Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application is based on and claims the benefit of priority from Korean Patent Application No. 10-2020-0052860 filed in the Korean Intellectual Property Office on April 29, 2020, the disclosure of which is incorporated herein by reference in its entirety. Technical Field

[0003] The present disclosure relates to a display device and a control method thereof, for example, to a display device that performs image processing on content and displays the image-processed content and a control method thereof. Background Art

[0004] With the development of image devices, high-quality content is being produced. In particular, recently, content with a frame rate of 120 Hz or higher is produced.

[0005] When playing back such content, if the operating frequency of the display device is 120 Hz or higher, the frame rate of the content can be displayed as it is, but most conventional display devices have an operating frequency of 60 Hz or lower.

[0006] For example, Figure 1 As shown, a display device operating at 60 Hz can display content while omitting some frames of the content to play back 120 Hz content. In this case, there may be a problem that the content cannot be played smoothly.

[0007] Upgrading the hardware specifications of the display device may be a method of solving the above problem. However, in order to enable the display device to play back content at a frame rate of 120 Hz or higher, there may be a problem of increased manufacturing costs.

[0008] For example, when displaying one frame of content with a frame rate of 120Hz, the entire display area must be scanned for 1 / 120 seconds. In addition, as the resolution of the display device increases, the time for displaying one pixel line becomes shorter. For example, in the case of a display device with an 8K resolution, the horizontal and vertical lengths of the pixel are 7680×4320, and because scanning is performed in the vertical direction, one pixel line can be scanned for 1 / (120×4320)s in the above example.

[0009] If 60Hz content is displayed in a display device with 4K resolution, one pixel line may be scanned for 1 / (60×2160)s. That is, it may be necessary to significantly shorten the scanning time of one pixel line to play back high-quality content, in which case there may be a problem of excessive increase in the manufacturing cost of the display device.

[0010] Therefore, there is a need to develop a method for improving the response characteristics of contents while reducing the manufacturing cost of the display device. Summary of the invention

[0011] Embodiments of the present disclosure provide a display device and a control method thereof for improving response characteristics while maintaining an inherent resolution of the display device.

[0012] According to an example embodiment, a display device includes: a display panel configured to drive frames of a first resolution at a first frame rate; a communication interface including a circuit configured to receive content; and a processor configured to adjust the received content to a second resolution based on that the frame rate of the received content is greater than the first frame rate, and control the display panel to display the content of the second resolution at a second frame rate, the second frame rate being greater than the first frame rate.

[0013] The display panel may include a plurality of gate lines and a plurality of data lines, and may be configured to simultaneously drive two adjacent gate lines of the plurality of gate lines, wherein each of the plurality of data lines is configured to provide data to pixels of the same column.

[0014] The processor may be configured to repeatedly display a pixel line of the content at the second resolution through two adjacent gate lines among the plurality of gate lines.

[0015] The display panel may display one frame within a first time corresponding to a first frame rate, and wherein the processor may be configured to control the display panel to display one frame of content of a second resolution within a second time, the second time being less than the first time and corresponding to a second frame rate.

[0016] The processor may be configured to scale the received content to a second resolution based on an equivalent value of a vertical resolution of the display panel.

[0017] The processor may be configured to adjust a horizontal resolution of the content based on a horizontal resolution of the display panel and to adjust a vertical resolution of the content based on an equal value of a vertical resolution of the display panel.

[0018] The processor may be configured to identify an equivalent value of a vertical resolution of the display panel based on the frame rate of the content and the first frame rate.

[0019] The first frame rate may be a maximum frame rate that the display panel can output, and wherein the vertical resolution of the display panel is the number of pixels arranged in a vertical direction among a plurality of pixels of the display panel.

[0020] The processor may be configured to adjust the content to a second resolution based on the content being of the first type, and to control the display panel to display the content at a first frame rate without adjusting a resolution of the content based on the content being of the second type.

[0021] The processor may be configured to increase the frame rate of the content by performing frame interpolation on the content based on the frame rate of the content being the same as the first frame rate, and to adjust the content with the increased frame rate to the second resolution.

[0022] The processor is configured to adjust the received content to a second resolution based on a user command to increase the frame rate being input.

[0023] According to an example embodiment, a method for controlling a display device includes: receiving content; adjusting the received content to a second resolution based on a frame rate of the received content being greater than a first frame rate of a display panel; and displaying the content of the second resolution at the second frame rate, the second frame rate being greater than the first frame rate, wherein the display panel is configured to drive frames of the first resolution at the first frame rate.

[0024] The display panel may include a plurality of gate lines and a plurality of data lines, wherein each of the plurality of data lines provides data to pixels of the same column, and wherein displaying may include driving two adjacent gate lines of the plurality of gate lines simultaneously.

[0025] The displaying may include repeatedly displaying a pixel line of the content of the second resolution through two adjacent gate lines among the plurality of gate lines.

[0026] The display panel may display one frame within a first time corresponding to a first frame rate, and wherein displaying may include displaying one frame of content of a second resolution within a second time, the second time being less than the first time and corresponding to the second frame rate.

[0027] The adjusting may include adjusting the received content to a second resolution based on an equivalent value of a vertical resolution of the display panel.

[0028] The adjusting may include adjusting a horizontal resolution of the content based on a horizontal resolution of the display panel, and adjusting a vertical resolution of the content based on an equal value of a vertical resolution of the display panel.

[0029] The method may further include identifying an equivalent value of a vertical resolution of the display panel based on the frame rate of the content and the first frame rate.

[0030] The first frame rate may be a maximum frame rate that the display panel can output, and wherein the vertical resolution of the display panel is the number of pixels arranged in a vertical direction among a plurality of pixels of the display panel.

[0031] The adjusting and displaying may include adjusting the content to a second resolution and displaying it at a second frame rate based on the content being the first type, and displaying the content at the first frame rate without adjusting the resolution of the content based on the content being the second type.

[0032] According to various example embodiments, a display device may improve response characteristics by adjusting a resolution of a frame to reduce a time to display the frame.

