Abstract

This invention provides an electro-optical module with reduced noise in driving voltage. The invention can include a power supply substrate that is arranged separately from the flexible substrate having a driver, so that the noise of the driving voltage supplied from the power supply substrate is reduced.

Claims (21)

1. An electro-optical module, comprising:

an electro-optical panel that has a plurality of pixels;

a wiring substrate that is connected to the electro-optical panel;

a driver that generates a signal to be supplied to the electro-optical panel; and

a power supply substrate that generates a driving voltage driving the plurality of pixels,

the driving voltage being supplied from the power supply substrate to the electro-optical panel through the wiring substrate,

the wiring substrate being separate from the power supply substrate.

2. The electro-optical module according to claim 1 ,

the signal generated by the driver being a data signal.

3. The electro-optical module according to claim 1 ,

the driving voltage being supplied to the electro-optical panel without passing through the driver.

4. The electro-optical module according to claim 1 ,

the electro-optical panel having a first plane from which lights from the plurality of pixels exit and a second plane opposite to the first plane,

the wiring substrate being disposed on a side of the second plane.

5. The electro-optical module according to claim 1 , wherein the wiring substrate is a flexible substrate.

6. The electro-optical module according to claim 5 , the power supply substrate being attached to the flexible substrate.

7. The electro-optical module according to claim 5 , the flexible substrate being folded at least one time.

8. The electro-optical module according to claim 1 , the driving voltage being supplied directly from the power supply substrate to the electro-optical panel through the wiring that is not connected to the driver.

9. The electro-optical module according to claim 8 , the flexible substrate being folded such that the flexible substrate sandwiches the power supply substrate.

10. The electro-optical module according to claim 9 , the flexible substrate being folded at least two times.

11. Electric equipment comprising the electro-optical module according to claim 1 .
