Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of video display optimization, and particularly relates to a structure, a method and a display device for display optimization based on HSR+FRC technology. BACKGROUND

[0002] In the field of display technology, refresh rate and color performance are core indicators for measuring display effect, which directly affect the visual experience of users. At present, most TV manufacturers have launched products supporting HSR (High Refresh Rate) technology. This technology improves the screen refresh rate by reducing the vertical resolution. For example, the display specification of 4K2K60Hz can be extended to 4K1K120Hz. In the scene of e-sports games and other scenes with extremely high requirements for refresh rate, the smoothness and clarity of the picture can be significantly enhanced, and a more immersive experience can be brought to users.

[0003] However, HSR technology has obvious limitations in daily video watching scenarios. At present, the content provided by digital television (DTMB), IPTV set-top boxes and various network video platforms is mostly 2K resolution and has a refresh rate of only 30Hz or 60Hz. Real 4K video sources are extremely rare. When playing such low-resolution and low-refresh-rate video sources, the excessively high refresh rate provided by HSR technology cannot be effectively utilized, which not only causes waste of resources of the display device, but also increases unnecessary power consumption, and even may shorten the service life of the device.

[0004] At the same time, HSR technology also has problems in color performance. Traditional 8bit screens cannot finely present rich color levels due to limited color depth, resulting in harsh and unnatural pictures in color transition areas. Although some high-end screens use 10bit or 12bit higher bit depth to present more vivid and realistic color effects, such screens are expensive and difficult to popularize due to cost constraints, and cannot meet the needs of the general public for high cost-effective display effect.

[0005] Therefore, the present application proposes a display optimization method based on HSR+FRC (Frame Rate Control) technology. Through the cooperative application of the two technologies, the color performance of 8bit screens is improved while avoiding the waste of resources of HSR technology, so that better display effect is realized at a lower cost to meet the needs of users in different scenarios. SUMMARY

[0006] In view of the above problems, the present application aims to provide a structure, a method and a display device for display optimization based on HSR+FRC technology, to solve the problems of resource waste and insufficient color performance of HSR technology when playing low-resolution and low-refresh-rate video sources.

[0007] The object of the present application can be achieved by the following technical solutions:

[0008] The first aspect is a structure for display optimization based on HSR+FRC technology, comprising:

[0009] An SOC module receives each channel video signal for analysis and processing, and identifies whether the FRC condition is met, and outputs a standard protocol signal, and reserves an HSR identification signal;

[0011] As a further aspect of the present application, the HSR identification signal is a GPIO high-low level signal or an IIC instruction code.

[0012] As a further aspect of the present application, the display mode includes a Normal mode, an HSR mode and an HSR+FRC mode.

[0013] As a further aspect of the present application, a self-developed SOC chip is configured in the SOC module, and the SOC chip supports HSR technology and FRC technology.

[0014] When the refresh rate of the input video signal is 30Hz and the display mode is HSR120Hz, the FRC function is enabled; or when the refresh rate of the input video signal is 60Hz and the display mode is HSR240Hz, the FRC function is enabled.

[0015] As a further aspect of the present application, the video signal includes a video signal of HDMI, DTMB, LAN or USB video source.

[0016] The second aspect is a method for display optimization based on HSR+FRC technology, comprising the steps of:

[0017] S1, according to the video signal and user demand, it is judged whether HSR needs to be started, if not, Normal display mode is entered, if yes, HSR display mode is entered for identification;

[0018] S2, it is judged whether the FRC starting condition is met, if not, HSR display mode is entered, if yes, HSR+FRC mode is entered.

[0019] The third aspect is a display device which adopts the display optimization structure based on HSR+FRC technology of the first aspect for display optimization.

[0020] The present application has the following advantages:

[0028] The embodiments of the present application will be described in detail below, and the examples of the embodiments are shown in the drawings, wherein the same or similar symbols represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present application, and cannot be understood as a limitation of the present application.

[0029] The existing HSR technology application has the following problems: 1. When the HSR technology plays a low-resolution (mostly 2K) and low-refresh-rate (30Hz or 60Hz) video source, the high refresh rate cannot play a value, causing resource waste, power consumption increase, and even shortening the service life of the device; 2. The color transition of the traditional 8bit screen is harsh due to the limited color depth, and the 10bit, 12bit and other high color depth screens are difficult to popularize due to high cost, and cannot meet the needs of the public for high cost performance and high quality display effect.

[0030] To solve the above problems, the application discloses a structure, method and display device for display optimization based on HSR+FRC technology.

[0031] Embodiment 1

[0032] The embodiment discloses a structure for display optimization based on HSR+FRC technology, as shown in Figure 1 The structure mainly includes a SOC module, a TCON module and a PANEL display screen, wherein:

[0033] The SOC module is used for receiving and analyzing and processing each channel video signal, and identifying whether the FRC condition is met, and outputting a standard protocol signal, and reserving an HSR identification signal.

