display panel 102 may be used for displaying images. For example, in fig. 2, the foldable display panel 102 folded in half has only the pixels on the display plane FA for displaying images, and the pixels on the display plane FB are not used for displaying images, that is, in the ultra high definition display mode, the number of the pixels on the foldable display panel 102 is smaller than the number of the pixels on the foldable display panel in the normal display mode. In some embodiments, the foldable display panel 102 folded in half can also display images of the solid pixels on the display surfaces FA and FB in the ultra high definition mode, and is not limited to displaying images of only some of the solid pixels. The foldable display panel 102 may be implemented by, for example, a liquid crystal display panel or an organic light emitting display panel, but not limited thereto. The sensor 104 is used for detecting the folding state of the foldable display panel 102, and may be implemented by at least one of a force sensor, a capacitance sensor, a light sensor, a resistance sensor, and a piezoelectric detector, but not limited thereto.
In addition, the driving circuit 106 may be implemented by a chip, which may include a processor, a gate driver, and a source driver, but not limited thereto. The driving circuit 106 may adjust the display mode of the foldable display panel 102 according to the detection result of the sensor 104. For example, when the foldable display panel 102 is in the unfolded state, the driving circuit 106 may drive the foldable display panel 102 to display in the normal display mode according to the first original pixel data received by the driving circuit 106, and when the foldable display panel 102 is in the folded state, the driving circuit 106 may drive the foldable display panel 102 to display in the ultra high definition display mode according to the second original pixel data received by the driving circuit 106, that is, the amount of image data according to which the foldable display panel 102 displays the same image in the normal display mode and the ultra high definition display mode is different. In the normal display mode, a ratio of the resolution of the solid pixels displayed on the foldable display panel 102 to the resolution of the first original pixel data corresponding thereto (i.e., the number of drivable solid pixels preset by the first original pixel data) is a first ratio, and in the ultra-high-definition display mode, a ratio of the resolution of the solid pixels displayed on the foldable display panel 102 (i.e., the number of solid pixels) to the resolution of the second original pixel data corresponding thereto (i.e., the number of drivable solid pixels preset by the second original pixel data) is a second ratio, where the first ratio is greater than the second ratio. For example, the first ratio may be made equal to 1 and the second ratio less than 1.
Thus, when the foldable display panel 102 is in the folded state, the foldable display panel 102 displays according to the second original pixel data having the resolution exceeding the number of the entity pixels performing the display, so that the visual resolution of the foldable display panel 102 in the folded state can be improved, and the display quality of the display device is prevented from being reduced due to the reduction of the number of the entity pixels available for the display. That is to say, the foldable display panel 102 of the embodiment can improve the visual resolution under the condition that the number of the solid pixels capable of displaying is decreased, so as to meet the requirement of a general user for the high visual resolution of the small-sized display screen, and the display quality of the display device 100 in the folded state can also meet the experience and habit of the user when the user watches the small-sized display screen with the high visual resolution, thereby improving the acceptance of the user for the display device 100.
In some embodiments, when the foldable display panel 102 is in the folded state (ultra high definition display mode), the amount of image data equivalently displayed by the same physical Pixel in the foldable display panel 102 may be larger than the amount of image data equivalently displayed in the unfolded state (normal display mode), for example, sub-Pixel Rendering (SPR) technology may be used to improve the visual resolution, so that the physical Pixel equivalently displays more image data. The driving circuit 106 may perform a sub-pixel rendering process on the second original pixel data in the ultra high definition display mode to generate sub-pixel driving data, and drive the corresponding physical sub-pixels according to the sub-pixel driving data. In the normal display mode (i.e., when the foldable display panel 102 is in the unfolded state), the first original pixel data is directly used as the pixel driving data to drive the corresponding physical pixel.
For example, fig. 3 is a schematic diagram of an arrangement of solid pixels of a foldable display panel according to an embodiment of the invention. The foldable display panel 102 includes solid pixels P11 to PV2H, wherein the display surfaces FA and FB respectively include H × V solid pixels, and each solid pixel includes a red sub-pixel R, a green sub-pixel G, and a blue sub-pixel B. The first original pixel data may include, for example, 2H × V pixel data for driving the physical pixels P11-PV 2H, and each pixel data may include red, green and blue sub-pixel data for driving the red sub-pixel R, the green sub-pixel G and the blue sub-pixel B, respectively. When the foldable display panel 102 is in the unfolded state, the driving circuit 106 may drive the physical pixels P11 to PV2H by using the 2H × V pixel data included in the first original pixel data as the pixel driving data, respectively. As described in the above embodiment, in the normal display mode, the resolution of the first original pixel data is 2H × V, so that the ratio of the resolution of the physical pixel displayed on the foldable display panel 102 to the resolution of the corresponding first original pixel data is equal to 1, i.e., the first ratio is equal to 1.