[0033] Furthermore, since the display device can operate at a relatively low operating frequency compared to the frame rate of the content, the display device can be implemented at a low cost.

[0034] By producing content at a high resolution, although the vertical resolution of the content is reduced by half, the image quality perceived by the user does not deteriorate significantly, and by improving the response characteristics, a smoother image can be output.

[0062] In the present disclosure, the term "user" may refer to a person using a display device or a device (eg, an artificial intelligence electronic device) using the display device.

[0063] Example embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings.

[0064] Figure 2A is a block diagram illustrating an example configuration of a display device 100 according to an embodiment of the present disclosure.

[0065] As a device for displaying content, the display device 100 can be, for example, but not limited to, a television (TV), a desktop personal computer (PC), a notebook, a video wall, a large format display (LFD), a digital signage, a digital information display (DID), a projector display, a digital video disc (DVD) player, a refrigerator, a smart phone, a tablet PC, a monitor, smart glasses, a smart watch, etc., and can be any device as long as the device can display content.

[0066] Reference Figure 2A , the display device 100 may include a display panel 110, a processor (eg, including a processing circuit) 120, and a communication interface (eg, including a communication circuit) 130. However, the embodiment is not limited thereto, and the display device 100 may be implemented in a form that does not include some configurations and further includes other configurations.

[0067] The display panel 110 may include a plurality of pixels and may display an image signal. For example, if implemented with an 8K resolution, the display panel 110 may include a plurality of pixels 7680×4320. If implemented with a 4K resolution, the display panel may include a plurality of pixels 3840×2160. However, the embodiment is not limited thereto, and the display panel may be implemented with various resolutions.

[0068] Each of the plurality of pixels included in the display panel 110 may be composed of sub-pixels, which present, for example but not limited to, red (R), green (G), and blue (B). In another example, in addition to RGB, the pixel may also include a sub-pixel presenting white (W). However, the embodiment is not limited thereto, and each of the plurality of pixels may be implemented in various forms.

[0069] The display panel 110 may include a plurality of gate lines and a plurality of data lines. The gate line may refer to, for example, a line for transmitting a scan signal or a gate signal, and the data line may refer to, for example, a line for transmitting a data voltage. For example, each of the plurality of sub-pixels included in the display panel 110 may be connected to a gate line and a data line. For example, each of the plurality of data lines may provide data to the same column of pixels. In other words, the display panel 110 may be a panel of a 1D1G stripe structure.

[0070] The display panel 110 can sequentially drive the multiple gate lines, or can drive some of the multiple gate lines simultaneously. For example, the display panel 110 can drive two adjacent gate lines in the multiple gate lines simultaneously. The display panel 110 can be any panel as long as it is a panel with a driving structure capable of driving the multiple gate lines simultaneously.

[0071] The display panel 110 may drive frames of the first resolution at a first frame rate. The first frame rate may be, for example, a maximum frame rate that can be output by the display panel 110. For ease of description, the operating frequency of the display panel 110 and the first frame rate will be used interchangeably in the present disclosure and described below.

[0072] The display panel 110 may be implemented to display one frame within a first time corresponding to a first frame rate. For example, the display panel 110 may display one frame within 1 / 60 seconds. If the display panel 110 is a 60 Hz panel with a resolution of 7680×4320, the display panel 110 may display one frame with a resolution of 7680×4320 within 1 / 60 seconds on a display panel composed of 7680×4320 pixels, and if the display panel 110 is a 60 Hz panel with a resolution of 3840×2160, the display panel 110 may display one frame with a resolution of 3840×2160 within 1 / 60 seconds on a display panel composed of 3840×2160 pixels.

[0073] The first time may be, for example, the time taken until all of the plurality of gate lines included in the display 110 are sequentially driven. For example, if the display panel is a 60 Hz panel with a resolution of 7680×4320, the display panel 110 may drive by driving the gate lines corresponding to the 7680 pixels included in the first row and sequentially driving the gate lines corresponding to the 7680 pixels included in the second row until the gate lines corresponding to the 7680 pixels included in the 4320th row. Through this operation, one frame may be displayed, and the time for displaying one frame may refer to the time taken until all the gate lines included from the first row to the 4320th row are driven.

[0074] However, the embodiment is not limited thereto, and the processor 120 may be configured to control the display panel 110 to drive until the gate lines corresponding to 7680 pixels included in the 4320th row are driven by a method of driving the pixels included in the first row and then driving the pixels included in any row other than the second row. For example, the scanning direction of the display panel 110 may be implemented in an arbitrarily changed form that is not the upper side to the lower side direction of the display panel.

[0075] In the above, the display panel 110 is described as displaying one frame within 1 / 60 s, but the embodiment is not limited thereto, and the time taken for the display panel 110 to display one frame may vary based on the type of the display 110 .

[0076] The display panel 110 may be implemented in various types, such as, for example but not limited to, a liquid crystal display (LCD), an organic light emitting diode (OLED) display, a plasma display panel (PDP), a micro LED, a laser display, VR, glass, etc. In the display, a driving circuit, a backlight unit, etc., which may be implemented in the form of an amorphous silicon (a-si) thin film transistor (TFT), a low temperature polycrystalline silicon (LTPS) TFT, an organic TFT (OTFT), etc., may also be included. The display panel 110 may also be implemented as a touch screen coupled to a touch sensor, a flexible display, a three-dimensional display (3D display), etc.

[0077] The processor 120 may include various processing circuits and control the overall operation of the display device 100. For example, the processor 120 may control the overall operation of the display device by connecting to each configuration of the display device 100. For example, the processor 120 may be configured to control the operation of the display device 100 by connecting to configurations such as, for example, but not limited to, the display panel 110, the communication interface 130, and a memory (not shown). In addition, the processor 120 may include various processing circuits such as, for example, but not limited to, an image processor (e.g., a scaler; not shown) and a timing controller (TCON; not shown), etc., but the configuration may be implemented as a separate configuration, and the processor 120 may be configured to control the operation of the display device 100 by connecting to configurations such as, for example, but not limited to, the image processor, TCON, etc.

