Patent number: 11955473Abstract: To prevent an electrostatic damage on a display device formed with a driving circuit. Protective circuits are provided not only at input terminal parts, but also at intermediate parts of a circuit or at the ends of wiring lines. Otherwise, the protective circuits are provided at the ends of the wiring lines and at the places immediately before and after the input terminals, respectively, and then the circuit is interposed therebetween. Further, the protective circuits are provided around a circuit with a large current consumption.Type: GrantFiled: June 13, 2022Date of Patent: April 9, 2024Assignee: 138 East LCD Advancements LimitedInventor: Yutaka Kobashi

Patent number: 11587495Abstract: This invention provides an electro-optical module with reduced noise in driving voltage. The invention can include a power supply substrate that is arranged separately from the flexible substrate having a driver, so that the noise of the driving voltage supplied from the power supply substrate is reduced. The electro-optical module includes a first connecting portion connecting a first end of the flexible substrate to a display panel and configured to receive a signal from the driver, and a second connecting portion connecting the first end of the flexible substrate to the display panel and configured to receive the driving voltage from a third connecting portion at a second end of the flexible substrate.Type: GrantFiled: October 13, 2021Date of Patent: February 21, 2023Assignee: 138 EAST LCD ADVANCEMENTS LIMITEDInventor: Tadashi Yamada

Patent number: 11042055Abstract: In a liquid crystal display device, a reflecting surface is attached to a portion, which overlaps with a periphery portion of a light guiding plate where the light incident section is position in a surface on the light guiding plate side in the dispersing sheet which is positioned farthest to the light guiding plate side among a plurality of optical sheets which are positioned between the light guiding plate and a liquid crystal panel. As a result, light which is emitted from the periphery portion of the light guiding plate is returned into the light guiding plate by being reflected by the reflecting surface, and after this, is emitted as illumination light from a light emitting surface while progressing within the light guiding plate.Type: GrantFiled: May 26, 2017Date of Patent: June 22, 2021Assignee: 138 East LCD Advancements LimitedInventors: Yoichi Momose, Nobutaka Urano

Patent number: 10901133Abstract: An illuminating device includes light emitting elements extending in a lengthwise direction and a light guide plate having a first principal surface for emitting light from the light emitting elements and a second principal surface facing the first principal surface. The light guide plate has light guide regions corresponding to the light emitting elements. The light emitting elements overlap the light guide plate on a side of the second principal surface of the light guide plate in plan view. The side of the second principal surface of the light guide plate has first sectional surfaces, on which light originated from each of the light emitting elements is incident. The side of the second principal surface of the light guide plate has second sectional surfaces, each having a reflection surface for reflecting the light originated from each light emitting element toward the first sectional surface, corresponding to the light emitting elements.Type: GrantFiled: September 29, 2014Date of Patent: January 26, 2021Assignee: 138 East LCD Advancements LimitedInventor: Osamu Yokoyama

Patent number: 10754204Abstract: A method of manufacturing a liquid crystal device having a first substrate and a second substrate facing each other with a liquid crystal layer interposed therebetween, and a sealing member formed in a peripheral portion of at least one of the substrates. The method includes forming the sealing member, disposing the liquid crystal layer inside the sealing member, and bonding the first substrate to the second substrate. In forming the sealing member, a ring-shaped portion that seals the liquid crystal layer inside the sealing member, a first sealing layer and a second sealing layer that face each other to be separated from each other are formed. In the bonding of the first substrate to the second substrate, a junction portion is formed in which the first and second sealing layers are pressed and joined outside the sealing member so as to form the ring-shaped portion.Type: GrantFiled: August 30, 2017Date of Patent: August 25, 2020Assignee: 138 East LCD Advancements LimitedInventors: Yoichi Momose, Satoshi Hasegawa
