Micro-projection system
View Patent ↗A micro-projection system applied to a portable electronic device, comprising an optical engine, a control module, and a flat cable. The optical engine projects an image. The control module provides at least one control signal to control the optical engine. The flat cable is detachably connected to the optical engine and the control module respectively. Wherein, the optical engine and the control module are configured in the portable electronic device separately, and the flat cable has a corresponding configuration state for connecting the optical engine to the control module.
1. A micro-projection system applied to a portable electronic device, comprising:
an optical engine projecting an image, wherein the optical engine comprises a light source module configured to generate an image light beam, an optical projection module configured to project the image light beam on a projection surface to form the image, and at least one first connection port electrically connected to the light source module and the optical projection module;
a control module providing at least one control signal to control the optical engine; and
a flat cable detachably connected to the optical engine and the control module respectively;
wherein the optical engine and the control module are configured in the portable electronic device separately, and the flat cable has a corresponding configuration state for connecting the optical engine to the control module,
wherein the at least one first connection port is configured to transmit a driving control signal of the at least one control signal to the light source module and transmit a projection control signal of the at least one control signal to the optical projection module.
2. The micro-projection system according to claim 1 , wherein the control module comprises:
a projection control circuit configured to provide at least one control signal; and
at least one second connection port electrically connected to the projection control circuit and the flat cable, and configured to transmit the at least one control signal to the flat cable.
3. The micro-projection system according to claim 2 , wherein the flat cable has at least one first plug and at least one second plug, the at least one first plug is electrically connected to the at least one first connection port and the at least one second plug is electrically connected to the at least one second connection port.
4. The micro-projection system according to claim 3 , wherein the at least one first connection port and the at least one second connection port have the same port style, and the at least first plug and the at least one second plug have the same plug style.
5. A micro-projection system applied to a portable electronic device, comprising:
an optical engine projecting an image;
a control module providing at least one control signal to control the optical engine; and
a flat cable detachably connected to the optical engine and the control module respectively;
wherein the optical engine and the control module are configured in the portable electronic device separately, and the flat cable has a corresponding configuration state for connecting the optical engine to the control module,
wherein the flat cable has a first configuration state when a relative position between the optical engine and the control module is a first configuration relative position in the portable electronic device, and the flat cable has a second configuration state when the relative position between the optical engine and the control module have a second configuration relative position in the portable electronic device.
6. The micro-projection system according to claim 5 , wherein when the first configuration relative position is different from the second configuration relative position, the first configuration state is different from the second configuration state.
