Color filter and display panel using same

摘要

A color filter of display panel for converting dual band white backlight to light with three-primary colors. The color filter includes a plurality of first filtering parts, a plurality of second filtering parts, and a plurality of quantum dot blocks. The first filtering parts have a first primary color and allow light having a first wavelength corresponding to the first primary color to pass therethrough. The second filtering parts have a second primary color and selectively allow light having a second wavelength corresponding to the second primary color to pass therethrough. The quantum dot block converting light having a wavelength smaller than a third wavelength corresponding to a third primary color to light having the second wavelength.

1. A display panel comprising:
a lighting device configured to emit dual band white backlight comprising blue and green band light and yellow band light; and a color filter configured to convert the dual band white backlight to light composed of three-primary colors, the color filter comprising a plurality of first filtering parts having a green color, a plurality of second filtering parts having a blue color, and a plurality of quantum dot blocks, the first filtering parts being made of a photoresist material comprising dye with green color; the first filtering parts being configured to selectively allow light having a green color to pass therethrough; the second filtering parts being made of a photoresist material comprising dye with blue color; the second filtering parts being configured to selectively allow light having a blue color to pass therethrough; the quantum dot blocks being red quantum dot blocks; and the quantum dot blocks being configured to convert a part of green light of the dual band white backlight to red light.
