摘要： A method for processing image data with reduced transmission bandwidth is provided. The method includes receiving a first set of data for image in a first resolution and receiving a center coordinate. The method further includes determining a high-definition region including an area and a boundary centered on the center coordinate. Additionally, the method includes rendering the first set of data based on the center coordinate and the area of the high-definition region to obtain a first subset of data. Furthermore, the method includes rendering a set of data compressed from the first set of data to obtain a second subset of data beyond the boundary. Moreover, the method includes transmitting a second set of image data to the display panel combining the first subset of data for display image in the first resolution and the second subset of data to display image in the second resolution.

摘要： The invention discloses a light-emitting unit, comprising a backplane and a light source provided on the backplane. The light source includes a plurality of sub light sources. The light-emitting unit further comprises light reflecting structures provided between the sub light sources. The light reflecting structures are configured to reflect the light radiating thereon from the sub light sources into the light-emitting direction of the light-emitting unit. Accordingly, the invention discloses a backlight module including the light-emitting unit and a display device including the backlight module. The backlight module in the invention is not only capable of improving a Hotspot phenomenon, but also capable of preventing the light source in the light-emitting unit from directly contacting with a light guide plate.

摘要： The general inventive concepts provide a side-light type backlight unit. The side-light type backlight unit comprises a light guide plate and a light source located at the side of the light incident surface of the light guide plate. The light source comprises a circuit board which comprises a first region opposite to the light incident surface of the light guide plate and a second region adjacent to the first region. The first region and the second region are provided with LED lamps. By arranging LED lamps in both the first region and the second region of the circuit board of the side-light type backlight unit, the incident light of the side-light type backlight unit is increased, thereby improving the luminance of the side-light type backlight unit in 3D state. The disclosure further provides a display device comprising such a side-light type backlight unit.
