A high-resolution OLED device comprises pixel units which are distributed into matrixes, each pixel unit comprises four pixels, and each pixel comprises a red sub-pixel, a green sub-pixel and a blue sub-pixel; each red sub-pixel, the corresponding green sub-pixel and the corresponding blue sub-pixel are distributed in a shape like a Chinese character 'pin' in the corresponding pixel, and the red sub-pixels, the green sub-pixels and the blue sub-pixels of every two adjacent pixels in each pixel unit are symmetrical with respect to the public edge of the corresponding pixels. The high-resolution OLED device has the advantages that a manufacturing method is based on the proven FMM technique in the industry, but according to the special pixel distribution mode, a MASK evaporated with organic light-emitting materials is in a mesh shape, and each open hole corresponds to four sub-pixels. Under the situation of the same resolution, sizes of the open holes and sizes of connection bridges of the MASK are larger. A high-resolution OLED display screen can be manufactured on the basis the proven FMM technique in the industry; alternatively under the situation of the same resolution, the requirement for MASK processing and OLED display screen manufacturing processes can be reduced, and improvement on the product yield is facilitated.

The invention discloses a stereoscopic display, which comprises a liquid crystal display (LCD), a backlight polaroid, a light-emitting diode (LED) backlight source A, an LED backlight source B and a control unit. A display control method comprises the following steps of: alternatively displaying pictures shot by a stereoscopic camera from left eye pictures to right eye pictures through the LCD; and controlling the LED backlight source A and the LED backlight source B to emit light in the left eye pictures and the right eye pictures, wherein light rays emitted by the LED backlight source A andthe LED backlight source B pass through linear polaroid elements with mutually vertical polarization directions in the backlight polaroid; formed polarized light passes through the LCD; an observer can alternatively see the left eye pictures and the right eye pictures shot by the stereoscopic camera with a left eye and a right eye by wearing linear polaroid eyeglasses with mutually vertical polarization directions on the left eye and the right eye; and a stereoscopic image can be seen by brain processing of a human body. The stereoscopic display is easy to realize, has high stereoscopic impression and high picture quality, makes watching comfortable and can be applied to occasions such as televisions, computer displays, digital photo frames and the like.

The present invention discloses a backlight module, which comprises a light guide plate and a light bar disposed on the light guide plate, wherein white light sources and monochromatic light sources having at least one color of N primitive colors wherein N is greater than or equal to 3. The present invention further discloses a display device comprising such a backlight module. With the present invention, the color gamut range of a light-emitting diode (LED) backlight display system can be widened.

An interior-adhering transparent film and preparation method therefor, comprising a transparent film body. The transparent film body includes a self-adhesive, ink-absorbing, transparent plastic soft film and a shape-fixing transparent plastic film that prevents the self-adhesive, ink-absorbing, transparent plastic soft film from deforming caused by stretching. Provided between the shape-fixing transparent plastic film and the self-adhesive, ink-absorbing, transparent plastic soft film is a color-rendering print layer. Distributed on the color-rendering print layer are transparent areas. On the self-adhesive, ink-absorbing, transparent plastic soft film, the side facing away the color-rendering print layer and the surface of the transparent areas is the side that absorbs print ink and adheres. The present invention enables users to conveniently jet draw and adhere pictures, and also ensures that the pictures do not peel off due to contraction and deformation. The color-rendering print layer and the transparent areas ensure picture display clarity, light transmission, and transparency. As the self-adhesive, ink-absorbing, transparent plastic soft film absorbs ink and is colored even at the transparent areas, the pictures jet drawn are complete and uninterrupted, thereby providing high clarity for the pictures, and enabling the picture being displayed on the reverse side.

An image processing method, system, device and medium provided by the present invention, aiming at the current problems, designs an image processing method, which can distinguish high-definition images and low-definition images from real images; and also designs a The degradation model can first learn the characteristics of the low-definition image, and generate a simulated low-definition image corresponding to the high-definition image one by one, which solves the problem that the super-resolution model is difficult to train on the real image; at the same time, the present invention also designs a filter mechanism, Splitting the image into high-frequency and low-frequency parts significantly improves the super-resolution effect of real images. Moreover, the present invention has versatility, and according to different application scenarios, the optimal super-resolution effect of the scenario can be obtained only by using corresponding real images for training. Moreover, the image after the image quality is improved by the super-resolution model in the present invention has no distortion in color, clear details, sharp edges, and a good overall look and feel.

The invention discloses a method and device for color synthesis in high dynamic range image synthesis. The method includes: respectively determining the first and second color values ​​according to the value distribution of the brightness values ​​of pixels in the target LE image and the target HE image. A color difference adjustment function; adjust the color difference values ​​of the target LE image and the target HE image respectively according to the first and second color difference adjustment functions, and use the adjusted color difference value to synthesize the intermediate color difference value of the middle high dynamic range image; obtain the target The composite brightness value of the high dynamic range image; according to the brightness value of the pixel point in the target LE image and the target HE image, the composite brightness value of the target high dynamic range image, and the first and second color difference adjustment functions, determine the saturation adjustment factor; adopt The saturation adjustment factor adjusts the intermediate color difference values ​​of the intermediate high dynamic range image to generate the composite color difference value of the target high dynamic range image. With this color synthesis method, no color distortion will occur.
