Abstract

A compact display assembly includes a flexible display screen such as a passive LCD screen or an OLED display screen. Printed circuit boards including driving circuitry for the display screen are mounted at its rear in a configuration defining a longitudinal region of the screen about which it may be folded or curved over on itself to a compact configuration. The assembly may be included in electronic computational devices such as laptop computers, electronic books and the like.

Claims

1. A flexible display assembly comprising:

a flexible display screen having a plurality of connection points;

at least two printed circuit boards (PCB'"'"'s) having edges adapted for electrical connection to the connection points of the flexible display screen; and

,

a plurality of flexible connectors extending between a portion of the edge of each PCB and a portion of the connection points;

such that,

the portion of the edge of each PCB can move relative to the portion of the connection points to allow the flexible display screen to fold about a region between the PCB'"'"'s.

2. An assembly according to claim 1, wherein the flexible display screen is rectangular and the connection points are located on three sides of the screen.

3. An assembly according to claim 2, wherein two of the rectangular screen'"'"'s sides are longer than the other two sides and the region about which the rectangular screen folds is a strip extending between the mid points of the screen'"'"'s longer sides.

4. An assembly according to claim 3, wherein a first edge of each of the PCB'"'"'s is the same length and parallel to the shorter sides of the rectangular screen and a second edge of each of the PCB'"'"'s is half the length of the longer sides of the rectangular screen and angled thereto;

wherein,

the portion of the edge of each PCB which is connected to the flexible connectors is positioned on the second edge.

5. An assembly according to claim 1, wherein said screen comprises a flexible liquid crystal display.

6. An assembly according to claim 1, wherein said screen comprises an organic light emitting diode display.
