Abstract

An electronic device including a display assembly is provided. In some embodiments, the electronic device includes a flex conductor electrically connecting a display integrated circuit and a circuit board. The flex conductor may have a display end including first and second connectors separated by a space and a circuit board connector end including a third connector opposite from the display connector end.

Claims (52)

1. A touch display system, comprising:

a display substrate having a front major face and a back major face;

a display integrated circuit mounted to the display substrate;

a circuit board including a processor oriented behind the back major face of the display substrate; and

a flex conductor electrically connected to the display integrated circuit and the circuit board, the flex conductor having:

(i) a display connector end including a first connector and a second connector, the first connector and the second connector being separated by a distance defining a space where the flex conductor is not present, and

(ii) a circuit board connector end including a third connector opposite from the display connector end,

wherein the first connector and the second connector are connected to the display integrated circuit and the third connector is connected to the circuit board; and

wherein an electrical component that is not directly electrically connected to the flex conductor is located between the first connector and the second connector.

2. The system of claim 1 , wherein the display substrate defines a central, longitudinal axis passing parallel to the front and back major faces, and the central, longitudinal axis intersects the display integrated circuit.

3. The system of claim 2 , wherein the central, longitudinal axis does not intersect the flex conductor at the connection with the display integrated circuit.

4. The system of claim 2 , wherein the display integrated circuit is centered about the central, longitudinal axis.

5. The system of claim 4 , wherein the first connector and the second connector are positioned symmetrically about the central, longitudinal axis.

6. A touch display system, comprising:

a display substrate having a front major face and a back major face;

a display integrated circuit mounted to the display substrate;

a circuit board including a processor oriented behind the back major face of the display substrate; and

a flex conductor electrically connected to the display integrated circuit and the circuit board, the flex conductor having:

(i) a display connector end including a first connector and a second connector, the first connector and the second connector being separated by a distance defining a space, and

(ii) a circuit board connector end including a third connector opposite from the display connector end,

wherein the first connector and the second connector are connected to the display integrated circuit and the third connector is connected to the circuit board;

wherein the display end of the flex conductor has a width (W), and the distance defining the space is between 0.2*width (W) and 0.8*width (W); and

wherein an electrical component that is not directly electrically connected to the flex conductor is located between the first connector and the second connector.

7. A touch display system, comprising:

a display substrate having a front major face and a back major face;

a display integrated circuit mounted to the display substrate;

a circuit board including a processor oriented behind the back major face of the display substrate; and

a flex conductor electrically connected to the display integrated circuit and the circuit board, the flex conductor having:

(i) a display connector end including a first connector and a second connector, the first connector and the second connector being separated by a distance defining a space, and

(ii) a circuit board connector end including a third connector opposite from the display connector end,

wherein the first connector and the second connector are connected to the display integrated circuit and the third connector is connected to the circuit board;

wherein an electrical component that is not directly electrically connected to the flex conductor is located between the first connector and the second connector.

8. The system of claim 1 , wherein a recessed connector receptacle configured to receive a connector of a cable that connects the electronic device to an external component is located in the space between the first connector and the second connector.

9. The system of claim 1 , wherein a component selected from the group consisting of a microphone, speaker, sensors, fingerprint sensor, proximity sensor, accelerometer, camera, and flash device is located in the space between the first connector and the second connector.

10. The system of claim 1 , wherein the display integrated circuit is mounted to the front major face of the display substrate and the flex conductor wraps around the display substrate from the front major face to the back major face.

11. The system of claim 1 , wherein the circuit board is a printed circuit board.

12. The system of claim 1 , wherein the circuit board is a flexible circuit.

13. A touch display system, comprising:

a display substrate having a front major face and a back major face;

a circuit board including a processor oriented behind and parallel to the back major face of the display substrate;

a flex conductor electrically connecting the display substrate and the circuit board, the flex conductor having a display end including a first connector and a second connector separated by a distance defining a space where the flex conductor is not present and a circuit board connector end including a third connector opposite from the display connector end; and

a display integrated circuit mounted on the flex conductor;

wherein the first and second connectors are electrically connected with the display substrate and the third connector is electrically connected with the circuit board; and

wherein an electrical component that is not directly electrically connected to the flex conductor is located between the first connector and the second connector.

14. The system of claim 13 , wherein the display substrate defines a central, longitudinal axis passing parallel to the front and back major faces, and the central, longitudinal axis intersects the display integrated circuit.

15. The system of claim 14 , wherein the central, longitudinal axis does not intersect the flex conductor at the connection with the display substrate.

16. The system of claim 13 , wherein the display end of the flex conductor has a width (W), and the distance defining the space is between 0.2*width (W) and 0.6*width (W).

17. The system of claim 13 , wherein a recessed connector receptacle configured to receive a connector of a cable that connects the electronic device to an external component is located between the first connector and the second connector.

18. A method of manufacturing a display assembly, comprising:

connecting a first connector and a second connector of a flex conductor to a display integrated circuit of a display assembly, the first and second connectors separated by a distance defining a space where the flex conductor is not present and positioned at an opposite end of the flex conductor from a third connector, wherein an electrical component that is not directly electrically connected to the flex conductor is located between the first connector and the second connector;

connecting the third connector to a circuit board; and

enclosing the flex conductor and circuit board within a housing of an electronic device.
