Display module
A display module, used for, e.g., a plasma display panel, is disclosed. In one embodiment, the display module includes a display panel, a drive circuit board driving the display panel, and a chassis base supporting the display panel and the drive circuit board. A curved portion is formed on the chassis base with a predetermined width, a boss is installed on an upper surface of the curved portion, and the drive circuit board is installed on the top of the boss. According to embodiments of the present invention, the strength of the chassis base constituting the display module is reinforced, without requiring a separate reinforcement member, and simultaneously the heat and noise generated by the display panel and the drive circuit board during operation can be appropriately dissipated and prevented.

a boss provided on an upper surface of the curved portion, wherein the drive circuit board is provided on the top of the boss.
2. The display module as claimed in claim 1 , further comprising:
a heat dissipation sheet having a predetermined size smaller than the display panel and a double-sided adhesive tape disposed between the display panel and the chassis base; and
a sound absorption member provided in a space defined by the curved portion and at least one of the heat dissipation sheet and the display panel.
3. The display module as claimed in claim 1 , further comprising:
a heat dissipation sheet and a double-sided adhesive tape disposed between the display panel and the chassis base; and
a heat transfer medium provided in a space defined between the curved portion and at least one of the heat dissipation sheet and the display panel.
4. The display module as claimed in claim 1 , further comprising:
a heat dissipation sheet and a double-sided adhesive tape disposed between the display panel and the chassis base; and
a noise reduction member and a heat transfer medium provided in a space formed between the curved portion and at least one of the heat dissipation sheet and the display panel.
5. The display module as claimed in claim 3 , wherein the heat transfer medium is formed of one of the following: graphite, silicon, acryl, and urethane which exhibit superior heat conductivity.
6. The display module as claimed in claim 2 , wherein the sound absorption material is formed of one of the following: expanded polystyrene, sponge, and asbestos which are porous materials.
7. The display module as claimed in claim 1 , wherein the display module is for use with a plasma display panel.
8. The display module as claimed in claim 1 , wherein the curved portion is formed in a latitudinal direction of the display panel.
9. A plasma display apparatus, comprising:
a chassis base configured to support a display panel and a drive circuit board, wherein the chassis base comprises first and second flat portions and a curved portion, wherein the curved portion is interposed between and continuous from the flat portions, wherein the curved portion comprises i) a first sub-portion bent outwardly from the first flat portion, ii) a second sub-portion extending from the first sub-portion in substantially parallel to the flat portions and iii) a third sub-portion extending from the second sub-portion and bent inwardly toward the second flat portion, and wherein the lengths of the first and third sub-portions is substantially less than that of the second sub-portion; and
a connecting member configured to connect the drive circuit board to the curved section of the chassis base.
10. The plasma display apparatus as claimed in claim 9 , further comprising:
a heat dissipation sheet located between the display panel and the chassis base; and
at least one of a noise reduction member and a heat transfer medium provided in a space defined by the curved portion and the heat dissipation sheet.
11. A plasma display apparatus, comprising:
a chassis base configured to support a display panel and a drive circuit board, wherein the chassis base comprises first and second flat portions and a curved portion, wherein the curved portion is interposed between and continuous from the flat portions, wherein the curved portion comprises i) a first sub-portion bent outwardly from the first flat section, ii) a second sub-portion extending from the first sub-portion in substantially parallel to the flat portions and iii) a third sub-portion extending from the second sub-portion and bent inwardly toward the second flat portion, and wherein the lengths of the first and third sub-portions is substantially less than that of the second sub-portion; and
a connecting member configured to connect the drive circuit board to the curved portion of the chassis base,
wherein the chassis base does not require a separate reinforcement member.
