Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of display equipment, and in particular to a touch screen display device. Background Art
[0002] As the market position of smart phones and tablet computers continues to rise, the touch screen industry has been driven to become a sunrise industry. As more and more people like to use touch screen display devices to watch video movies, the traditional method is to add subtitles fixedly at the bottom center of the video screen. This method is simple and efficient. However, due to the richness and diversity of video content, subtitles may block the part of the video that the audience is interested in. And because there is usually continuity between video screens, this occlusion is often continuous, thus affecting the viewing experience. Based on various circumstances, people are in urgent need of a touch screen display device that can display subtitles of video content in a dynamic form, effectively avoid video content occlusion, and improve video playback effects and user viewing experience.
[0003] Therefore, it is necessary to design a touch screen display device that is practical and intelligent. Summary of the invention
[0004] The object of the present invention is to provide a touch screen display device to solve the problems raised in the above background technology.
[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: a touch screen display device, including a touch panel, a touch panel driving circuit, a central processing unit, an LED backlight driver, and an LED backlight, characterized in that: the touch display device also includes a color block recognition device, an eye tracking device and an AI recognition device, and the color block recognition device, the eye tracking device and the AI recognition device are all electrically connected to the central processing unit module, and are used for AI adjustment of subtitle position and color when the touch screen display device plays a video.
[0006] According to the above technical solution, the color block recognition device is connected to the LED backlight, and when it senses a large area of the same color of the LED backlight, it will recognize the color and quickly send a signal to the central processing unit module.
[0007] According to the above technical solution, the eye tracking device also includes an ultra-wide-angle front camera, an infrared light source, an image processor and a viewpoint computing core. The ultra-wide-angle front camera, infrared light source, image processor and viewpoint computing core are all arranged in sequence directly above the touch screen display device. Compared with ordinary lenses, the ultra-wide-angle lens has a shorter focal length and a larger field of view. Even if the user is very close to the screen, the facial information can still be collected and the human eye can be locked. The high-speed operation of the image processor and the viewpoint computing core can achieve high precision, low latency and a large field of view, so that users have a very good experience when watching videos.
[0008] According to the above technical solution, the ultra-wide-angle front camera collects facial images and captures the eye information of the user's head through the collection and tracking of infrared light sources, image processors and viewpoint calculation core components, and extracts the features of the captured image and obtains the position of the gaze point through precise calculation, and finally sends it to the central processing unit with the lowest delay.
[0009] According to the above technical solution, the ultra-wide-angle front camera can quickly and accurately capture the user's facial information and lock the position of the eyes. The image processor cooperates with the algorithm optimization at the software level and then transmits the signal to the LED backlight driver, so that the eye tracking device can sense the eye position and feed it back to the touch pad through the central processor.
[0010] According to the above technical solution, the central processing unit module still needs to receive the signals sensed by the color block recognition device and the eye tracking device to perform calculations when processing the operations of the original touch screen display device, and then combine with the AI recognition device to realize dynamic subtitles; users no longer have to worry about not being able to concentrate on watching the plot pictures while watching subtitles. This solution allows the subtitles to be presented according to the position of the user's eyes.
[0011] The central processing unit module can combine the signals sent by the color block recognition device and the eye tracking device at the same time, so that the subtitles can be displayed in a large area of color blocks and can also be displayed at a suitable position near the eye focus point according to the movement of the user's eyeballs when watching the plot. The specific selection process is as follows:
[0012] When the eye focus and the color block tracked by the eye tracking device are not in the same place, the central processing unit will give priority to processing the signal of the eye tracking device to intelligently identify the position where the eyes are locked on the screen, and then use this position as the center point to find the large area color block identified by the color block recognition device at the place closest to the center point to present the subtitles. The color of the color block identified by the color block recognition device is uploaded to the central processing unit, and the central processing unit will intelligently change the color of the subtitles according to the color block color, and transmit the signal to the LED backlight driver, thereby achieving a high contrast between the subtitles and the color of the color block behind the subtitles; combined with the position of the eye focus and the large area color block, the subtitles appearing on the screen can follow the position of the eye and avoid unnecessary occlusion. The more humanized design changes the color of the subtitles as the color block behind the subtitles changes, forming a strong contrast with the picture, and successfully solves the embarrassment of traditional subtitles and background colors being the same and unclear.
[0013] According to the above technical solution, the artificial intelligence recognition function of the AI recognition device can recognize shots of character dialogues. When there are shots of character dialogues in the plot, the AI will recognize the dialogue signals based on the up and down jumping and closing of the characters' lips, and then the central processor will transmit the signals to the LED backlight driver according to the set mode to present personalized subtitles such as bubble subtitles on the screen.
[0014] According to the above technical solution, the AI recognition device divides the length and width of the screen into four equal parts, and the entire screen is divided into sixteen small rectangular grids. At this time, the AI recognition device will intelligently identify and distinguish the scene lens mode signal according to the size of the characters or main objects in the plot:
[0015] a. When a person or thing occupies more than 12 blocks on the screen, AI recognition will determine that it is a close-up shot;
[0016] b. When a person or thing occupies six to twelve squares on the screen, AI recognition will determine that this is a close-up shot;
[0017] c. When the image of an individual person or object occupies less than six squares on the screen, AI recognition will determine that this is a long shot.
[0018] According to the above technical solution, the AI recognition device will transmit the recognized different lens modes to the central processor and then connect to the LED backlight driver and the LED backlight to output corresponding personalized subtitles. The specific presentation method is:
[0019] a. When AI recognizes that this is a close-up shot, since the main image occupies a large proportion of the screen, the subtitles will be directly presented in the large color block area in the main image according to the focus position locked by the eyeball; with the color block area signal feedback from the color block recognition device, the subtitles can be evenly arranged in the large color block area;
[0020] b. When AI recognizes that this is a close-up shot, the main content generally occupies a moderate proportion of the screen, and the subtitles will be presented at the closest position to the screen focus outside the main character or object based on the focus position of the eyeball;
[0021] c. When AI recognizes that this is a long shot, the main content usually occupies a smaller proportion of the screen, and a large amount of blank area will be left on the screen. Generally, users will watch the entire video content. At this time, subtitles will appear outside the main object and in a large color block in the central area of the eye focus.
[0022] Compared with the prior art, the beneficial effects achieved by the present invention are:
[0023] (1) By providing an eye tracking device, when the user watches the video on the touch screen display device, the eye tracking device will quickly lock the user's eye information and make corresponding feedback, and the subtitles will always appear flexibly where the user's naked eyes see;
[0024] (2) A color block recognition device is provided to sense the large color block area and the color of the color block on the screen, and then transmit it to the LED light through the central processing unit, so as to present high-contrast subtitles in the large color block area as much as possible;
[0025] (3) An AI recognition device is provided to be able to recognize different lens images such as dialogue shots, close-up shots, and long shots, and make corresponding subtitle mode switches. BRIEF DESCRIPTION OF THE DRAWINGS
