Electro-optical module, power supply substrate, wiring substrate, and electronic apparatus
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.
1. An electro-optical module, comprising:
an electro-optical panel that has a plurality of electro-optical elements;
a wiring substrate that is connected to the electro-optical panel, the wiring substrate including a driver generating a signal to be supplied to the electro-optical panel; and
a power supply substrate that generates a driving voltage driving the plurality of electro-optical elements,
the driving voltage being supplied from the power supply substrate to the wiring substrate through a connector portion disposed on the wiring substrate, and then to the electro-optical panel,
the wiring substrate being separate from the power supply substrate.
2. The electro-optical module according to claim 1 ,
the electro-optical panel having a first plane from which lights from the plurality of electro-optical elements exit and a second plane opposite to the first plane,
the power supply substrate being disposed on a side of the second plane.
3. The electro-optical module according to claim 1 ,
the electro-optical panel having a first plane from which lights from the plurality of electro-optical elements exit and a second plane opposite to the first plane,
the wiring substrate being disposed on a side of the second plane.
4. The electro-optical module according to claim 1 , wherein the wiring substrate is a flexible substrate.
5. The electro-optical module according to claim 4 , the power supply substrate being attached to the flexible substrate.
6. The electro-optical module according to claim 4 , the wiring substrate being attached to the flexible substrate.
7. The electro-optical module according to claim 4 , the wiring being attached to the flexible substrate.
8. The electro-optical module according to claim 4 , the flexible substrate being folded at least one time.
9. The electro-optical module according to claim 8 , the flexible substrate being folded at least two times.
10. The electro-optical module according to claim 9 , the flexible substrate being folded such that the flexible substrate sandwiches the power supply substrate.
11. 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.