[0078] According to an embodiment, the processor 120 may be implemented as, for example, but not limited to, a digital signal processor (DSP), a microprocessor, a time controller (TCON), etc. However, the embodiment is not limited thereto, and the processor 120 may include, for example, but not limited to, one or more of a central processing unit (CPU), a microcontroller unit (MCU), a microprocessing unit (MPU), a controller, an application processor (AP), a communication processor (CP), an ARM processor, etc., or may be defined by corresponding terms. In addition, the processor 120 may be implemented as a system on chip (SOC) or a large-scale integration (LSI) embedded with a processing algorithm, and may be implemented in the form of a field programmable gate array (FPGA).

[0079] The processor 120 may be configured to adjust the received content to a second resolution based on the frame rate of the content received through the communication interface 130 being greater than the first frame rate of the display device 110 , and control the display 110 to display the content of the second resolution at a second frame rate greater than the first frame rate.

[0080] The processor 120 may be configured to control the display panel 110 so that one frame included in the content of the second resolution is displayed within a second time that is less than the first time and corresponds to a second frame rate.

[0081] This operation is possible when the processor 120 repeatedly displays one pixel line included in the content of the second resolution through two adjacent gate lines among the plurality of gate lines.

[0082] In order to describe the above operation, first, the resolution adjustment operation of the processor 120 will be described.

[0083] The processor 120 may adjust the content to the second resolution based on the vertical resolution. For example, based on the display panel 110 being a panel with a resolution of 7680×4320, the processor 120 may adjust the resolution of the content based on the vertical resolution of 4320.

[0084] Equal division may refer to, for example, division into equal sizes, and equal values ​​may refer to, for example, the size of each object based on equal divisions. For example, a 2-division value of 4320 may be 2160, and a 4-division value may be 1080. In addition, the vertical resolution of the display panel 110 may refer to, for example, the number of pixels arranged in the vertical direction of the plurality of pixels included in the display panel 110.

[0085] The processor 120 may adjust the horizontal resolution of the content based on the horizontal resolution of the display panel 110, and adjust the vertical resolution of the content based on the same value of the vertical resolution. For example, the processor 120 may be configured to adjust the horizontal resolution of the content based on the horizontal resolution 7680 and the vertical resolution 4320 based on the same value (e.g., a half-value of 2160) based on the display 110 being a panel with a resolution of 7680×4320.

[0086] For example, the processor 120 may adjust the vertical resolution of the content and adjust the resolution of the content to 7680×2160 based on the display panel 110 being a panel with a resolution of 7680×4320 and the resolution of the content being 7680×4320. The processor 120 may adjust the horizontal resolution of the content and adjust the resolution of the content to 7680×2160 based on the display panel 110 being a panel with a resolution of 7680×4320 and the resolution of the content being 3840×2160. For example, the processor 120 may adjust at least one of the horizontal resolution or the vertical resolution of the content based on equal values ​​of the horizontal resolution and the vertical resolution of the display panel 110. For example, the adjustment of the resolution may be performed by scaling up or scaling down.

[0087] The processor 120 may be configured to control the display panel 110 so that a frame included in the content for which the resolution is adjusted is displayed in a second time that is less than a first time. The first time may be a time taken until all of the plurality of gate lines included in the display panel 110 are sequentially driven.

[0088] In order to describe a method of reducing the time for displaying the first frame, an example using a halved value of the vertical resolution of the display panel 110 will be described.

[0089] The processor 120 may adjust the resolution of the content based on the halved value of the vertical resolution of the display panel 110. For example, based on the resolution of the display panel 110 being 7680×4320 and the resolution of the content being 7680×4320, the processor 120 may adjust the resolution of the content to 7680×2160 based on the halved value 2160 of the vertical resolution of the display panel 110.

[0090] The processor 120 may be configured to control the display panel 110 so that one frame is displayed within the second time based on simultaneously driving two adjacent gate lines among the plurality of gate lines included in the display panel 110. For example, the processor 120 may display one pixel line, which is included in the frame for which the vertical resolution is adjusted, by driving two adjacent gate lines among the plurality of gate lines.

[0091] In the above example, the display panel 110 may include 4320 gate lines, the vertical resolution of the content to be displayed may be 2160, and the processor 120 may display the first pixel line of the content by driving the upper two gate lines of the display panel 110. Then, the processor 120 may drive the lower two gate lines to display the second pixel line. In this way, the processor 120 may sequentially display all pixel lines of the content.

[0092] In the case of conventional technology, the multiple grid lines need to be driven 4320 times in sequence or driven based on the time divided by 4320 times to display one frame. However, in the case of the present disclosure, because two adjacent grid lines are driven simultaneously, the multiple grid lines are driven 2160 times in sequence or driven based on the time divided by 2160 times, and the time to display one frame can be reduced by half. That is, the time to display one frame can be reduced by reducing the vertical resolution of the content. Because the vertical resolution of the content is still a sufficiently high resolution although it is reduced to 2160, the image quality does not actually decline. In other words, the viewer may not notice the decline of image quality too much.

[0093] In the above, the use of a bisection value of the vertical resolution is described, but this is only an example embodiment. The equal values ​​may be different. In addition, the resolution of the content may be adjusted based on a resolution that is lower than the vertical resolution of the display panel 110 and is not the equal value of the vertical resolution of the display panel 110. For example, based on the display panel 110 including 4320 grid lines, the processor 120 may adjust the vertical resolution of the content to 617, and may drive seven continuous grid lines simultaneously. One grid line may remain, and even if the remaining grid line is not driven, the viewer may hardly recognize the remaining one grid line due to very small pixels.

[0094] The processor 120 can be configured to adjust the resolution of the content based on the frame rate of the content being greater than the operating frequency of the display panel 110 and based on the equal value of the vertical resolution, and control the display panel 110 so that a frame included in the content with the adjusted resolution is displayed in a second time that is less than the first time.

