Abstract

An integrated display panel (IDP) is created by integrating two or more modified component display panels. Each of the two or more modified component display panels include an active region, which may be extended until at least one of the edges. A first set of layers of a first modified component display panel and a second set of layers of the second modified is removed along an edge while manufacturing the first and second modified component display panels. The first and the second modified component display panels are overlapped along the edge to form a junction. At the junction, the back light from a lower layer is allowed to pass through until it reaches a top layer of the IDP. The graphics is displayed, seamlessly, in an active area of the IDP without forming a dark band at the junction of the first and the second modified component display panel.

Claims

wherein a first set of layers of the first modified component display panel is removed along the at least one of the edges while the first modified component display panel is manufactured,

wherein a second set of layers of the second modified component display panel is removed along the at least one of the edges, while the second modified component display panel is manufactured, wherein the second set of layers do not include a layer that is included in the first set of layers,

wherein the first modified component display panel is overlapped with the second modified component display panel along the at least one of the edges to form a junction,

wherein a back light from a lower layer at the junction is allowed to pass through an overlapping area of the first set of layers and the second set of layers and reach a top layer of the integrated display panel,

wherein graphics is displayed, seamlessly, in an active area of the integrated display panel without forming a dark band at the junction of the first and the second modified component display panel.

2. The integrated display panel of claim 1, wherein the first set of layers and the second set of layers together form a complete set of layers of the integrated display panel.

3. The integrated display panel of claim 1, wherein the plurality of modified component display panels further include a third and fourth modified component display panels,
