Patent number: 10393950Abstract: A backlight module having better heat dissipation, includes a backboard, a frame coupled to a peripheral area of the backboard, at least one light source, and a thermally conductive layer located on the backboard. The backboard is made of a thermally conductive material. The at least one light source is embedded in the thermally conductive layer and in direct contact with the thermally conductive layer which removes heat as it is generated by the light source.Type: GrantFiled: September 8, 2016Date of Patent: August 27, 2019Assignee: HON HAI PRECISION INDUSTRY CO., LTD.Inventors: Wen-Chin Lo, Chun-Yun Pan, Sin-Tung Huang, Chien-Yu Wei

Patent number: 10261235Abstract: A display apparatus which is not subject to light leakage from a cut edge of a quantum dot layer includes a display panel and a backlighting module. The backlight module includes light source, light guide plate, and quantum dot enhancement layer. The quantum dot enhancement layer has functional and invalidation portions. The functional portion converts light from the light guide plate into predetermined wavelengths. The invalidation portion is formed in the non-display region, and is unable to convert light from the light guide plate into predetermined wavelengths. A distance between a side surface of the invalidation portion and a side surface of the main display region is larger than or equal to a predetermined distance. The effect of the predetermined distance is to prevent the light leaking or transmitted from the invalidation portion from entering the display region at normal viewing angles.Type: GrantFiled: May 25, 2017Date of Patent: April 16, 2019Assignee: HON HAI PRECISION INDUSTRY CO., LTD.Inventors: Wen-Chin Lo, Chun-Yun Pan, Sin-Tung Huang, Chien-Yu Wei

Patent number: 9880344Abstract: A display apparatus utilizing all light output by a light source also includes a display panel with a shield portion, a light guide plate, and a quantum dot enhancement layer. The display panel includes a display portion and a shield portion. The light guide plate is parallel with the display panel and guides light emitted by the light source to the display panel. The quantum dot enhancement layer converts a wavelength of the light and the shield portion is configured to reflect stray or escaping light back into the quantum dot enhancement layer for conversion. The surface of the light guide plate is overlapped with the shield portion for preventing any light leakage and the mixing of light of different wavelengths and thus colors is increased and improved.Type: GrantFiled: December 15, 2016Date of Patent: January 30, 2018Assignee: HON HAI PRECISION INDUSTRY CO., LTD.Inventors: Wen-Chin Lo, Chien-Yu Wei, Chun-Yun Pan, Sin-Tung Huang
