Description

Touch panel {Touch panel}

The present invention relates to a touch panel, and more particularly, to a touch panel capable of improving visibility in a daytime when daylight is strong.

With the development of computers using digital technology, auxiliary devices of computers are being developed together. Personal computers, portable transmission devices, and other personal information processing devices use various input devices such as a keyboard and a mouse And performs text and graphics processing.

The technology related to the input device is shifting beyond the level that meets the general functions, such as high reliability, durability, innovation, design and processing related technology, etc. In order to achieve this purpose, input As a device, a touch panel has been developed.

Such a touch panel can be used as a flat panel display device such as an electronic notebook, a liquid crystal display device (LCD), a plasma display panel (PDP), and an electro luminescence (EL) And is a tool used by a user to select desired information while viewing the image display apparatus.

1 is a cross-sectional view schematically showing a configuration of a touch panel according to a conventional technique.

1, a conventional touch panel 10 includes a backlight unit 12, an LCD panel 14 for displaying an image, a polarizing plate 16 attached to the top of the LCD panel 14, a polarizing plate 16 And a unit touch panel 18 attached to an upper portion of the touch panel.

The light externally applied to the touch panel is diffused and scattered on the surface of the polarizing plate 16 and the unit touch panel 18, thereby deteriorating the visibility of the user.

In order to prevent such a problem, the anti-reflection film is attached to the surface of the unit touch panel 18, however, there is a problem in that visibility improvement is limited only by the anti-reflection film on the surface of the unit touch panel in the daytime when daylight is strong.

SUMMARY OF THE INVENTION The present invention has been conceived to solve the problems described above, and it is an object of the present invention to provide a polarizing plate including a touch panel, an anti-glare treatment unit touching the touch panel, Panel.

According to an aspect of the present invention, there is provided a touch panel including a backlight unit and an LCD panel for displaying an image, the touch panel comprising: a polarizer attached to an upper portion of the LCD panel and having a surface treated with anti-glare; A unit touch panel attached to an upper portion of the polarizer and having a surface treated with anti-glare; And an anti-reflection film attached on the unit touch panel.

The antireflection film may include a polyimide (PI) film.

The antireflection film may have a surface reflectance of 2% or less.

The present invention as described above has the effect of improving the visibility of the daytime in which daylight is strong due to anti-glare treatment of the polarizing plate and the unit touch panel included in the touch panel, and anti-

2 is a cross-sectional view schematically showing an example of the configuration of a touch panel according to the present invention.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

2 is a cross-sectional view schematically showing an example of the configuration of a touch panel according to the present invention.

2, the touch panel 100 includes a backlight unit 110, an LCD panel 120, a polarizer 130, a unit touch panel 140, and an anti-reflection film 150.

In the drawings, the components are shown as being placed apart from each other, but this is for easy understanding of the arrangement state of the components, and actually each component is stacked.

The backlight unit 110 emits a predetermined light for operation of the LCD panel 120 to be described later.

The LCD panel 120 can display a predetermined image required by the user.

Since the backlight unit 110 and the LCD panel 120 are well known in the art, detailed description thereof will be omitted.

A polarizer 130 is attached to the upper portion of the LCD panel 120.

The polarizer 130 may include a polyvinyl alcohol (PVA) polarizer and a polarizer protective film (not shown) laminated on one side of the polarizer.

Here, the polarizer 130 is subjected to anti-glare treatment to form an anti-glare layer 132 on the surface. The polarizer 130 may be attached on the LCD panel 120 by an adhesive.

The unit touch panel 140 senses the touch operation of the user and outputs a signal corresponding to the operation. At this time, since the unit touch panel 140 is made of a transparent material, the user can watch the image provided by the LCD panel 120 located at the lower part. The user can touch the predetermined position of the unit touch panel 140 and input necessary information when necessary.

The surface of the unit touch panel 140 is subjected to anti-glare treatment to form an anti-glare layer 142 on the surface.

An anti-reflection film 150 is laminated on the unit touch panel 140.

The antireflection film 150 prevents external light from being reflected from the surface. The antireflection film 150 used in the present invention preferably has a surface reflectance of 2% or less.

The antireflection film 150 can be manufactured by forming an antireflection layer 152 on the surface of a PI (Poly Imide) film by an antireflection treatment.

The anti-reflection layer 152 is formed on only one side of the anti-reflection film 150, but the anti-reflection layer 152 may be formed on both sides of the anti-reflection film 150.

The polarizing plate 130 and the unit touch panel 140 are respectively subjected to anti-glare processing and the anti-reflection film 150 is attached to the unit touch panel 140, Reflection and scattering of light irradiated onto the touch panel 100 can be reduced, and the visibility of the touch panel in the outdoors can be improved. In particular, the visibility of the touch panel in the outdoors where daylight is strong can be improved.

While the present invention has been described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims. Accordingly, the true scope of the present invention should be determined by the technical idea of the appended claims.
