Abstract

Presented here are manufacturing techniques to create an irregularly shaped electronic display, including a hollow within which a sensor, such as a camera, can be placed. The manufacturing techniques enable the creation of the hollow anytime during the manufacturing process. The resulting electronic display occupies the full side of the mobile device, with the sensors placed within and surrounded by the display.

First claim

The invention claimed is:

1. A method comprising:
providing a mask corresponding to a plurality of layers in an electronic display, wherein the plurality of layers comprises a color filter (CF) layer, a display layer, and a thin film transistor (TFT) layer;
providing the CF layer comprising a CF substrate and a plurality of color regions disposed on the CF substrate;
providing the display layer comprising a plurality of display elements disposed between the CF layer and the TFT layer, the plurality of display elements configured to transmit light;
providing the TFT layer comprising a TFT substrate and a plurality of transistors disposed on the TFT substrate;
forming a hollow from within the CF layer, the display layer, and the TFT layer, wherein the hollow associated with the CF layer, the display layer, and the TFT layer, corresponds to the mask;
sealing the CF layer, the display layer, and the TFT layer to obtain a combined layer; and
disposing a sensor inside the removed hollow.

2. The method of claim 1 , said providing the TFT layer comprising:
distributing a plurality of thin film transistors on the hollowed TFT substrate; and
distributing a plurality of row and column electrodes corresponding to the plurality of thin film transistors such that each row and column electrode in the plurality of row and column electrodes interrupted by the hollow circumvents the hollow.

3. The method of claim 1 , said providing the CF layer comprising:
depositing a colored photoresist coating onto the CF substrate;
based on the mask, modifying a photomask to comprise a plurality of protected areas, and a plurality of unprotected areas, wherein the mask is associated with the plurality of unprotected areas; and
removing the plurality of unprotected areas to leave the colored photoresist coating disposed on the CF substrate in the plurality of protected areas.

4. The method of claim 1 , said providing the display layer comprising:
depositing a sealant on a layer in the plurality of layers, said depositing comprising tracing at least a partial outline associated with the electronic display and an outline associated with the mask; and
depositing a plurality of liquid crystal beads inside the outline.

5. The method of claim 1 , wherein said forming the hollow comprises:
laser cutting the hollow from the CF layer, the display layer, and the TFT layer, wherein the hollow associated with the CF layer, the display layer, and the TFT layer corresponds to the mask.

6. The method of claim 1 , wherein said sealing the CF layer, the display layer, and the TFT layer comprises:
upon said forming the hollow, combining the CF layer, the display layer, and the TFT layer to obtain the combined layer.

7. The method of claim 1 , wherein the mask comprises a circle.

8. The method of claim 1 , the sensor comprising at least one of a camera, an ambient light sensor, or a proximity sensor.

9. The method of claim 1 , wherein the display layer comprises a liquid crystal display (LCD) layer, the LCD layer comprising an LCD substrate and a plurality of liquid crystals disposed on the LCD substrate.

10. The method of claim 1 , wherein the display layer comprises an organic light emitting diode (OLED) layer, the OLED layer comprising an OLED substrate and a plurality of OLEDs disposed on the OLED substrate.

11. The method of claim 1 , wherein the display layer comprises a micro-electromechanical systems (MEMS) layer, the MEMS layer comprising a MEMS substrate and a plurality of MEMS disposed on the MEMS substrate.

12. The method of claim 1 , said forming the hollow comprising:
forming the hollow within a polarizer layer, the CF layer, the display layer, and the TFT layer, wherein the hollow associated with the polarizer layer, the CF layer, the display layer, and the TFT layer corresponds to the mask.