[0095] For example, if the display panel 110 is a 50 Hz panel and the frame rate of the content is 100 Hz, or if the display panel is a 60 Hz panel and the frame rate of the content is 120 Hz, the processor 120 may be configured to adjust the resolution of the content based on an equal value of the vertical resolution of the display panel 110, and control the display panel 110 so that a frame included in the content for which the resolution is adjusted is displayed in a second time that is less than the first time.

[0096] The processor 120 may identify the equivalent values ​​of the frame rate of the content and the vertical resolution of the display panel 110 based on the first frame rate. For example, if the frame rate of the content is 120 Hz and the display panel 110 is a 60 Hz panel, the processor 120 may halve the vertical resolution of the display panel 110. Alternatively, if the frame rate of the content is 240 Hz and the display 110 panel is a 60 Hz panel, the processor 120 may quaternize the vertical resolution of the display panel 110. That is, based on inputting content having the same resolution as the resolution of the display panel 110, the processor 120 may perform scaling down on the vertical resolution of the content to correspond to a halved value or a quadrangular value of the vertical resolution of the display panel 110 based on the frame rate of the content and the operating frequency of the display panel 110.

[0097] By controlling the display panel 110 so that a plurality of frames included in the content for which the resolution is adjusted are displayed within the first time, the processor 120 can output content corresponding to the frame rate of the content. For example, if the frame rate of the content is 120Hz and the display panel 110 is a 60Hz panel, a conventional display device will omit a portion of the frames of the content and display a frame included in the content within the first time, i.e., within 1 / 60 seconds. On the other hand, the processor 120 of the present disclosure can adjust the resolution of the content based on the bisection value of the vertical resolution of the display panel 110, and control the display panel 110 so that a frame included in the content for which the resolution is adjusted is displayed within the second time, for example, within 1 / 120 seconds. The processor 120 can display two frames included in the content within the first time, for example, within 1 / 60 seconds, and this can, for example, refer to the content being displayed as a frame corresponding to the content.

[0098] The processor 120 may be configured to adjust the content to the second resolution if the content is of the first type, and to control the display panel 110 to display at the first frame rate without adjusting the resolution of the content if the content is of the first type.

[0099] The processor 120 can adjust the resolution of the content and control the display panel 110 so that a frame is displayed within a second time based on the frame rate of the content being greater than the operating frequency of the display panel 110 and the type of the content being the first type, and control the display panel 110 so that only a portion of the multiple frames included in the content are displayed based on the operating frequency of the display panel 110 based on the frame rate of the content being greater than the operating frequency of the display panel 110 and the type of the content being the second type.

[0100] For example, the processor 120 can adjust the resolution of the content and control the display panel 110 so that a frame is displayed within the second time based on the fact that the frame rate of the content is greater than the operating frequency of the display panel 110 and the type of the content is game content, and control the display panel 110 so that only a portion of the multiple frames included in the content are displayed based on the operating frequency of the display panel 110 based on the fact that the frame rate of the content is greater than the operating frequency of the display panel 110 and the type of the content is another content that is not a game, such as a moving image.

[0101] However, the embodiment is not limited thereto, and the playback method of the content may be determined based on a user command, regardless of the type of the content. For example, the processor 120 may adjust the received content to a second resolution based on a user command for increasing the frame rate of the input. The processor 120 may display the content at a first frame rate without adjusting the resolution of the content based on a user command for reducing the response rate or changing to the original mode of the input. The processor 120 may be configured to control the display panel 110 so that only a portion of the multiple frames included in the content are displayed based on the first frame rate.

[0102] According to an embodiment, the above-mentioned user commands may be provided to the user in the form of a dedicated menu such as, for example but not limited to, a game mode, a sports mode, etc.

[0103] The processor 120 may also identify a playback method of the content based on whether upscaling of the received content is performed.

[0104] The content may be, for example, content on which upscaling is performed before being stored in the display device 100. For example, the original content may be upscaled to 3840×2160 resolution or 7680×4320 resolution by a server or the like, and the display device 100 may receive and store the content on which upscaling is performed to 7680×4320 resolution.

[0105] The processor 120 may adjust a vertical resolution of the upscaled content based on a frame rate of the upscaled content, and control the display panel 110 so that a frame included in the content for which the vertical resolution is adjusted is displayed in a second time that is less than the first time.

[0106] For example, the display panel 110 may be a 60 Hz panel with a resolution of 7680×4320, and the frame rate of the content that is scaled up to a resolution of 7680×4320 may be 120 Hz. The processor 120 may be configured to control the display panel 110 by adjusting the resolution of the scaled-up content to 7680×2160 and simultaneously driving two adjacent gate lines among the multiple gate lines so that a frame included in the content is displayed within the second time.

[0107] The display panel 110 may be a 120 Hz panel with a resolution of 7680×4320, and the frame rate of the content that is scaled up to a resolution of 7680×4320 may be 240 Hz. The processor 120 may be configured to control the display panel 110 so that a frame included in the content is displayed within the second time by adjusting the resolution of the scaled-up content to 7680×2160 and simultaneously driving one gate line or two adjacent gate lines among the plurality of gate lines.

[0108] As described above, when up-scaled content is used, although the vertical resolution of the content is adjusted, a decrease in image quality may not occur because the up-scaled content corresponds to the vertical resolution of the original content.

[0109] The processor 120 may identify whether the adjustment of the resolution of the content and the driving method of the plurality of gate lines are performed based on at least one of the additional information or the image analysis of the content.

[0110] For example, the processor 120 may be configured to adjust the resolution of the content based on a frame rate of the content and an operating frequency of the display panel 110 if the content is identified as scaled-up content based on at least one of the additional information or an image analysis of the content, and to control the display panel 110 so that a frame included in the content for which the resolution is adjusted is displayed in a second time that is less than the first time.

[0111] The processor 120 may be configured such that the vertical resolution of the content may be maintained in a state larger than the vertical resolution of the original content.

