Abstract

An information handling system provides connectors along a housing periphery with a reduced vertical footprint by adjusting a display circuit portion relative to a display panel portion to provide vertical space for the connectors. For example, the circuit portion aligns with the display panel portion along one side of the display to provide space for connectors at that side of the display, and the circuit portion extends past the perimeter of the display panel portion at an opposing side of the display. In one embodiment, the circuit portion extending outside the perimeter of the display panel portion includes circuits for powering a backlight disposed in the circuit portion.

Claims

1. An information handling system comprising:

a housing having a perimeter;

a processor disposed in the housing and operable to process information;

memory disposed in the housing and interfaced with the processor, the memory operable to store the information; and

a display disposed in the housing and interfaced with the processor, the display operable to present the information as visual images, the display having a display panel portion and a circuit portion interfaced with the display panel portion, the circuit portion including circuits to support presentation of visual images at the display panel portion;

wherein the display panel portion couples offset with the circuit portion to have at least some of the circuit portion extending past a first side of the display panel portion, the circuit portion disposed substantially in alignment with a second side of the display panel portion opposite the first side.

2. The information handling system of claim 1 wherein:

the display panel portion comprises a liquid crystal display panel operable to create the visual images; and

the circuit portion comprises one or more backlights operable to generate light that passes through the display panel portion to present the visual images.

3. The information handling system of claim 2 wherein the circuit portion extending past the first side of the display panel portion comprises power circuits for powering the one or more backlights.

4. The information handling system of claim 1 further comprising one or more peripheral ports disposed at the second side adjacent the display panel portion and circuit portion and exposed at the housing perimeter for accepting peripheral cables.

5. The information handling system of claim 1 wherein the display panel is symmetrically disposed in the housing and the circuit portion is non-symmetrically disposed in the housing.

6. A method for manufacture of an information handling system, the method comprising:

assembling a display by coupling a circuit portion and display panel portion to each other to align at a first side, the circuit portion extending past the display panel portion at a second side opposite the first side;

coupling the display to a housing having a perimeter, the circuit portion at the second side adjacent the housing perimeter; and

coupling one or more peripheral ports to the housing adjacent the display at a one end and the housing perimeter at an opposing end.

7. The method of claim 6 wherein the circuit portion comprises a backlight operable to provide illumination to the display panel.

8. The method of claim 7 wherein the coupling the display to a housing further comprises aligning the display panel portion symmetrically in the housing, the circuit portion having a non-symmetrical alignment relative to the housing.

9. The method of claim 7 further comprising coupling a bezel to the housing perimeter to cover the peripheral ports.

10. The method of claim 7 wherein the peripheral ports comprise USB ports.

11. A display comprising:

a display panel having plural pixels, the pixels generating visual images by altering light that passes through the pixels, the display panel having four sides that form a perimeter;

a circuit portion coupled to the display panel, the circuit portion having one or more backlights to provide light that passes through the display panel;

wherein the circuit portion extends past at least one side of the display panel and outside of the perimeter, and the circuit portion remains within the perimeter along at least one of the other sides of the display panel.

12. The display of claim 11 wherein the circuit portion comprises plural LED backlights that provide illumination to pass through the pixels.

13. The display of claim 12 wherein the circuit portion that extends past at least one side of the display panel comprises power circuits to provide power to the plural LED backlights.

14. The display of claim 11 further comprising one or more external device connectors disposed adjacent the circuit portion that remains within the perimeter.

15. The display of claim 14 wherein the device connectors comprise USB ports.

16. A method for assembly of a tablet information handling system, the method comprising:

coupling a connector to a housing at a perimeter of the housing, the connector having an exposed end accessible through an opening of the housing for coupling with a cable;

coupling a display to the housing adjacent to the connector at an overlapping vertical height with the connector, the display having a display portion and a circuit portion, the circuit portion extending outside a perimeter of the display portion in a location distal the connector; and

covering the perimeter of the display with a housing upper portion coupled over the housing.

17. The method of claim 16 wherein the covering the perimeter further comprises exposing the display portion symmetrically centered in the housing.

18. The method of claim 16 wherein the circuit portion comprises a backlight that provides illumination to the display portion.

19. The method of claim 18 wherein the circuit portion that extends outside the perimeter of the display portion comprises power circuits for providing power to the backlight.

20. The method of claim 19 wherein the connector comprises a USB port.
