A measurement method and a measurement device are disclosed. The measurement method is adapted to a 3D display capable of producing a plurality of viewing zones, which includes following steps. At least a part of a display area of the 3D display displays an image of one of the viewing zones. Light radiation amounts of a first position of the 3D display are detected with a light detector from different viewing angles. A viewing angle with a local maximum light radiation amount is taken as a reference viewing angle, a distance between the light detector and the 3D display along the reference viewing angle is changed, and light radiation amounts of a plurality of different second positions of the 3D display are detected in different distances. A distance at which light radiation amounts of the second positions are most uniform is taken as the optimal viewing distance.

Measurement method and measurement device

A three-dimensional image display device including a polarized light module, a non-vertical polarized light barrier grating unit and an image display unit is provided. The polarized light module provides a polarized light. The non-vertical polarized light barrier grating unit is disposed in a light path of the polarized light to modulate the polarized light into a modulated polarized light in interlaced lines for output. The image display unit receives the modulated polarized light from the non-vertical polarized light barrier grating unit, and outputs two or more images with parallax.

A micro fluidic module having at least a micro fluid channel barrier comprises at least an actuator, a firing chamber, a plurality of convergent fluid outlet channel and a plurality of convergent fluid inlet channel. The actuator (e.g. a heater) boils the working fluid and generates thermal bubble and instant high pressure to eject the working fluid outside and expel the working fluid through the fluid outlet channel. Then, the working fluid refills from the fluid inlet channel. Therefore, the working fluid flows consistently through the firing chamber. The working fluid flowing through adjacent firing chambers are arranged in different or consistent directions. Therefore, the refilling speed of the working fluid is increased, and the operating frequency of the module is improved.
