Abstract

To provide a rigid digitizer-integrated display module, the display module includes a display panel for forming an image, a digitizer module formed on the bottom side of the display panel to detect electromagnetic type digitizer input, and a non-magnetic metal structure enclosing the bottom sides of the mold frame and the digitizer and the outer periphery of the mold frame.

First claim

What is claimed is:

1. A display device comprising:
a display panel for forming an image;
a digitizer module formed below the display panel to detect electromagnetic type digitizer input;
a magnetic metal structure enclosing sides of the display panel and entirety of sides and a bottom side of the digitizer module; and
a non-magnetic metal structure enclosing a periphery and a bottom side of the magnetic metal structure.

2. The display device as claimed in claim 1 , further comprising a touch panel formed on a top of the display panel.

3. The display device as claimed in claim 1 , wherein the display panel comprises:
a liquid crystal panel for forming an image; and
a backlight panel positioned under the liquid crystal panel to illuminate light to the rear side of the liquid crystal panel.

4. The display device as claimed in claim 1 , wherein the display panel comprises:
a substrate formed on the digitizer module;
a bottom electrode formed on the substrate;
an organic layer formed on the bottom electrode; and
a top electrode formed on the organic layer.

5. The display device as claimed in claim 1 , wherein the digitizer module comprises:
an Electro Magnetic Resonance (EMR) sensor substrate positioned on the bottom side of the display panel and having a plurality of loop coils arranged on the EMR sensor substrate to detect an electromagnetic field produced by a pen for an electromagnetic type digitizer.

6. The display device as claimed in claim 1 , wherein the non-magnetic metal structure is formed from one of aluminum, magnesium and non-magnetic SUS (Steel Use Stainless).

7. The display device as claimed in claim 1 , wherein the magnetic metal structure is formed from a silicon-based iron.

8. The display device as claimed in claim 1 , further comprising:
a mold frame enclosing the sides of the display panel and the digitizer module, the mold frame being opened vertically, wherein the magnetic metal structure encloses a bottom side of the mold frame and the digitizer module, and sides of the mold frame.
