Problems solved by technology

[0006] However, in the increasingly thin margins of electronic products and the increasingly fierce price competition, the adoption of the above-mentioned method not only increases the production cost of display devices, but also stifles the profit space of manufacturers.
In addition, it is not a wise choice to make the display device compatible with two aspect ratio playback formats by changing the architecture of the driving integrated circuit, which also increases the difficulty of designing the display device.

Embodiment Construction

[0045] For the convenience of description, the following embodiments will assume that the resolution of the original image data is 1280×900, and also assume that the resolution of the display panel in the display device (taking a liquid crystal display as an example) is 1280×1024. In addition, the following embodiments will illustrate the operation mode of the present invention by taking the centering of the screen displayed on the display panel as an example. In the following embodiments, FIG. 3 is a circuit diagram of a display device according to the present invention. 4, 5, 6, 7, and 8 are flowcharts of the screen display method according to the present invention. 9 and 10 are signal timing diagrams of the image display method according to the present invention. Please refer to the above figures according to the needs of the description.

[0046]301, 302, 303, 304, and 305 in FIG. 3 are a processing unit, a timing controller (Timing Controller), a source driver (Source Driver)...

Abstract

A frame display method and display device fits for displaying several frame data on screen in video signal. And every two adjacent frame data in video signal has a vertical interregnum. The display method includes several steps. It displays the background picture on screen between the interregnums. And it displays said picture data on the screen between the non-interregnums.

Description

Technical field [0001] The present invention relates to a display device and a screen display method thereof, and more particularly to a display device and a screen display method capable of displaying screens with different panel resolutions on a panel. Background technique [0002] Relevant studies have shown that the natural field of view ratio of the human eye is 16:9, which means that the optimal ratio of the "golden section" of the image captured by the human eye is 16:9. When the horizontal viewing angle range of observing a scene is close to 28°~30°, the eyes do not need to forcibly adjust the visual focus point on the scene image, and the image will naturally fill the entire field of view. When viewing a 16:9 aspect ratio (also known as the aspect ratio), the visual range is about 27°, which is close to the natural focusing angle of view. When viewing a 4:3 aspect ratio at the same distance, the eyes are forced to feel tired because the horizontal viewing angle is only 1...
