Title:
LIGHT GUIDE PLATE USING HYBRID PATTERN AND DISPLAY DEVICE INCLUDING SAME
Document Type and Number:
WIPO Patent Application WO/2023/106775
Kind Code:
A1
Abstract:
The present invention relates to a light guide plate using a hybrid pattern and a display device including the light guide plate. The light guide plate includes: multiple dot groups having a predetermined number of dot patterns, which disperse a light source incident from a light incident surface of a side surface thereof to the front surface thereof and are densely formed on a surface facing the front surface; and light dispersion dots provided in spaced spaces between the dot groups to disperse the light source incident to each of the spaces between the dot groups in multiple directions. The light guide plate enables light to uniformly reach a liquid crystal screen, and thus can minimize defects at the time of mass production of large-scale light guide plates, so as to improve display quality and productivity.
