[0034] like Figure 3 As shown, the display device includes a timing controller 100 and a display panel 200. The timing controller 100 can be used to drive the display panel 200 to display an image. In this embodiment, the timing controller 100 includes: an input module 110, a feature recognition module 120 connected to the input module 110, an image quality processing module 130 connected to the input module 110 and the feature recognition module 120, and an output module 140 connected to the image quality processing module 130.

[0035] Taking the timing controller 100 driving the display panel 200 to display the first screen as an example, the first screen can be any frame. The functions of each module in the timing controller 100 are as follows: the input module 110 is used to: acquire the first image data of the first screen; the feature recognition module 120 is used to: identify the screen features of the first screen according to the first image data; the image quality processing module 130 is used to: perform image quality optimization processing on the first image data according to the screen features to obtain the second image data of the first screen; the output module 140 is used to: drive the display panel 200 to display the first screen according to the second image data.

The input module 110 transmits the first image data to the feature recognition module 120, which analyzes the first frame based on the first image data to identify the features of the first frame. The feature recognition module 120 may be pre-configured with a trained feature recognition model, which can be an artificial intelligence model such as machine learning, deep learning, or reinforcement learning. The feature recognition module 120 can be implemented as, for example, a Neural Processing Unit (NPU). Through the feature recognition model, the feature recognition module 120 can intelligently analyze the first frame based on the first image data to automatically identify the features of the first frame.

[0037] This application does not limit the specific type of image features, and they can be flexibly set according to actual needs in practical applications. In some embodiments, image features may include, but are not limited to, at least one of the following: scene features, object features, and quality features.

[0038] Scene features are used to indicate the overall environment of the first screen. For example, scene features may include, but are not limited to, at least one of the following: application scenario (such as game, office, movie, screen projection, etc.), content scenario (such as portrait, landscape, animal, etc.), and environmental conditions (such as strong light, dark light, low light, warm light, cool light, etc.). It should be understood that the environmental conditions in the scene features refer to the features corresponding to the environment presented in the first screen, and not the features corresponding to the environment in which the display device is located.

[0039] Object features are used to indicate the main object in the first frame. For example, object features may include, but are not limited to, at least one of the following: human features (such as face, human shape, skin, hair, etc.), animal features (such as fur, tail, etc.), plant features (such as leaves, branches, flowers, etc.), scenery features (such as blue sky, white clouds, grassland, sea, mountain peaks, buildings, etc.), symbol features (such as titles, body text, subtitles, codes, tables, icons, etc.), product features (such as outlines, reflections, etc.).

[0040] Quality features are used to indicate the image quality of the first frame. For example, quality features may include, but are not limited to, at least one of the following: brightness distribution features (such as overexposed areas, underexposed areas, backlit silhouettes, brightness banding, etc.), color features (such as color block distortion areas, abnormal skin tone areas, saturation overflow, color banding, etc.), sharpness features (such as motion blur, film grain, loss of detail, etc.), temporal features (such as lens shake, moving targets, scene transitions, etc.).

[0041] The image quality processing module 130 receives first image data from the input module 110 and image features from the feature recognition module 120. It then performs image quality optimization processing on the first image data based on the image features to obtain second image data of the first image, which is then sent to the output module 140. This image quality optimization processing enhances the first image in multiple dimensions, including brightness, color gamut, and sharpness, thereby improving the display effect of the first image.

[0042] This application does not limit the specific methods of image quality optimization processing. In practical applications, the methods can be arbitrarily and flexibly set according to the needs and the specific types of image features. For example, image features include scene features. For example, for the scene feature of an office, image quality optimization processing may include blue light suppression processing, etc.; or, image features include object features. For example, for the object feature of a human face, image quality optimization processing may include local brightening, skin smoothing, eye sharpening, etc. For the object feature of a blue sky, image quality optimization processing may include sky color cast correction, saturation adjustment, etc.; or, image features include quality features. For the quality feature of motion blur, image quality optimization processing may include adaptive sharpening, etc.

[0043] The output module 140 drives the display panel 200 to display the first image based on the second image data output by the image quality processing module 130. Since the second image data has undergone image quality optimization processing, the display effect of the first image is improved. The output module 140 can drive the display panel 200 through a source drive circuit and a gate drive circuit. For example, the output module 140 can generate data signals and timing signals based on the second image data, and send the data signals to the source drive circuit so that the source drive circuit drives the display panel 200 according to the data signals, and send the timing signals to the gate drive circuit so that the gate drive circuit drives the display panel 200 according to the timing signals.