[0034] As shown in Figure 1 Each channel video signal can be a video signal of HDMI, DTMB, LAN or USB video source; the video signal includes a 2K or 4K video signal.

[0035] The SOC module is configured with a self-developed SOC chip, and the SOC chip refers to a display control (SOC) chip, which can receive input video signals and analyze and process the refresh rate and color information of the video signals in real time.

[0036] The self-developed SOC chip of the application supports HSR technology and FRC technology, can intelligently identify the resolution and refresh rate of the input video signal, and can intelligently call the HSR technology according to the actual situation of the video signal and the user demand, so as to avoid resource waste and power consumption increase.

[0037] For example, when it is detected that the input video signal is a 4K resolution or the user has no HSR demand, the SOC module automatically closes the HSR technology.

[0038] For another example, when it is detected that the input video signal is a 2K resolution or below or the user adopts a game mode or the user has an HSR demand, the SOC module automatically opens the HSR technology, which will improve the refresh rate of the screen display to improve the smoothness of the picture.

[0039] Further, when in the HSR display mode, the SOC module identifies whether the input video signal state meets the condition for starting FRC, and if the condition for starting FRC is met, the SOC module starts the FRC function, which can change from the frame repetition mode to the FRC (frame rate control) processing mode, to improve the color depth effect.

[0040] The frame repetition mode refers to that when the HSR mode does not meet the FRC condition, the frame repetition mode is adopted.

[0041] Taking the 60Hz-HSR120Hz LCD scheme as an example, when the input signal source refresh rate is 30Hz, under the condition that the HSR is not enabled by default, the SOC generally adopts the 2-frame repetition mode to generate the DATA signal to match the normal refresh rate 60Hz of the LCD. When the HSR is enabled, the refresh rate of the LCD is increased to 120Hz, and if the FRC function is not started, each frame of the original 30Hz picture will be displayed 4 times (30Hz x 4 = 120Hz) to match the refresh rate 120Hz of the LCD. In this state, although the refresh rate is increased, the color performance cannot be improved, and the color transition of the picture is still limited by the original bit depth of the picture source and the screen itself (such as the harsh transition problem of the 8bit screen).

[0042] The FRC processing mode is to insert transition frames optimized by an algorithm between adjacent frames, use the visual persistence effect of the human eye, and make the 8bit screen simulate higher bit depth (such as close to 10bit) color performance.

[0043] For example, when the input signal source refresh rate is 30Hz, the system works in the HSR mode 120Hz state, and meets the 4-frame FRC starting requirement, the 4-frame FRC will generate 3 transition frames for the 30Hz original frame to form a 120Hz display frame sequence with the original frame, so as to make the color transition more natural and delicate, and solve the problem of insufficient color levels of the 8bit screen.

[0044] Further, the SOC chip also has powerful processing capability, which can quickly analyze and process various video signals to ensure the stability and quality of the display picture.

[0045] The TCON module is connected with the SOC module, is used for receiving the standard protocol signal (VBY1 for a 4K television) of the SOC module, and can identify the HSR signal to enter the corresponding display mode, convert the standard protocol signal into the P2P signal of the display screen, and generate the GOA signal to light up the screen.

[0046] The TCON module can ensure that the HSR signal can be correctly applied through accurate identification and processing. When the SOC module improves the refresh rate of the video signal through the HSR technology, the TCON module can quickly respond to reflect this change on the display picture.

[0047] Preferably, when the SOC module interacts with the TCON module to control the HSR technology to turn on or off, the transmission mode of the HSR identification signal includes:

[0048] One is realized through the GPIO interface, usually through the way of pulling up or pulling down the level of the GPIO interface, to deliver the control signal of HSR turning on or off to the TCON module, to inform the TCON module to enter the corresponding working mode.

[0049] The other is to send instruction code through IIC, the SOC module encodes the control instruction of HSR and transmits it to the TCON module through the IIC bus. After receiving the instruction code, the TCON module parses the instruction and adjusts its working state according to the instruction content, thereby realizing intelligent control of the HSR technology.

[0050] This dual-mode signal transmission mode not only improves the flexibility and stability of signal transmission, but also ensures that the HSR technology can accurately and quickly respond to the instructions of the SOC module, providing users with a smoother and clearer display experience.

[0051] Embodiment 2:

[0052] Based on the structure of Embodiment 1, this embodiment discloses a method for display optimization based on HSR+FRC technology, as shown in Figure 2 , which includes:

[0053] First, the system determines whether HSR needs to be turned on according to the video signal and user demand. If not, it enters the Normal display mode; if so, it enters the HSR display mode identification.

[0054] Then, it determines whether the FRC turning-on condition is met. If not, it enters the HSR display mode; if so, it enters the HSR+FRC mode.

