Abstract
Various embodiments described herein involve making connections with the display leads on more than one side of the display array, e.g., on 2 sides, 3 sides or all 4 sides of the display array. By making connections with the display leads on more than one side of the display array, the available area for bonding leads and control circuitry may be increased. The driver chip(s), discrete components, and other active components necessary for addressing the display panel may be attached to the top or the bottom of a flexible printed circuit (“FPC”) or a similar device. Some embodiments involve attaching an FPC to the display such that that the backplate is substantially encased by the FPC.
Claims31
An apparatus, comprising:
- an array substrate;
- a display array disposed on the array substrate;
- a plurality of leads extending outward from the display array, the plurality of leads disposed over the array substrate in a plurality of lead areas surrounding the display array;
- a backplate attached to the array substrate;
- a first processor configured to send drive signals to the display array;
- a flexible substrate configured to convey the drive signals from the first processor to the plurality of leads, the flexible substrate substantially enclosing the backplate and being attached to at least two of the plurality of lead areas.
An apparatus, comprising:
- an array substrate;
- a display array disposed on the array substrate;
- a plurality of leads extending outward from the display array, the plurality of leads disposed over the array substrate in a plurality of lead areas surrounding the display array;
- a backplate attached to the array substrate;
- a first processor configured to send drive signals to the display array;
- a flexible substrate configured to convey the drive signals from the first processor to the plurality of leads, the flexible substrate being attached to each lead area of the plurality of lead areas.
A method, comprising:
- depositing a display array on an array substrate, the display array comprising a plurality of leads disposed in a plurality of lead areas of the array substrate;
- attaching a backplate to the array substrate such that the backplate covers the display array but does not entirely cover the plurality of leads;
- and
- affixing a flexible substrate to the plurality of leads in each of the plurality of lead areas, the flexible substrate configured to convey drive signals from a processor to the plurality of leads.
An apparatus, comprising:
- means for depositing a display array on an array substrate, the display array comprising a plurality of leads disposed in a plurality of lead areas of the array substrate;
- means for attaching a backplate to the array substrate such that the backplate covers the display array but does not entirely cover the plurality of leads;
- and
- means for affixing a flexible substrate to the plurality of leads in each of the plurality of lead areas, the flexible substrate configured to convey drive signals from a processor to the plurality of leads.