[0045] Taking the display panel 200 displaying the first image as an example, the output module 140 in the timing controller 100 is also used to: generate a data signal and a timing signal according to the first image data, and send the data signal to the source driving circuit 300 and the timing signal to the gate driving circuit 400; the source driving circuit 300 is used to: drive the display panel 200 according to the data signal; the gate driving circuit 400 is used to: drive the display panel 200 according to the timing signal.

[0047] The source drive circuit 300 and the display panel 200 can be connected via multiple data lines DL. The output module 140 in the timing controller 100 generates a data signal based on the second image data. The source drive circuit 300 can then drive multiple sub-pixels in the display panel 200 via the multiple data lines DL to adjust the brightness and / or color of the sub-pixels, thereby enabling the display panel 200 to display the first image. The source drive circuit 300 can be mounted on the display panel 200 or operate independently of it. Figure 4 Taking the source drive circuit 300 as an example, which is independent of the display panel 200, does not constitute a limitation of this application.

[0048] The gate driving circuit 400 and the display panel 200 can be connected via multiple gate lines GL. The output module 140 in the timing controller 100 generates a timing signal based on the second image data. The gate driving circuit 400 can then drive multiple sub-pixels in the display panel 200 via the multiple gate lines GL according to this timing signal, thereby controlling the on / off state of the sub-pixels and enabling the display panel 200 to display the first image. The gate driving circuit 400 can be mounted on the display panel 200 or independent of it. Figure 4 Taking the gate driving circuit 400 being disposed on the display panel 200 as an example, this does not constitute a limitation of this application.

[0049] like Figure 4As shown, the display device may also include a power management chip 500. The power management chip 500 can be connected to the timing controller 100, the source drive circuit 300, and the gate drive circuit 400, thereby providing power to the timing controller 100, the source drive circuit 300, and the gate drive circuit 400, and also providing the source drive circuit 300 with the gamma voltage required for its operation.

[0050] In summary, the technical solution provided in this application includes a timing controller comprising an input module, a feature recognition module, an image quality processing module, and an output module. The input module acquires first image data of a first frame; the feature recognition module identifies image features of the first frame from the first image data; the image quality processing module performs image quality optimization processing on the first image data based on the image features of the first frame to obtain second image data of the first frame; and the output module drives the display panel to display the first frame based on the second image data. By integrating the feature recognition module and the image quality processing module into the timing controller, this application can, on the one hand, detect image features in real time and perform targeted image quality optimization processing based on these features, achieving precise and intelligent optimization of the displayed image, dynamically adjusting image quality in real time, and improving the display effect of the display device; on the other hand, it eliminates the need for an additional image quality processing chip, integrating it into the timing controller, fully utilizing the processing power of the timing controller, reducing hardware costs, saving layout space, and contributing to the evolution of display devices towards narrow bezels, ultra-thin designs, and high integration.

[0051] Please see Figure 5 , Figure 5 This is a schematic diagram of another display device provided in an embodiment of this application. For example... Figure 5 As shown, in addition to the aforementioned input module 110, feature recognition module 120, image quality processing module 130, and output module 140, the timing controller 100 in the display device may also include an environment perception module 150 connected to the image quality processing module 130. The environment perception module 150 is used to acquire environmental data of the environment in which the display device is located; the image quality processing module 130 is also used to adjust the display parameters of the display device based on the environmental data.

[0052] By sensing environmental data in real time during the display process and adjusting the display parameters accordingly, the display device can adaptively adjust to external factors such as its environment, further optimizing the display effect. Furthermore, the environmental sensing module 150 and the image processing module 130 are integrated into the timing controller 100, fully utilizing the processing power of the timing controller 100, reducing external hardware requirements, and lowering system cost and power consumption.

[0053] This application does not limit the specific type of environmental data to be sensed in its embodiments, and can be flexibly set according to actual needs in practical applications. In some embodiments, environmental data may include, but is not limited to, at least one of the following: ambient brightness, ambient color temperature, ambient temperature, panel temperature, and user distance. Ambient brightness refers to the brightness of the environment in which the display device is located, such as low indoor light or strong outdoor light; ambient color temperature refers to the color temperature of the environment in which the display device is located, such as warm light or cool light; ambient temperature refers to the temperature of the environment in which the display device is located, while panel temperature refers to the operating temperature of the display panel 200 in the display device; user distance refers to the distance between the user viewing the screen and the display device, such as the distance between the human eye and the display panel 200. The above environmental data can be expressed as specific and precise numerical values ​​or as parameter levels. This application does not limit this; for example, ambient temperature can be expressed as 30°C or as high temperature.

