Patent number: 10481406Abstract: A multi-view display is switchable between single view and multi-view modes, and uses lenticular means (9) arranged over the display panel which comprise birefringent electro-optic material (62) adjacent a non-switchable optically transparent layer (60). The non-switchable optically transparent layer (60) has a refractive index (n) substantially equal to the extra ordinary refractive index of the birefringent electro-optic material (62). In the single view mode, the birefringent electro-optic material (62) defines a non-switched state, and the polarization (64) of the light output from the display panel and incident on the lenticular means is linear and aligned with the optical axis of the birefringent electro-optic material (62) at the surface where the display output light is received. In the multi-view mode, the birefringent electro-optic material (62) defines a switched state in which the optical axis is aligned perpendicularly to the display output surface.Type: GrantFiled: September 6, 2017Date of Patent: November 19, 2019Assignee: Koninklijke Philips N.V.Inventors: Fetze Pijlman, Jan Van Der Horst

Patent number: 10401660Abstract: To acquire a fine viewing angle property from oblique view fields in a lateral electric field type liquid crystal display device having liquid crystal initial alignment directions in two orthogonal directions. The absorption axis of the incident-side polarization plate and the absorption axis of the exit-side polarization plate are orthogonal to each other in both of the region I and the region II, and the liquid crystal layer, the in-cell retarder as an optical compensation layer, the A-plate, and the C-plate sandwiched therebetween are in parallel to either one of the absorption axes or orthogonal to the substrates. Therefore, the transmittance can be suppressed to be low and a fine black display can be acquired even when the display surface is viewed from the oblique view fields.Type: GrantFiled: April 18, 2016Date of Patent: September 3, 2019Assignee: NLT TECHNOLOGIES, LTD.Inventors: Shinichi Nishida, Hidenori Ikeno, Hideki Ito, Mitsuhiro Sugimoto
