  • Publication number: 20220049836
    Abstract: A light diffusion plate is configured to be assembled with a blue light source module having blue Mini LEDs to form a white light backlight module. The light diffusion plate is added with organic dyes with light-emission wavelength of 490-650 nm in order to convert the blue light into white light. The light diffusion plate is made by a foaming extrusion process and contains a plurality of micro-bubbles with a size of 60-400 ?m and a weight-reduction ratio of 15-25% for improving the uniformity of white light and resolving the MURA problem. The size of micro-bubbles is controlled by reducing the temperature of at the exit end of the T-die head, such that the wavelength of the white light emitted from the light diffusion plate can be narrower to achieve the effect of wider color gamut display.

  • Patent number: 8703070
    Abstract: Apparatus for immunoassay includes: a cartridge, including at least one test unit; a pin-film assembly, having a second sealing film, a plurality of pierce mechanisms, and a first actuation unit; a plurality of magnetic particles; at least one first magnetic unit; and at least one second magnetic unit. The test unit includes a plurality of fluid chambers, a plurality of pin chambers, a microchannel structure, a buffer chamber, a detection chamber and a waste chamber. The first actuation unit drives the pierce mechanisms to enable a working fluid to flow into the detection chamber storing the magnetic particles. As the second magnetic unit has a magnetic force larger than that of the first magnetic unit and can move reciprocatingly between a third position and a fourth position, the magnetic particles are driven to move reciprocatingly inside the detection chamber, thereby fully mixing the magnetic particles with the working fluid.