[0112] For example, the original content may be a resolution of 3840×2160, the scaled-up content may be a resolution of 7680×4320, the frame rate of the original content and the scaled-up content may be 240 Hz, and the display panel 110 may be a 60 Hz panel with a resolution of 7680×4320. In this example, if the processor adjusts the resolution of the scaled-up content to 7680×1080, the resolution of the scaled-up content may be adjusted to 7680×2160 because the adjusted resolution may be lower than the vertical resolution of the original content. Because the vertical resolution of the scaled-up content is divided into two equal parts, the processor 120 may simultaneously drive two adjacent gate lines of the plurality of gate lines and display one frame within 1 / 120 s. However, because the frame rate is 240 Hz, the processor 120 may not display some frames of the content for which the resolution is adjusted as corresponding to the operating frequency of the display panel 110.

[0113] Through this operation, the response characteristics can be improved without degrading the image quality of the content.

[0114] However, the embodiment is not limited thereto, and the above-mentioned method of adjusting the resolution and the method of not displaying some frames may be negotiated into various forms.

[0115] In the above, it is described that the frame rate of the content is greater than the first frame rate, but the embodiment is not limited to this. Based on the frame rate of the content being the same as the first frame rate, the processor 120 can increase the frame rate of the content by performing frame interpolation on the content, and adjust the content with the increased frame rate to the second resolution.

[0116] The processor 120 may perform image processing on the content received through the communication interface 130 and display the image-processed content through the display panel 110. The processor 120 may also perform image processing on the content streamed through the communication interface 130 and display the image-processed content through the display panel 110.

[0117] The communication interface 130 may include various communication circuits and may be configured to communicate with various types of external devices according to various types of communication methods. The communication interface 130 may include, for example but not limited to, a Wi-Fi module, a Bluetooth module, an infrared communication module, a wireless communication module, etc. Each communication module may be implemented with at least one hardware chip type.

[0118] The processor 120 may communicate with various external devices using the communication interface 130. The external devices may include, for example but not limited to, a server, a Bluetooth headset, a display device, and the like.

[0119] The Wi-Fi module and the Bluetooth module can communicate using the Wi-Fi method and the Bluetooth method, respectively. When using the Wi-Fi module or the Bluetooth module, various connection information such as a service set identifier (SSID) and a session key can be first sent and received, and after using it for communication connection, various information can be sent and received.

[0120] The infrared communication module may communicate according to the Infrared Data Association (IrDA) technology which wirelessly transmits data at a short distance using infrared rays between visible rays and millimeter waves.

[0121] The wireless communication module may include at least one communication chip that communicates according to various communication standards other than the above-mentioned communication methods, such as ZigBee, third generation (3G), third generation partnership project (3GPP), long term evolution (LTE), advanced LTE (LTE-A), 4th generation (4G), 5th generation (5G), etc.

[0122] The other communication interface 130 may include, for example but not limited to, at least one of a wired communication module for communicating using a local area network (LAN) module, an Ethernet module, a pair cable, a coaxial cable, an optical cable, and the like.

[0123] The communication interface 130 may also include an input / output interface. The input / output interface may be at least one of a High Definition Multimedia Interface (HDMI), a Mobile High Definition Link (MHL), a Universal Serial Bus (USB), a DisplayPort (DP), a Thunderbolt interface (Thunderbolt), a Video Graphics Array (VGA) port, an RGB port, a D-SUB, or a Digital Visual Interface (DVI).

[0124] The input / output interface may input or output at least one of an audio signal and a video signal.

[0125] According to an embodiment, the input-output interface may include a port for inputting and outputting only an audio signal and a separate port for inputting and outputting only a video signal, or may be implemented as one port for inputting and outputting both an audio signal and a video signal.

[0126] exist Figure 2A In , the processor 120 is described as adjusting the resolution of the content and controlling the plurality of gate lines included in the display device 110. Figure 2A In the embodiment, although the processor 120 is described as including a scaler for adjusting the resolution of the content and a time controller (TCON) for controlling the plurality of gate lines included in the display panel 110, the embodiment is not limited thereto, and other embodiments will be described below.

[0127] Figure 2B is a block diagram illustrating an example configuration of a display device 100 according to an embodiment of the present disclosure.

[0128] Reference Figure 2B , the display device 100 may also include not only a display panel 110, a processor (e.g., including a processing circuit) 120 and a communication interface (e.g., including a communication circuit) 130, but also a memory 140, a user interface (e.g., including a user interface circuit) 150, an image processor (e.g., including an image processing circuit) 160 (e.g., a scaler) and a timing controller (TCON) 170. It may not be repeated here. Figure 2B The configuration of Figure 2A The description of the configuration that the configuration overlaps.

[0129] The memory 140 may store content. The processor 120 may perform image processing on the content stored in the memory 140 and display it through the display panel 110. In addition, the memory 140 may store information for displaying other content.

[0130] The memory 140 may be implemented as a nonvolatile memory and / or a volatile memory, but is not limited thereto. For example, a hard disk may be used instead of the memory, and any configuration is possible if the configuration can store data.

[0131] The user interface 150 may include various user interface circuits and receive various user interactions. The user interface 150 may be implemented in various forms based on the embodiment of the display device 100. For example, the user interface 150 may include a button provided on the display device 100, a microphone for receiving a user's voice, a camera for detecting user motion, etc. If the display device 100 is implemented as a touch-based terminal device, the user interface 150 may be implemented in the form of a touch screen including an interlayer structure with a touch pad. The user interface 150 may be a configuration of the above-mentioned display panel 110.

[0132] The image processor 160 may include various image processing circuits and adjust the resolution of the content by controlling the processor 120. For example, the image processor 160 may perform scaling up or scaling down on the content by controlling the processor 120. The image processor 160 may change the resolution of the content. For example, the image processor 160 may adjust content having a 16:10 resolution to 16:5 content.

[0133] The timing controller 170 may include various timing control circuits and receive input signals (IS), horizontal synchronization signals (Hsync), vertical synchronization signals (Vsync), main clock signals (MCLK), etc. from an external configuration (e.g., the processor 120), and generate image data signals, scan control signals, data control signals, emission control signals, etc. to provide to the display panel 110.

