  • Patent number: 12263643
    Abstract: A method includes flowing gas within a chamber for first process parameters at a predetermined point in a laser focal plane and simulating the step of flowing gas within the chamber based on the value of the flow characteristic of the gas at the predetermined point in the laser focal plane so that a value of a simulated-flow characteristic of the gas at a predetermined point away from the laser focal plane is identified. The method comprises comparing the value of the simulated-flow characteristic of gas at the predetermined point away from the laser focal plane to a desired value of the simulated-flow characteristic and flowing gas within the chamber for second differing process parameters, when the value of the simulated-flow characteristic of the gas at the predetermined point away from the laser focal plane differs from the desired value of the simulated-flow characteristic is outside a predetermined range.

  • Patent number: 12098840
    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.
