Description

Display device {DISPLAY DEVICE}

The present invention relates to a display device, and more particularly, to drastically omit some of the case or / and set cover configurations, which were considered essential components of the display product, to reduce the thickness and improve the front aesthetic of the display product. To one display device.

Recently, various flat panel display devices have been developed to reduce weight and volume, which are disadvantages of cathode ray tubes. The liquid crystal display device, the plasma display panel, the field emission display device, and the light emitting display device are actively researched as the flat display device. However, liquid crystal display devices have been in the spotlight due to mass production technology, ease of driving means, and high quality.

In recent years, the necessity of R & D in the design aspect of products that can appeal more to the users in addition to the R & D of the technical aspects of flat panel display devices has been particularly highlighted. Accordingly, efforts are being made to minimize (slim) the thickness of the display device, and the demand for designs with enhanced aesthetics that can stimulate purchases by appealing to the aesthetic sense of the consumer is gradually increasing.

However, the design development for slimming or enhancing the aesthetics of the display device, which has been carried out to date, has been progressed in such a manner that the structure of the component is changed while adopting the components constituting the conventional display device. There are some limitations in slimming down and developing new designs.

For example, in the case of a liquid crystal display device, in order to accommodate a display panel and a back light unit, a lower case and an upper case are essentially used, and also commercialized as a notebook, a monitor, a mobile device or a television. Separate front and rear set covers were additionally used for this purpose. As such, since the lower case and the upper case and the front and rear set covers of the product are essentially used, there is a limit in reducing the product thickness or changing the design of the liquid crystal display. In particular, since the upper case and the front set cover essentially cover the front edge of the display panel, the thickness of the liquid crystal display is inevitably increased, and the border width of the liquid crystal display is increased and the step of the edge portion is increased. There is a problem that the front aesthetics of the display product is lowered.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems, so as to drastically omit some of the case or / and set cover configurations, which were considered essential components of the display product, to reduce the thickness and improve the front aesthetic of the display product.

1 is a cross-sectional view schematically illustrating a display device according to a first embodiment of the present invention.

Referring to FIG. 1, the display apparatus 100 according to the first exemplary embodiment may include a set cover 110, a backlight unit 120, a guide frame 130, a display panel 140, and an edge member ( 150).

The set cover 110 may be formed in a rectangular plate shape, and may be made of a plastic material or a metal material. However, the set cover 110 may be made of a metal material to improve aesthetics of a commercialized display device. The set cover 110 serves as a back cover of a commercialized display device (eg, notebook, monitor, or television).

The backlight unit 120 includes a light guide plate 122, a reflective sheet 124, and an optical member 126.

The light guide plate 122 is formed in the shape of a flat plate to have a light incident surface to propagate light incident from the light source (not shown) onto the light incident surface toward the display panel 140. Here, the light source may include a substrate and a plurality of light emitting diodes mounted on the substrate, but is not limited thereto, and may include a fluorescent lamp.

The reflective sheet 124 is mounted on the set cover 110 to be disposed on the rear surface of the light guide plate 122 to reflect the light incident from the light guide plate 122 toward the light guide plate 122.

The optical member 126 is disposed on the light guide plate 122 to improve luminance characteristics of light traveling from the light guide plate 122 toward the display panel 140. To this end, the optical member 126 may include a lower diffusion sheet, at least one prism sheet, and an upper diffusion sheet.

The guide frame 130 is coupled to the set cover 110 to wrap the backlight unit 120 and to support the display panel 140. To this end, the guide frame 130 is configured to include a guide side wall and the panel seating portion.

The guide side wall is vertically formed to surround the side of the backlight unit 120. At this time, the guide side wall is installed on the set cover 110 by an adhesive member (eg, double-sided tape or adhesive) (not shown) or on the set cover 110 by the first fastening member 112. Here, the first fastening member 112 may be a screw fastened to the guide sidewall through the set cover 110.

The panel seating portion is bent to have a predetermined length from the top surface of the guide sidewall to support the rear edge portion of the display panel 140.

The display panel 140 is mounted on the panel mounting portion of the guide panel 130 to display a predetermined image according to the transmittance of light emitted from the backlight unit 120. To this end, the display panel 140 includes a lower substrate 142, an upper substrate 144, a lower polarizer 146, and an upper polarizer 148.

Each pixel may include a thin film transistor (not shown) connected to a gate line and a data line, a pixel electrode connected to a thin film transistor, and a common electrode formed to be adjacent to the pixel electrode and supplied with a common voltage. The lower substrate 142 adjusts the light transmittance of the liquid crystal layer by forming an electric field corresponding to the difference voltage between the data voltage and the common voltage applied to each pixel.

The upper substrate 144 is configured to include a color filter corresponding to each pixel formed on the lower substrate 142 so as to oppose the lower substrate 142 with the liquid crystal layer interposed therebetween. In this case, the common electrode to which the common voltage is supplied may be formed in the upper substrate 144 according to the driving method of the liquid crystal layer. The upper substrate 144 filters a light incident through the liquid crystal layer with a color filter to emit predetermined color light to the outside so that a predetermined color image is displayed on the display panel 140.

Meanwhile, specific configurations of the lower substrate 142 and the upper substrate 144 may include a driving mode of the display panel 140, for example, a twisted nematic (TN) mode, a vertical alignment (VA) mode, and an in plane switching (IPS) mode. Depending on the mode, the FFS (Fringe field switching) mode, etc., it may be formed in various forms known in the art.

The lower polarizer 146 is formed on the rear surface of the lower substrate 142 to polarize the incident light and irradiate the lower substrate 142.