[0134] The communication interface 130, the memory 140, the user interface 150, the image processor 160 and the timing controller 170 may be implemented as one configuration, or only some of the configurations may be implemented as one configuration. In addition, at least one of the communication interface 130, the memory 140, the user interface 150, the image processor 160 or the timing controller 170 may be implemented in a form integrated with the display panel 110.

[0135] and Figure 2A and Figure 2B Differently, the display device 100 may also be simply implemented in the form of a display panel 110 including the time controller 170 .

[0136] Figure 2C is a diagram showing an example configuration of the display panel 110 according to an embodiment of the present disclosure.

[0137] The display panel 110 may be formed such that the gate lines (GL1 to GLn) and the data lines (DL1 to DLm) intersect each other, and R sub-pixels, G sub-pixels, B sub-pixels (e.g., PR, PG, and PB) may be formed in an area provided by the intersection thereof. Adjacent R sub-pixels, G sub-pixels, B sub-pixels (e.g., PR, PG, and PB) may form one pixel. In other words, each pixel may reproduce the color of the subject with three primary colors of red (R), green (G), and blue (B) by including an R sub-pixel (PR) presenting red (R), a G sub-pixel (PG) presenting green (G), and a B sub-pixel (PB) presenting blue (B).

[0138] If the display panel 110 is implemented as an LCD panel, each sub-pixel (e.g., PR, PG, and PB) may include a pixel electrode and a common electrode, and as the liquid crystal arrangement changes an electric field formed by a potential difference between the two electrodes, light transmittance may change. TFTs formed at intersections of the gate lines (GL1 to GLn) and the data lines (DL1 to DLm) may provide video data (i.e., red (R), green (G), and blue (B) data) from the data lines (DL1 to DLm) to the pixel electrodes of each sub-pixel (e.g., PR, PG, and PB) in response to a scan pulse from each gate line (GL1 to GLn).

[0139] The display panel 110 may further include a backlight unit 111 , a backlight driver 112 , and a panel driver 113 .

[0140] The backlight driver 112 may be implemented in the form of a driver integrated circuit (IC) for driving the backlight unit 111. According to an embodiment, the driver IC may be implemented as hardware separate from the processor 120. In addition, if the light source included in the backlight unit 111 is implemented as an LED device, the driver IC may be implemented as at least one LED driver that controls the current applied to the LED device. According to an embodiment, the LED driver may be provided at the rear end of a power supply (e.g., a switch mode power supply (SMPS)) and receive a voltage applied from the power supply. However, according to another embodiment, the voltage may be received from a separate power supply. It is also possible to implement the SMPS and the LED driver in the form of an integrated module.

[0141] The panel driver 113 may be implemented in the form of a driver IC for driving the display panel 110. According to an embodiment, the driver IC may be implemented as hardware separate from the processor 120. For example, the panel driver 113 may include a data driver 113-1 that provides video data to data lines and a gate driver 113-2 that provides scan pulses to gate lines.

[0142] As a method of generating a data signal, the data driver 113-1 may receive image data of R / G / B components from the processor 120 or the timing controller 170 and generate a data signal. In addition, the data driver 113-1 may be connected to the data lines (DL1, DL2, DL3, . . . and DLm) of the display panel 110 and apply the generated data signal to the display panel 110.

[0143] The gate driver 113-2 (or scan driver) may be connected to the gate lines (GL1, GL2, GL3, . . . GLn) to generate gate signals (or scan signals) and transmit the gate signals to specific rows of the display panel 110. In the pixels to which the gate signals are transmitted, the data signals output from the data driver 113-1 may be transmitted.

[0144] The processor 120 may control the gate driver 113-2 and drive at least two gate lines at the same time. For example, the processor 120 may transmit a signal to at least one of the data driver 113-1 or the gate driver 113-2 and control the display panel 110. Through this operation, the display time of the frame is reduced, and the content may be displayed at a frame rate higher than the operating frequency of the display panel 110.

[0145] The operation of the processor 120 will be described in more detail below through various drawings. The respective embodiments in the following drawings can be implemented individually or in combination.

[0146] Figure 3A , Figure 3B , Figure 3C , Figure 3D and Figure 3E is a diagram illustrating an example driving method of the display panel 110 according to an embodiment of the present disclosure.

[0147] The display panel 110 may be implemented as a panel with an x×y resolution. For example, the display panel 110 may be implemented as a panel with a 7680×4320 resolution. The display panel 110 may also be implemented as a panel with a 3840×2160 resolution. However, this is merely an example embodiment, and the display device 110 may be implemented with various other resolutions. In addition, the ratio of the horizontal length to the vertical length of the display panel 110 may also vary, such as 21:9, 32:9, etc.

[0148] Figure 3A The display panel 110 implemented as a panel of x×y resolution is shown, and for convenience of description, only the vertical resolution is shown in a divided state. For example, the display panel 110 implemented as a panel of x×y resolution may be divided into horizontally long areas by the number y.

[0149] A number y of horizontally long areas may be driven by the gate lines. For example, the display panel 110 may include a number y of gate lines.

[0150] According to an embodiment, Figure 3B is a diagram showing the operating frequency of the display panel 110 according to an embodiment of the present disclosure. Figure 3B In the embodiment, the display panel 110 may be a 60 Hz panel.

[0151] like Figure 3B As shown, the display panel 110 can display 60 frames in 1 second. For example, the display panel 110 can display 1 frame in 1 / 60 second.

[0152] The display panel 110 can sequentially drive y number of gate lines to display 1 frame in 1 / 60 seconds. If one gate line is driven at a time, the unit time of driving one gate line may be 1 / (60×y)s, and if all gate lines are driven, it may take 1 / 60 seconds because it is repeated y times.

[0153] According to an embodiment, if two gate lines are driven simultaneously, the unit time may be 1 / (60×y)s, but because the number of repetitions for driving all gate lines is y / 2 times, it may take 1 / 120 seconds.

