Abstract
A display apparatus is provided. The display apparatus is suitable for a user to view through a polarization component having a first transmittance axis. The display apparatus includes a display module, a polarizer and a biaxial half-wave plate. The polarizer has a second transmittance axis such that a light provided from the display module passes through the polarizer and is converted into a polarized light. The biaxial half-wave plate is disposed on the display module and between the polarizer and the polarization component. The biaxial half-wave plate has a slow axis arranged between the first and second transmittance axes. The polarization of the polarized light passing through the biaxial half-wave plate tends toward the first transmittance axis.

A display apparatus suitable for a user to view through a polarization component
- having a first transmittance axis, comprising:
- a display module;
- a polarizer disposed on the display module, wherein the polarizer has a second transmittance axis such that a light from the display module passes through the polarizer and is converted into a polarized light;
- and
- a biaxial half-wave plate disposed on the display module and between the polarizer and the polarization component, wherein the biaxial half-wave plate has a slow axis arranged between the first and second transmittance axes, and the polarized light has a polarization passing through the biaxial half-wave plate and tending toward the first transmittance axis.
A display apparatus, comprising:
- a display module having a long edge and a short edge;
- a polarizer disposed on the display module, wherein the polarizer has a transmittance axis, and an included angle θp is formed between the transmittance axis and the long edge such that the a light from the display module passes through the polarizer and is converted into a polarized light;
- and
- a biaxial half-wave plate disposed on the display module, wherein the biaxial half-wave plate has a slow axis, and an included angle θ is formed between the slow axis and the long edge such that a polarization of the polarized light passing through the biaxial half-wave plate tends to be parallel with the short edge, and the transmittance axis and the slow axis satisfy |θp|<|θ|<90°.
A display apparatus, comprising:
- a display module;
- a polarizer disposed on the display module, wherein the polarizer has a transmittance axis such that a light from the display module passes through the polarizer and is converted into a polarized light;
- and
- a biaxial half-wave plate disposed on the polarizer, wherein the biaxial half-wave plate has a slow axis, and an included angle arranged between the transmittance axis and the slow axis is larger than 0° and smaller than 45°.
