An investigation of a 2.48-inch LCD panel with 1,218 ppi, for Head-Mounted Display was successfully mass produced. The device using hybrid CMOS-LTPS and IGZO TFTs structure achieves high resolution and high transmittance simultaneously. The fabricated LCD panel is highly reliable, enduring 1,000 hours in aging tests, and has been mass-produced.
