Abstract

A display unit includes a substrate supporting section having: a first supporting structure for supporting a first circuit substrate; and a second supporting structure for supporting a second circuit substrate is provided. The first circuit substrate has a relatively small area and is selected when a first display panel having a single light source for emitting backlight is selected, and the second circuit substrate has a relatively large area and is selected when a second display panel having two light sources for emitting backlight is selected. The first supporting structure has a supporting claw for supporting the first circuit substrate such that the front side of the first circuit substrate is directed upward and the second supporting structure has a stand on which the second circuit substrate is mounted to be supported thereby such that the front side of the second circuit substrate is directed downward.

Claims

1. An electronic apparatus comprising:

a display panel having a display screen for displaying information and a light source for lighting the display screen;

a circuit substrate mounted with a light control circuit for controlling lighting of the light source; and

an enclosure that has a substrate supporting section for supporting the circuit substrate, and houses and covers the circuit substrate, the enclosure housing the display panel such that a front surface of the display screen is exposed,

wherein the display panel is a panel selected from among plural display panels having different numbers of light sources,

the circuit substrate is either a first circuit substrate with a relatively small area to be selected when a first display panel is selected from among the plural display panels or a second circuit substrate with a relatively large area to be selected when a second display panel is selected from among the plural display panels, and

the substrate supporting section has a first supporting structure for supporting the first circuit substrate and a second supporting structure for supporting the second circuit substrate.

2. The electronic apparatus according to claim 1, wherein the circuit substrate has a front side where circuit components composing the light control circuit are mounted,

the first supporting structure has a supporting claw for supporting the first circuit substrate such that a front side of the first circuit substrate and the front surface of the display screen face in the same direction, and

the second supporting structure has a stand on which the second circuit substrate is mounted such that a front side of the second circuit substrate and the front surface of the display screen face in opposite directions.

3. The electronic apparatus according to claim 1, wherein the enclosure has a back plate with an area larger than the display panel for housing the display panel and a front frame for covering a periphery of the display panel from the front surface side of the display screen, and

the substrate supporting section is disposed at such a position of the back plate that the substrate supporting section avoids overlapping the display panel.

4. The electronic apparatus according to claim 1, further comprising a second enclosure coupled to the enclosure in an openable and closable manner.

5. The electronic apparatus according to claim 4, wherein the second enclosure is an enclosure that forms a data-processing unit provided with a keyboard disposed on a top surface thereof to input an instruction according to an operation.

6. A display panel enclosure that houses a display panel having a display screen for displaying information and a light source for lighting the display screen, wherein:

the display panel is a panel selected from among plural display panels having different numbers of light sources,

the display panel enclosure comprises a circuit substrate mounted with a light control circuit for controlling lighting of the light source, the circuit substrate being either a first circuit substrate with a relatively small area to be selected when a first display panel is selected from among the plural display panels or a second circuit substrate with a relatively large area to be selected when a second display panel is selected from among the plural display panels, and

the display panel enclosure further comprises a substrate supporting section that includes a first supporting structure for supporting the first circuit substrate and a second supporting structure for supporting the second circuit substrate.

7. The display panel enclosure according to claim 6, wherein the circuit substrate has a front side where circuit components composing the light control circuit are mounted,

the first supporting structure has a supporting claw for supporting the first circuit substrate such that a front side of the first circuit substrate and the front surface of the display screen face in the same direction, and

the second supporting structure has a stand on which the second circuit substrate is mounted such that a front side of the second circuit substrate and the front surface of the display screen face in opposite directions.

8. The display panel enclosure according to claim 6, further comprising a back plate with an area larger than the display panel for housing the display panel and a front frame for covering a periphery of the display panel from the front surface side of the display screen,

wherein the substrate supporting section is disposed at such a position of the back plate that the substrate supporting section avoids overlapping the display panel.
