MUMBAI, India, Aug. 31 -- Intellectual Property India has published a patent application (202514114596 A) filed by Lg Display Co. , Ltd. on November 20, 2025, for Light Emitting Diode Display Device.
Inventor includes Lee Dae-Heung --.
The application for the patent was published on August 28, 2026, under issue no. 35/2026.
Abstract: Display device (100, 200, 400) includes display panel (101) including light emitting diode (D) in first to third emission areas (EA1, EA2, EA3) of first to third pixel regions (P1, P2, P3); transmittance variable layer (175) on display panel (101) and first to third spacers (180a, 180b, 180c) and light absorbing layer (178) in one of: space between and side surface of spacer (180), first to third spacers (180a, 180b, 180c) in emission areas (EA1, EA2, EA3); driving electrode layer (171) at one side of transmittance variable layer (175) and first and second driving electrodes (172, 173) in first and second non-emission areas (NEA1, NEA2); and touch electrode layer (181) at other side of transmittance variable layer (175) and first and second touch electrodes (182, 183) corresponding to first and second driving electrodes (172, 173). This enables light transmittance control to reduce ambient light reflection, maintain display brightness and integrate touch sensing. FIG. 3A
