Abstract

A display device embodiment can include a first module having an inverter component, a second module having a backlight component, a third module having a power supply, and where at least two of the first module, second module, and third module are replaceably connected together.

Claims

1. A display device, comprising;

a first module including a frame having a frame cover and a frame back that houses an inverter component and a liquid crystal display glass illuminator component;

a second module having a backlight component;

a third module having a power supply; and

where the second module and the third module are replaceably connected to an exterior of the first module.

2. The display device according to claim 1, where the second module and the third module are replaceably connected together.

3. The display device according to claim 1, where the replaceable connection between the first module and second module is provided by a releasable male connector and a releasable female connector being connected together and where the first module includes the male connector and the second module includes the female connector.

4. The display device according to claim 1, where the replaceable connection between the first module and second module is provided by a releasable male connector and a releasable female connector being connected together and where the first module includes the female connector and the second module includes the male connector.

5. The display device according to claim 1, where the display device includes a fourth module having a number of touch panel components and where the fourth module is at least electrically connected to the first module.

6. The display device according to claim 1, where the replaceable connection is an electrical connection.

7. The display device according to claim 1, where the replaceable connection is a physical connection.

8. The display device according to claim 1, where the device includes at least two modules replaceably connected electrically and at least two modules replaceably connected physically.

9. The display device according to claim 1, where at least one of the second module and the third module are removable from the exterior of the first module without disassembling the frame cover and the frame back.

10. A display device, comprising:

a first removable module including a frame housing a liquid crystal display glass illuminator component and an inverter component;

a second removable module having a backlight component;

a third removable module having a power supply, where at least two of the first module, second module, and third module are replaceably connected together; and

where the second module and the third module are replaceably connected to an exterior of the frame.

11. The display device according to claim 10, where the third module includes a video driver.

12. The display device according to claim 10, where the third module includes a filter heat sink.

13. The display device according to claim 10, where the third module includes a touch panel controller.

14. The display device according to claim 13, where the first and second modules are physically and electronically connected and where the third module is located remotely from the first and second modules and is electronically connected to at least one of the first and second modules.

15. The display device according to claim 14, where the first and second modules each have at least one ruggedized component and where the third module does not have a ruggedized component.

16. The display device according to claim 10, where the display device includes a first indicator connected to at least one of the modules to indicate that at least one of the connected modules has failed.

17. The display device according to claim 16, where the display device includes a first indicator connected to the first module to indicate that the first module has failed.

18. A display system, comprising;

a first module including a frame having a frame cover and a frame back that houses an inverter component and a liquid crystal display glass illuminator component;

a second module replaceably connected to an exterior of the frame and having a backlight component a third module replaceably connected to the exterior of the frame and having a power supply module and where at least two of the first module, second module, and third module are connected together; and

a first indicator electrically connected to at least one of the first and second modules to indicate that that the connected module has failed.

19. The system according to claim 18, where the first indicator is electrically connected to the first module to indicate that that the first module has failed and where the system includes a second indicator that is electrically connected to the second module to indicate that that the second module has failed.

20. The system according to claim 18, where the system includes a third indicator electrically connected to the third module to indicate that the third module has failed.

21. The system according to claim 19, where the system includes a third indicator electrically connected to the third module to indicate that the third module has failed.

22. The system according to claim 21, where the system includes a fourth indicator electrically connected to a fourth module to indicate that the fourth module has failed and where the fourth module includes a touch screen component.

23. A method, comprising:

providing a display device including;
