Abstract
Exemplary embodiments include a backlight assembly for an electronic display wherein said backlight assembly is comprised of a plurality of tiles. Each tile has a plurality of lights attached to it, such that when a single light or group of lights fail, the tile may be replaced without having to replace the entire backlight assembly. The lights in the assembly may be any one of the following: light emitting diodes (LED), organic light emitting diodes (OLED), field emitting display (FED), light emitting polymer (LEP), and organic electro-luminescence (OEL). Embodiments also allow tiles to be removed from the rear of the display and dissipate heat from the lights to the rear of the backlight assembly.
Claims5
A method for replacing a selected PCB within an LED backlight having a movable element placed behind the LED backlight assembly and having at least one edge;
- a hinge at one edge of the movable element so that the movable element can rotate to allow access to a rear portion of the LED backlight assembly;
- and electrical devices attached to the movable element such that rotation of the movable element causes the electrical devices to move accordingly, where the electrical devices are also in electrical communication with the image assembly, the method comprising the steps of:
- accessing the rear portion of the backlight,
- removing a securing element which holds the selected PCB in place, wherein the securing element is removed in a rearward direction;
- removing the selected PCB from the mounting structure, wherein the selected PCB is removed from the rear of the backlight;
- removing the electrical connection of the selected PCB;
- connecting the electrical connection of a replacement PCB;
- placing the replacement PCB within the mounting structure;
- and
- replacing the securing element.