[0054] This application does not limit the specific type of the adjusted display parameters in its embodiments. In practical applications, the parameters can be arbitrarily and flexibly set according to the specific needs and environmental data. In some embodiments, the display parameters may include, but are not limited to, at least one of the following: backlight data, color temperature data, and liquid crystal response time. Specifically, backlight data can be adjusted based on backlight brightness, backlight power, etc.; color temperature data can be adjusted based on a color temperature adjustment table (such as an Adaptive Color Compensation Table); and liquid crystal response time can be adjusted based on a liquid crystal response time table (such as an Overdrive Voltage Table).

[0055] For example, the environmental data includes ambient brightness, and the image quality processing module 130 can adjust the backlight brightness according to the ambient brightness, such as increasing the backlight brightness when the ambient brightness is high, to improve the picture quality; or, the environmental data includes ambient color temperature, and the image quality processing module 130 can adjust the color temperature adjustment table (such as the ACC table) of the display device according to the ambient color temperature to achieve dual white balance or correct color deviation and optimize the picture color; or, the environmental data includes ambient temperature and / or panel temperature, and the image quality processing module 130 can adjust the liquid crystal response time table (such as the OD table) of the display device according to the ambient temperature and / or panel temperature to prevent ghosting or overshoot, etc.

[0056] In some embodiments, such as Figure 5As shown, the display device may further include a data acquisition module 210 connected to the environment sensing module 150. The data acquisition module 210 is used to send raw environmental data to the environment sensing module 150; the environment sensing module 150 is also used to perform analog-to-digital conversion on the raw environmental data to obtain converted environmental data; the converted environmental data is used for image quality optimization processing.

[0057] By setting up a data acquisition module 210, which is responsible for the raw acquisition of environmental data, the position of the data acquisition module 210 can be flexibly set, thereby enriching the environmental data and improving its accuracy. Furthermore, since the data acquisition module 210 typically includes sensors, cameras, etc., the environmental data it acquires is usually an analog signal. The environmental perception module 150 can be implemented as an analog-to-digital converter (ADC). By performing analog-to-digital conversion on the environmental data through the environmental perception module 150, the environmental data is converted from analog signals to digital signals, which facilitates the subsequent analysis and processing by the image quality processing module 130.

[0058] This application embodiment does not limit the specific type and location of the data acquisition module 210; in practical applications, it can be flexibly configured according to requirements. In some embodiments, the data acquisition module 210 includes an embedded sensor in the display panel 200. That is, the data acquisition module 210 can be implemented as an embedded sensor (In-cell Sensor) and set in the display panel 200, thereby not only saving layout space but also enabling accurate acquisition of environmental data to effectively reflect the real-time status of the environment in which the display device is located. This application embodiment does not limit the number of embedded sensors included in the data acquisition module 210; in practical applications, it can be flexibly configured according to product design and requirements.

[0059] In some embodiments, such as Figure 5 As shown, the environment perception module 150 can also be connected to the feature recognition module 120. Therefore, the environment perception module 150 is further configured to: send environmental data to the feature recognition module 120; the feature recognition module 120 is further configured to: identify the screen features of the first image based on the first image data and the environmental data. By referring to the environmental data of the environment in which the display device is located when the feature recognition module 120 analyzes the first image, the accuracy and richness of the screen features identified by the feature recognition module 120 can be improved.

[0060] For example, the feature recognition module 120 is further configured to: recognize image features of the first image based on the first image data; associate the image features with environmental data; and send the image features associated with the environmental data to the image quality processing module 130. By associating the image features with the environmental data, the environmental data can be used as an additional label, thereby enabling the subsequent image quality processing module 130 to perform image quality optimization processing more accurately. For example, if the image features recognized by the feature recognition module 120 from the first image include text, and the environmental data perceived by the environmental perception module 150 includes low light, then the image features sent by the feature recognition module 120 to the image quality processing module 130 may include text in a low-light environment, and the image quality optimization processing performed by the image quality processing module 130 on the image features may include significantly increasing contrast, sharpening strokes, etc., to accurately improve image quality.

[0061] For example, the feature recognition module 120 is further configured to: adjust recognition parameters based on environmental data; and recognize image features of the first image based on the adjusted recognition parameters and the first image data. By adjusting the recognition parameters of the feature recognition module 120 based on environmental data, the feature recognition module 120 can extract more accurate image features. For example, the feature recognition module 120 can be implemented as a neural processing unit, including a feature recognition model. The recognition sensitivity and / or confidence threshold of the feature recognition model can be adjusted based on environmental data, such as increasing the recognition sensitivity of dark areas of the face when the ambient brightness is high, in order to accurately extract image features.
