Abstract

A display apparatus and a manufacturing method thereof which allow a component to be replaced and repaired simply, rapidly, and stably are provided. The display apparatus comprises a main body which accommodates a light source part, and comprises a display element which displays an image using light emitted from the light source part; an element panel which accommodates the display element; a front cover which is coupled to the main body and provided with a panel mounting part to which the element panel is detachably coupled; and an element driving board which is coupled to the front cover, is opposite to the main body, interposes the front cover between the element driving board and the main body, and is electrically connected with the display element.

Claims

1. A display apparatus comprising:

a light source part which emits light;

a main body which accommodates the light source part;

a display element which displays an image using the light emitted from the light source part;

an element panel which accommodates the display element;

a front cover which is coupled to the main body and is provided with a panel mounting part to which the element panel is detachably coupled; and

an element driving board which is coupled to the front cover, is opposite to the main body and is electrically connected with the display element, wherein the front cover is interposed between the element driving board and the main body,

wherein the display element comprises a digital micromirror device (DMD),

wherein the display element has a light incident side on which the light emitted from the light source part is incident and which faces a light incident direction,

wherein the following elements are provided in the following order in the light incident direction;

main body, front cover, and element driving board, and

wherein the display element is coupled to the front cover using a coupling which is different than a coupling which couples the element driving board to the front cover so that the element driving board can be removed from the front cover without removing the display element from the front cover.

2. The display apparatus according to claim 1, further comprising an interposer which supports the display element,

wherein the element panel comprises an element accommodating part which accommodates the interposer, and

the element accommodating part is provided with a pushing protrusion which pushes the interposer.

3. The display apparatus according to claim 1, further comprising a rear shield which is coupled to the element driving board to shield the element driving board.

4. The display apparatus according to claim 2, further comprising a rear shield which is coupled to the element driving board to shield the element driving board.

5. The display apparatus according to claim 1, wherein the panel mounting part and the element panel are formed with a panel coupling hole, and the front cover and the element panel are coupled together by a screw which is inserted through the panel coupling hole.

6. The display apparatus according to claim 1, wherein the image displayed by the display element is magnified and projected onto a screen.

7. The display apparatus according to claim 6,

wherein the front cover has a first side which faces the light incident direction and a second side which is opposite the first side, and

wherein the element driving board is provided on the second side of the front cover.

8. The display apparatus according to claim 7, wherein the element driving board is removable from the front cover without removing the front cover from the main body.

9. A method of manufacturing a display apparatus comprising a main body which accommodates a light source part, comprising:

coupling a display element to an element panel;

detachably coupling the element panel to a panel mounting part of a front cover;

coupling the front cover to the main body when the front cover is coupled with the element panel; and

coupling to the front cover an element driving board which is electrically connected with the display element, is opposite to the main body, and interposes the front cover between the element driving board and the main body,

wherein the display element comprises a digital micromirror device (DMD),

wherein the display element has a light incident side on which light, which is emitted by the light source part which is accommodated in the main body, is incident and which faces a light incident direction,

wherein the following elements are provided in the following order in the light incident direction once the display apparatus is manufactured;

main body, front cover, and element driving board, and

wherein the display element is coupled to the front cover using a coupling which is different than a coupling which couples the element driving board to the front cover so that the element driving board can be removed from the front cover without removing the display element from the front cover.

10. The method of manufacturing the display apparatus according to claim 9, further comprising:

accommodating the display element and an interposer which supports the display element to an element accommodating part which is formed to the element panel; and

pushing the interposer by a pushing protrusion which is formed to the element accommodating part.

11. The method of manufacturing the display apparatus according to claim 9, further comprising coupling a rear shield which shields the element driving board to the element driving board.

12. The method of manufacturing the display apparatus according to claim 10, further comprising coupling to the front cover an element driving board which is electrically connected with the display element, is opposite to the main body, and interposes the front cover between the element driving board and the main body.

13. The method of manufacturing the display apparatus according to claim 12, further comprising coupling a rear shield which shields the element driving board to the element driving board.

14. The method of manufacturing the display apparatus according to claim 9,

wherein the element driving device drives the display element,

wherein the front cover has a first side which faces the light incident direction and a second side which is opposite the first side, and

wherein the element driving board is coupled to the second side of the front cover.

15. The method of manufacturing the display apparatus according to claim 9,

wherein the display element forms an image using light which is emitted from the light source part which is accommodated in the main body, and

wherein the image formed by the display element is magnified and projected onto a screen.

16. A display apparatus comprising:

a main body in which a light source is provided;

a display element on which light emitted from the light source is incident and which forms an image using the light;

a front cover which is coupled to the main body and is detachably coupled to the display element; and

an element driving board which drives the display element, is coupled to the front cover, and is electrically connected with the display element,

wherein the image formed by the display element is magnified and projected onto a screen,
