Head mounted display apparatus

A head mounted display (HMD) apparatus, comprising:

• a first lens and a second lens;
• a first micro-display disposed on the first lens;
• a second micro-display disposed on the second lens;
• a first light source for emitting a first incident light;
• a second light source for emitting a second incident light;
• and
• an eyeglass frame for carrying the first lens, the second lens, the first light source, and the second light source;
• wherein a first disposed direction of the first micro-display is upside-down to a second disposed direction of the second micro-display with respect to a center line of the eyeglass frame between the first lens and the second lens, such that a first side of the first micro-display corresponding a first rubbing alignment processing direction and a first side of the second micro-display corresponding a second rubbing alignment processing direction are symmetric with respect to the center line of the eyeglass frame between the first lens and the second lens;
• wherein the first incident light emitted by the first light source is obliquely emitted from the first side of the first micro-display toward the first micro-display and the second incident light emitted by the second light source is obliquely emitted from the first side of the second micro-display toward the second micro-display.

A head mounted display (HMD) apparatus, comprising:

• a first micro-display disposed on the first lens;
• a second micro-display disposed on the second lens;
• a first light source for emitting a first incident light;
• a second light source for emitting a second incident light;
• and
• an eyeglass frame for carrying the first lens and the second lens;
• wherein the first micro-display and the second micro-display are made by same manufacturing processes, such that a first rubbing alignment processing direction of the first micro-display is same as a second rubbing alignment processing direction of the second micro-display, such that a first side of the first micro-display corresponding to the first rubbing alignment processing direction and a second side of the second micro-display corresponding to the second rubbing alignment processing direction are symmetric with respect to a center line of the eyeglass frame between the first lens and the second lens;
• wherein the first incident light emitted by the first light source is obliquely emitted from the first side of the first micro-display toward the first micro-display and the second incident light emitted by the second light source is obliquely emitted from a first side of the second micro-display toward the second micro-display, wherein the first side and the second side of the second micro-display are opposite to each other.