Taking the embodiment of fig. 4A and 4B as an example, when the foldable display panel 102 is in the folded state, the foldable display panel 102 displays only H × V solid pixels on the display surface FA. In the embodiment of fig. 4A and 4B, the second original pixel data may include, for example, 1.5H × V pixel data D11 to DVM, where M is equal to 1.5H. The driving circuit 106 may perform sub-pixel rendering on the second original pixel data to obtain sub-pixel driving data, and then drive the corresponding physical sub-pixels according to the sub-pixel driving data.
Taking the pixel data processing corresponding to the real pixels P11 and P12 in the horizontal direction as an example, the real pixels P11 and P12 perform display using the pixel data D11 to D13. In detail, the sub-pixel driving data of the blue sub-pixel and the red sub-pixel in the physical pixel P11 can be, for example, equal to the blue sub-pixel data D11B and the red sub-pixel data D11R in the pixel data D11, respectively, the sub-pixel driving data of the green sub-pixel in the physical pixel P11 can be, for example, equal to W11 × D11G + W12 × D12G, where D11G and D12G are, respectively, the green sub-pixel data in the pixel data D11 and the green sub-pixel data in the pixel data D12, and W11 and W12 are, respectively, weights occupied by the green sub-pixel data D11G and the green sub-pixel data D12G in the sub-pixel driving data of the green sub-pixel. Similarly, the sub-pixel driving data of the blue sub-pixel and the red sub-pixel in the physical pixel P12 may be equal to W12 × D12B + W13 × D13B and W12'× D12R + W13' × D13R, respectively, where D12B and D13B are the blue sub-pixel data in the pixel data D12 and D13, D12R and D13R are the red sub-pixel data in the pixel data D12 and D13, W12 and W13 are the weights of the blue sub-pixel data D12B and the blue sub-pixel data D13B in the sub-pixel driving data of the blue sub-pixel, and W12 'and W13' are the weights of the red sub-pixel data D12R and the red sub-pixel data D13R in the sub-pixel driving data of the red sub-pixel, respectively. In addition, the sub-pixel driving data of the green sub-pixel in the real pixel P12 may be equal to the green sub-pixel data D13G in the pixel data D13, for example. In addition, the sub-pixel driving data of the remaining physical pixels P14-P1H can also be obtained in a similar manner, and are not described herein again. By driving the physical pixels P11 to P1H using the sub-pixel drive data obtained by performing the sub-pixel rendering process on the second original pixel data, the physical pixels P11 to P1H can visually display the effect of 1.5H pieces of pixel data (pixel data D11 to D1M), and the visual resolution can be improved by 1.5 times. As described in the foregoing embodiment, in the ultra high definition display mode, the resolution of the first original pixel data is 1.5H × V, so that the ratio of the resolution of the physical pixel displayed on the foldable display panel 102 to the resolution of the corresponding second original pixel data is equal to 2/3, that is, the second ratio is equal to 2/3, and the first ratio (1) is greater than the second ratio (2/3).
By analogy, the pixel data of other columns in the horizontal direction may also be subjected to the sub-pixel rendering process in a similar manner to obtain corresponding sub-pixel drive data. In addition, the pixel data in the vertical direction may also be subjected to sub-pixel rendering processing in a similar manner to obtain corresponding sub-pixel drive data. As described in the above embodiment, in the normal display mode, the ratio of the resolution of the entity pixels displayed on the foldable display panel 102 to the resolution of the first original pixel data corresponding thereto is only equal to 1, while in the ultra-high definition display mode, although the number of the entity pixels used for displaying is reduced, after the visual resolution is improved by the sub-pixel rendering technique, the ratio of the resolution of the entity pixels displayed on the foldable display panel 102 to the resolution of the second original pixel data corresponding thereto is equal to 2/3. That is, the visual resolution of the display screen is increased by 1.5 times with a reduction in the number of solid pixels to display, and the resolution perceived by the viewer is increased. By analogy, the visual resolution of the whole display picture can be improved by 2.25 times by simultaneously improving the visual resolution in the horizontal direction and the vertical direction.
In some embodiments, the weights of the red, green, and blue sub-pixel driving data in the pixel driving data may be adjusted according to different arrangement manners of the physical pixels on the foldable display panel 102, so as to obtain the adjusted pixel driving data to drive the physical pixels. For example, the arrangement of the solid pixels shown in fig. 5 is different from the arrangement of the solid pixels shown in fig. 3, and when the embodiment of the foregoing embodiment is applied to the embodiment of fig. 5, the weights of the red, green and blue sub-pixel driving data in the pixel driving data may need to be adjusted to achieve the best display effect. The foldable display panel 102 is folded in half in the above embodiments, but the folding manner of the foldable display panel 102 is not limited thereto, and the foldable display panel 102 may be folded in more than one manner in other embodiments.