[0055] In this embodiment, the display modes include Normal mode, HSR mode and HSR+FRC mode.

[0056] When the HSR switch in the system menu is not turned on, the system defaults to Normal mode to play the picture. The display resolution and refresh rate of the Normal mode are both in the normal state of the product, for example, 4K2K60Hz.

[0057] When the SOC module automatically detects that the input slice source format is 2K and the HSR switch in the system menu is turned on, the SOC module automatically starts the HSR technology, and the SOC module notifies the TCON module to turn on HSR through GPIO or IIC instruction.

[0058] For example, the SOC module sends a DATA signal (generally, a VBY1 signal) and a HSR identification signal at 4K1K 120Hz; the TCON module identifies the HSR signal and enters the HSR mode, and the GOA and P2P signals are displayed at 4K1K 120Hz.

[0059] When entering the HSR display mode, the SOC module identifies whether the input signal source state meets the FRC opening condition.

[0060] For example, if the input signal source refresh rate is 30Hz, and the current working state is HSR 120Hz, which meets the 4-frame FRC requirement, the system opens the FRC function, and the SOC module is changed from 4-frame repetition to 4-frame FRC to improve the color depth effect; if the input signal source refresh rate is 60Hz, and the current working state is HSR 240Hz, which meets the 4-frame FRC requirement, the system opens the FRC function, and the SOC module is changed from 4-frame repetition to 4-frame FRC to improve the color depth effect.

[0061] By using the above method, the display device of the embodiment can intelligently switch the display mode according to the user's demand and the system state when displaying a picture. In the default case, the display device plays the picture in the Normal mode to ensure that the user obtains a clear and stable visual experience. When the user needs a higher refresh rate to enjoy a smoother picture, the user only needs to open the HSR through the menu, and the display device can automatically enter the HSR identification mode, automatically identify the resolution, and realize high-resolution and high-refresh-rate picture display through the collaborative work of the SOC module and the TCON module.

[0062] In addition, the display device of the embodiment also has an intelligent FRC function. When the HSR mode is opened and the input signal source state meets the FRC opening condition, the display device will automatically open the FRC function, and the SOC module will process the picture through FRC, thereby further improving the color depth effect of the picture without sacrificing the resolution and refresh rate, so that the user can watch more delicate and rich colors.

[0063] In summary, the display device of the embodiment improves the refresh rate and resolution of the picture by using the HSR+FRC technology for display optimization, further enhances the color performance of the picture, and brings a better visual experience to the user.

[0064] Embodiment 3:

[0065] Based on the structure of Embodiment 1 and the method of Embodiment 2, as shown in Figure 3 The display device disclosed in the embodiment is based on the HSR+FRC technology and optimizes video display.

[0066] The display device realizes efficient processing of input video signals by integrating the SOC module and the TCON module, and using a self-developed SOC chip. The SOC module is responsible for receiving and analyzing video signals from different channels, such as HDMI, DTMB, LAN, or USB video sources, and intelligently identifying the resolution and refresh rate of the signals. When a low-resolution or low-refresh-rate video signal is identified, the SOC module can automatically enable the HSR technology to increase the refresh rate of the video signal to a preset high refresh rate state, such as HSR120Hz, thereby enhancing the smoothness of the picture.

[0067] In the HSR mode, the SOC module further judges whether the input signal source state meets the opening condition of the FRC function. When the condition is met, such as when the input signal source refresh rate is 30Hz and the system is working in the HSR mode 120Hz state, the SOC module will enable the FRC function, inserting transition frames between adjacent frames through an algorithm to enhance the color depth effect of the picture, making the color transition more natural and delicate. This FRC processing mode not only improves the problem of insufficient color levels of 8bit screens, but also brings users a visual experience close to 10bit color depth.

[0068] In addition, the display device also has flexible HSR identification signal transmission mode. When interacting with the TCON module, the SOC module can transmit HSR control instructions through the GPIO interface or the IIC bus. This dual-mode signal transmission mode improves the flexibility and stability of signal transmission, ensuring that the HSR technology can accurately and quickly respond to the instructions of the SOC module, thereby providing users with a smoother and clearer display experience.

[0069] With the above structure and method, the display device can achieve higher image refresh rate and richer color performance. The HSR technology converts the original low frame rate video signal into a high frame rate signal, making the picture more smooth and reducing the ghosting and blur phenomenon in dynamic images. The FRC technology further improves the depth and delicacy of color through frame rate conversion, making the picture color more vivid and realistic. Such an optimized combination not only improves the user's viewing experience, but also makes the display device take a new step in display technology.

[0070] The above is only the preferred specific implementation of the present application, but the protection scope of the present application is not limited thereto, any person skilled in the art can make equivalent replacement or change according to the technical solution and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
