Patent number: 11275265Abstract: Color conversion films for a LCD (liquid crystal display) having RGB (red, green, blue) color filters, as well as such displays, formulations, precursors and methods are provided, which improve display performances with respect to color gamut, energy efficiency, materials and costs. The color conversion films absorb backlight illumination and convert the energy to green and/or red emission at high efficiency, specified wavelength ranges and narrow emission peaks. Film integration and display configurations further enhance the display performance with color conversion films utilizing various color conversion elements and possibly patterned and/or integrated with a crosstalk blocking matrix. For example, color conversion and/or assistant dyes may be used to enhance spectral regions transmitted through the color filters and shape the illumination spectrum, to improve efficiency and performance.Type: GrantFiled: August 31, 2017Date of Patent: March 15, 2022Assignee: MOLECULED LTD.Inventors: Daniel Szwarcman, Ziv Sobol

Publication number: 20210191198Abstract: LCDs (liquid crystal displays) with improved efficiency and performance, as well as corresponding methods are disclosed. Color conversion films and elements with rhodamine-based fluorescent compounds and/or assistant dyes are used to modify the spectrum of the illumination provided by the backlight unit in either or both the backlight unit itself and the LCD panel, in various configurations. Color conversion may be performed above the LC module, possibly by a patterned layer incorporating the color filters, and/or within the backlight unit within a fluorescence-intensifying section in which radiation is recycled to enhance color conversion. Film configuration, positions and optionally supportive structures are provided, to extend the lifetime of the fluorescent compounds. Collimation of backlight illumination may further enhance the optical performance of disclosed LCDs.Type: ApplicationFiled: December 18, 2019Publication date: June 24, 2021Applicant: MolecuLED Ltd.Inventors: Sanaa MUSA, Rony SCHWARZ, Eran SELLA, Daniel SZWARCMAN, Maxim LIBERMAN, Evgenia Liel (Jeny) KUKS, Ziv SOBOL, Daniel ARONOV, Mor Shmuel ARMON, Elad Cohen

Patent number: 10519314Abstract: Color conversion films for a LCD (liquid crystal display) having RGB (red, green, blue) color filters, as well as such displays, formulations, precursors and methods are provided, which improve display performances with respect to color gamut, energy efficiency, materials and costs. The color conversion films absorb backlight illumination and convert the energy to green and/or red emission at high efficiency, specified wavelength ranges and narrow emission peaks. For example, rhodamine-based fluorescent compounds are used in matrices produced by sol gel processes and/or UV (ultraviolet) curing processes which are configured to stabilize the compounds and extend their lifetime—to provide the required emission specifications of the color conversion films. Film integration and display configurations further enhance the display performance with color conversion films utilizing various color conversion elements.Type: GrantFiled: November 16, 2016Date of Patent: December 31, 2019Assignee: StoreDot Ltd.Inventors: Daniel Szwarcman, Elad Cohen, Mor Shmuel Armon, Evgenia Leil (Jeny) Kuks, Rony Schwarz, Elena Eisurovich, Daniel Aronov, Eran Sella