[0154] In addition, when two gate lines are driven simultaneously, pixels adjacent to each other in the vertical direction can display the same color as each other. For example, in order to make pixels adjacent to each other in the vertical direction display the same color as each other, the display panel 110 can be implemented as follows: Figure 3C The panel of the 1D1G stripe structure shown in FIG. The gate terminals of the pixels adjacent to each other in the vertical direction can be turned on at the same time, and two pixels adjacent to each other in the vertical direction can display the same color because the same data value is input.

[0155] On the other hand, Figure 3D The 1D1G cross-structured panel or Figure 3E In the case of a panel with a 2DHG structure, even when the first gate line and the second gate line are driven simultaneously, two pixels adjacent in the vertical direction may display different colors because the data values ​​input to the pixels adjacent in the vertical direction are different, and the present disclosure may not be applied. However, even in the case of a panel with a 1D1G cross structure or a panel with a 2DHG structure, if it is a technology capable of displaying the same color by simultaneously driving pixels adjacent in the vertical direction, the present disclosure may be applied.

[0156] Figure 4A , Figure 4B and Figure 4C is a diagram showing an example operation of displaying content according to an embodiment of the present disclosure. Figure 4A , Figure 4B and Figure 4C In the embodiment, the display panel 110 may be a 60 Hz panel, and the frame rate of the content may be 120 Hz.

[0157] The processor 120 may adjust the resolution of the content based on the value of the vertical resolution of the display panel 110. For example, Figure 4A As shown, the processor 120 may adjust the resolution of the content to 7680×2160 based on the display panel 110 being a panel with a resolution of 7680×4320.

[0158] The processor 120 may simultaneously drive two adjacent gate lines among the plurality of gate lines included in the display panel 110. For example, Figure 4B As shown, the processor 120 can display the first row of pixel lines for the content whose resolution is adjusted to 7680×2160 by driving the two adjacent gate lines 410 at the upper end. Then, the processor 120 can display the second row of pixel lines for the content whose resolution is adjusted to 7680×2160 by driving the next two adjacent gate lines 420 at the upper end.

[0159] By this method, the processor 120 can reduce the time used to display a frame by half. For example, the processor 120 can be based on not performing the following steps: Figure 4A and Figure 4B The operation in the display frame is 1 / 60 seconds, such as Figure 4C On the other hand, the processor can be based on executing Figure 4A and Figure 4B The operation in the display frame in 1 / 120 seconds, such as Figure 4C That is, the processor 120 can display two frames within 1 / 60 seconds.

[0160] The processor 120 may be Figure 4C In the upper case, 60 frames are displayed in 1 second, but in Figure 4C For example, the processor 120 can reduce the time of displaying one frame by reducing the vertical resolution while keeping the driving speed of the gate lines of the display panel 110 unchanged, and provide an effect that the frame rate seems to be improved.

[0161] Figure 5A and Figure 5B is a diagram showing an example method of adjusting resolution according to an embodiment of the present disclosure. Figure 5A and Figure 5B In the embodiment, the display panel 110 may be an AV panel with an x×y resolution.

[0162] The processor 120 may adjust at least one of the horizontal resolution or the vertical resolution of the content based on equal values ​​of the horizontal resolution and the vertical resolution of the display panel 110 .

[0163] For example, Figure 5A As shown in FIG. 1 , if the resolution of the content is x×y and the frame rate is 2A Hz, the processor 120 may adjust the resolution of the content to x×y / 2. Figure 5B As shown, if the resolution of the content is x / 2×y / 2 and the frame rate is 2 Hz, the processor 120 may adjust the resolution of the content to x×y / 2.

[0164] If the display panel 110 is a 60 Hz panel with a resolution of 7680×4320, the resolution of the content is 7680×4320 and the frame rate is 120 Hz, the processor 120 may adjust the resolution of the content to 7680×2160. If the display panel 110 is a 60 Hz panel with a resolution of 7680×4320, the resolution of the content is 3840×2160 and the frame rate is 120 Hz, the processor may adjust the resolution of the content to 7680×2160.

[0165] If the resolution of the content is x×y and the frame rate is 4A Hz, the processor 120 may adjust the resolution of the content to x×y / 4. For example, if the display panel is a 60 Hz panel with a resolution of 7680×4320, the resolution of the content is 7680×4320 and the frame rate is 240 Hz, the processor 120 may adjust the resolution of the content to 7680×1080. That is, based on the frame rate of the content and the operating frequency of the display panel 110, the scaling ratio of the content may be changed.

[0166] If the resolution of the content is x / 4×y / 4 and the frame rate is 2A Hz, the processor 120 may adjust the resolution of the content to x×y / 2. For example, if the display panel 110 is a 60 Hz panel with a resolution of 7680×4320, the resolution of the content is 1920×1080 and the frame rate is 120 Hz, the processor 120 may adjust the resolution of the content to 7680×2160.

[0167] If the resolution of the content is 2x×2y and the frame rate is 2 Hz, the processor 120 may adjust the resolution of the content to x×y / 2.

[0168] For example, the processor 120 may adjust the horizontal resolution of the content to correspond to the horizontal resolution of the display panel 110 , and adjust the vertical resolution of the content to correspond to an equivalent value of the vertical resolution of the display panel 110 .

[0169] Fig. 6A , Figure 6B and Figure 6C 1 is a diagram showing an example configuration of the processor 120 according to an embodiment of the present disclosure. Fig. 6A , Figure 6B and Figure 6C In the embodiment, the display panel 110 may be a 60 Hz panel with a resolution of 7680×4320.

[0170] The processor 120 may include an image processor (scaler) for adjusting the resolution of the content and a timing controller (TCON) for generating an input signal on the display panel 110. The image processor and the timing controller may be implemented as separate ICs. The timing controller may be included in the display panel 110.

[0171] The figure shows the conventional technology. Fig. 6A In the embodiment, the image processor may adjust the content having a resolution of 3840×2160 at 60 Hz to a resolution of 7680×4320 based on the resolution of the display panel 110. Then, the timing controller may output the content having a resolution of 7680×4320 at 60 Hz as it is, and the display panel 110 may output the content at 60 Hz and at a resolution of 7680×4320.