In addition, as shown in fig. 6A and 6B, the gate driver 602 in the driving circuit 106 may be disposed at a side of the foldable display panel 102 intersecting with the folding line of the foldable display panel (as shown in fig. 6A) or at a side parallel to the folding line (as shown in fig. 6B), for example. In the embodiment of fig. 6A, all the gate drivers 602 need to be activated in the unfolded state, and only a part of the gate drivers 602 need to be activated in the folded state, for example, the foldable display panel 102 after being folded into two has two opposite display surfaces, only the gate driver 602 corresponding to the display surface responsible for displaying is activated, and the gate driver 602 corresponding to the other display surface responsible for displaying is not activated. That is, the driving signal or the actuation condition of the gate driver 602 in the extended state is different from that in the folded state. In addition, the driving quantity of the gate lines can be reduced in the folded state. In the embodiment of fig. 6A, two gate drivers 602 are illustrated, but the invention is not limited thereto, and there may be different numbers of gate driver 602 groups according to the folding design or other requirements. In the embodiment of fig. 6B, since the gate driver 602 is disposed at the side parallel to the folding line, the driving signals or actions of the gate driver 602 in the unfolded state and the folded state are the same.
Fig. 7 is a flowchart of a display method of a display device according to an embodiment of the invention. In the above embodiments, the display method of the display device may include at least the following steps. First, whether the foldable display panel is in a folded state is determined (step S702), and if the foldable display panel is not in the folded state but in an unfolded state, the foldable display panel is driven to display in a normal display mode (step S704), for example, the first original pixel data may be used as the pixel driving data to drive the corresponding entity pixels in the foldable display panel. Conversely, if the foldable display panel is in the folded state, the foldable display panel is driven to display in the ultra high definition display mode (step S706), for example, the foldable display panel may be driven according to the second original pixel data. In the ultra high definition display mode, the number of the entity pixels displayed on the foldable display panel can be smaller than the number of the entity pixels displayed in the normal display mode, in addition, the ratio of the resolution of the entity pixels displayed on the foldable display panel in the normal display mode to the resolution of the first original pixel data corresponding to the entity pixels is a first ratio, the ratio of the resolution of the entity pixels displayed on the foldable display panel in the ultra high definition display mode to the resolution of the second original pixel data corresponding to the entity pixels is a second ratio, and the first ratio is larger than the second ratio.
In some embodiments, the amount of image data that is equivalently displayed in the ultra high definition display mode by the same physical pixel in the foldable display panel may be greater than the amount of image data that is equivalently displayed in the normal display mode. For example, the second original pixel data may be subjected to a sub-pixel rendering process to generate sub-pixel driving data, and the corresponding physical sub-pixels are driven according to the sub-pixel driving data.
Fig. 8 is a schematic diagram of a foldable display panel according to an embodiment of the invention. As shown in fig. 8, the folding direction of the foldable display panel 102 is not limited to the horizontal folding direction of the above embodiment, but may be a vertical folding direction as in the present embodiment. In addition, the number of folding times is not limited to 2 folds, and for example, the present embodiment may be a 3-fold or more folding manner.
In summary, the driving circuit of the present invention can respectively drive the foldable display panel to display in the ultra high definition display mode and the normal display mode when the foldable display panel is in the folded state and the unfolded state. The ratio of the resolution of the entity pixels displayed on the foldable display panel in the normal display mode to the resolution of the first original pixel data corresponding to the entity pixels is a first ratio, the ratio of the resolution of the entity pixels displayed on the foldable display panel in the ultra-high definition display mode to the resolution of the second original pixel data corresponding to the entity pixels is a second ratio, and the first ratio is larger than the second ratio. In addition, in some embodiments, the amount of image data that is equivalently displayed by the same physical pixel in the foldable display panel in the ultra high definition display mode may be greater than the amount of image data that is equivalently displayed in the normal display mode. Therefore, the visual resolution of the foldable display panel in the folded state can be improved, and the display quality of the display device is prevented from being reduced due to the reduction of the number of the solid pixels available for display. That is to say, the foldable display panel can improve the visual resolution under the condition that the number of the solid pixels capable of being used for displaying is reduced, so as to meet the requirement of a general user on the high visual resolution of the small-size display screen, and the display quality of the display device in a folded state can also meet the experience and habit of the user in the past when the user watches the small-size screen with the high visual resolution, thereby improving the acceptance of the user on the display device.
Although the present invention has been described with reference to the above embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
