Patent number: 11873975Abstract: A backlight module comprises a back frame with at least one perforation, a light board arranged on the back frame, a plurality of light-emitting elements arranged on the light board at intervals, a fixing frame combined with the back frame, and a plurality of optical films stacked on the fixing frame. The light board has at least one through portion, and the position of the through portion corresponds to the at least one perforation of the back frame. A part of the fixing frame is positioned in the at least one perforation of the back frame through the at least one through portion of the light board. The effect of a narrow frame can be effectively achieved by arranging the joint part of the fixing frame and the back frame on the inner side of the back frame and forming the through portion on the edge of the light board to be engaged with the joint part of the fixing frame and the back frame. The present invention also provides a display device comprising the backlight module.Type: GrantFiled: March 23, 2023Date of Patent: January 16, 2024Assignee: Radiant Opto-Electronics CorporationInventors: Yi-Jen Chiu, Sung-Fu Wu, Jung-Yin Chang, Ya-Yin Tsai

Publication number: 20230375771Abstract: A curved backlight module includes a frame unit, a light source, and a diffuser plate. The frame unit includes a back frame, a curvature fixing member combined with the back frame, and at least one first positioning structure. The at least one first positioning structure is disposed on anyone of the back frame or the curvature fixing member. The curvature fixing member presses the diffuser plate so that at least a portion of the diffuser plate has the same curvature with the curvature fixing member. The diffuser plate has at least one second positioning structure, the at least one first positioning structure of the frame unit is combined with the at least one second positioning structure of the diffuser plate to limit the diffuser plate and simplify the structure of the positioning elements. The curvature fixing member stably maintains the curvature of the diffuser plate, thereby improving the overall structural stability and optical quality.Type: ApplicationFiled: April 29, 2023Publication date: November 23, 2023Applicant: Radiant Opto-Electronics CorporationInventors: Hui-Hua HUNG, Ying-Ting CHEN, Sung-Fu WU, Yi-Jen CHIU

Patent number: 11681089Abstract: An optical film is disclosed. The optical film is divided into a main body and two extending portions arranged along a second direction by two imaginary lines which are extended along a first direction and parallel to each other, wherein the second direction is substantially perpendicular to the first direction. The main body is located between the two extending portions. Each of the extending portions has an abutting edge. A first length W0 of the main body along the first direction is greater than a second length W1 of the abutting edge along the first direction.Type: GrantFiled: April 7, 2022Date of Patent: June 20, 2023Assignees: RADIANT(GUANGZHOU) OPTO-ELECTRONICS CO., LTD, RADIANT OPTO-ELECTRONICS CORPORATIONInventors: Yi-Jen Chiu, Sung-Fu Wu, Ying-Ting Chen

Patent number: 10191316Abstract: A coupling mechanism includes a back plate and a frame unit. The back plate is formed with at least one engaging hole. The frame unit has at least one frame body, and at least one engaging member extending from the at least one frame body, and engaging the at least one engaging hole for coupling fixedly the at least one frame body to the back plate. The at least one frame body is deformable for disengaging the at least one engaging member from the at least one engaging hole, thereby permitting removal of the at least one frame body from the back plate.Type: GrantFiled: March 1, 2017Date of Patent: January 29, 2019Assignees: RADIANT OPTO-ELECTRONICS (SUZHOU) CO.

Patent number: 9581758Abstract: A backlight module includes a frame structure, a heat sink, a light source and a light guiding plate. The frame structure includes a cover unit that defines an airgap therein. The heat sink is located below the airgap of the cover unit. The light source directly contacts the heat sink. The light guiding plate is disposed to correspond in position to the light source for receiving light emitted from the light source. The heat sink is located between the light guiding plate and the cover unit.Type: GrantFiled: October 22, 2015Date of Patent: February 28, 2017Assignee: RADIANT OPTO-ELECTRONICS CORPORATIONInventors: Chien-Hung Chen, Teng-Yi Huang, Yung-Chieh Chao, Sung-Fu Wu