[0172] In the figure which also shows the conventional technology Figure 6B In the embodiment, the image processor may adjust the content having a resolution of 3840×2160 at 120 Hz to a frame rate of 60 Hz and a resolution of 7680×4320 based on the operating frequency and resolution of the display panel 110. Then, the timing controller may output the content having a resolution of 7680×4320 at 60 Hz as is, and the display panel 110 may output the content at 60 Hz and at a resolution of 7680×4320.

[0173] FIG. 1 is a diagram showing an example embodiment of the present disclosure. Figure 6C In the embodiment, the image processor may adjust the content having a resolution of 3840×2160 at 120 Hz to a frame rate of 120 Hz and a resolution of 7680×2160 based on the operating frequency and resolution of the display panel 110. Then, the timing controller may output the content having a resolution of 7680×2160 at 120 Hz at a frame rate of 120 Hz and a resolution of 7680×2160, and the display panel 110 may output the content at 120 Hz and a resolution of 7680×4320 by simultaneously driving two adjacent gate lines.

[0174] Figure 7 is a diagram illustrating an example method of outputting content at various frame rates according to an embodiment of the present disclosure.

[0175] In the above, for convenience of description, the use of a halved value of the vertical resolution of the display panel 110 is described, but the embodiment is not limited thereto.

[0176] For example, if the display panel is a 60 Hz panel with a resolution of 7680×4320 and content with a resolution of 7680×4320 at 180 Hz is played back, the processor 120 may adjust the resolution of the content to 7680×1440 and display one pixel line by simultaneously driving three adjacent gate lines 710 included in the display panel 110, as shown in FIG. Figure 7 shown.

[0177] For example, by simultaneously driving three adjacent gate lines 710, the time for displaying one frame can be reduced from 1 / 60s to 1 / 180s. The display panel 110 can display 180 frames for 1 second.

[0178] The operation may be performed variously based on the frame rate of the content. For example, if the display panel 110 is a 60 Hz panel with a resolution of 7680×4320 and content with a resolution of 7680×4320 at 240 Hz is played back, the processor 120 may adjust the resolution of the content to 7680×1080 and display one pixel line by simultaneously driving four adjacent gate lines included in the display panel 110. The display panel 110 may display 240 frames in 1 second.

[0179] exist Figure 7 In the embodiment, the method of adjusting the resolution and identifying the number of gate lines that can be driven simultaneously is described based on the operating frequency of the display panel 110 and the frame rate of the content, but the embodiment is not limited thereto. For example, the method of adjusting the resolution and the number of gate lines that can be driven simultaneously can be based on at least one of a user command or a content type.

[0180] For example, if the display panel is a 60 Hz panel with a resolution of 7680×4320 and content with a resolution of 7680×4320 at 240 Hz is being played back, the processor 120 may adjust the resolution of the content to 7680×1080 based on the first user command being input, and simultaneously drive four adjacent gate lines included in the display panel 110 and display one pixel line. The content may be displayed at 240 Hz.

[0181] The processor 120 may adjust the resolution of the content to 7680×2160 based on the second user command being input, and simultaneously drive two adjacent gate lines included in the display panel 110 to display one pixel line. The processor 120 may display the content at 120 Hz by displaying only a portion of the plurality of frames included in the content.

[0182] Figure 8 is a flowchart illustrating an example method of controlling a display device according to an embodiment of the present disclosure.

[0183] Receive content (S810). Adjust the received content to a second resolution (S820) based on a frame rate of the received content being greater than a first frame rate of the display panel. Display the content of the second resolution at a second frame rate greater than the first frame rate (S830). The display panel may drive frames of the first resolution at the first frame rate.

[0184] The display panel may include a plurality of gate lines and a plurality of data lines, and each of the plurality of data lines may provide data to pixels in the same column, and the displaying (S830) may include simultaneously driving two adjacent gate lines of the plurality of gate lines.

[0185] The displaying (S830) may include repeatedly displaying one pixel line included in the content of the second resolution through two adjacent gate lines among the plurality of gate lines.

[0186] The display panel may display one frame within a first time corresponding to a first frame rate, and the displaying (S830) may include displaying one frame included in the content of the second resolution within a second time that is less than the first time and corresponds to a second frame rate.

[0187] The adjusting (S820) may include adjusting the received content to a second resolution based on an equivalent value of a vertical resolution of the display panel.

[0188] The adjusting ( S820 ) may include adjusting a horizontal resolution of the content based on a horizontal resolution of the display panel and adjusting a vertical resolution of the content based on an equal value of a vertical resolution of the display panel.

[0189] This may further include identifying an equivalent value of a vertical resolution of the display panel based on the first frame rate and the frame rate of the content.

[0190] The first frame rate may be a maximum frame rate that the display panel can output, and the vertical resolution of the display panel may be the number of pixels arranged in a vertical direction among the plurality of pixels included in the display panel.

[0191] Adjusting and displaying (S820, S830) may include adjusting the content to the second resolution and displaying it at the second frame rate based on the content being the first type, and not adjusting the resolution of the content and displaying it at the first frame rate based on the content being the second type.

[0192] Based on the frame rate of the content being the same as the first frame rate, it may further include performing frame interpolation on the content to increase the frame rate of the content, and adjusting (S820) may include adjusting the content for which the frame rate is increased to the second resolution.

[0193] The adjusting ( S820 ) may include adjusting the received content to the second resolution based on a user command to increase the frame rate being input.

[0194] According to various embodiments as described above, the display device can improve response characteristics by adjusting the resolution of the frame to reduce the time for displaying the frame.

[0195] Furthermore, since the display device can operate at a relatively low operating frequency compared to the frame rate of the content, the display device can be implemented at a low cost.

[0196] By producing content at a high resolution, although the vertical resolution of the content is reduced by half, the image quality perceived by the user does not deteriorate significantly, and by improving the response characteristics, a smoother image can be output.
