Abstract:
A method for assembling a liquid crystal display includes fixing a liquid crystal panel and a touch panel together to form a touch display screen; inspecting the touch display screen; if no defect is identified in inspecting the touch display screen, fixing the touch display screen and a backlight unit together to form a touch display backlight module screen; and inspecting the touch display backlight module screen. The method for assembling the liquid crystal display helps reduce waste of backlight units and increases yield rate.
Abstract:
A curved backlight assembly includes a light source, a curved light guide plate (LGP), a heat-dissipating plate, a supporting plate and a connecting member. The light source is abutted with the curved LGP. The heat-dissipating plate and supporting plate are connected by the connecting member to thereby form a curved backplane. The curved LGP is arranged on the curved backplane. Connected ends of the heat-dissipating plate and supporting plate are formed with elongated slots. The connecting member penetrates through elongated slots to connect the heat-dissipating plate and the supporting plate. A dimension of the curved backplane is increased or decreased with a relative displacement between the heat-dissipating plate and supporting plate to match with expansion or contraction of the curved LGP. The present invention has a simple structure. An optical coupling distance between the light source and curved LGP is shortened and the light incidence efficiency is improved.
Abstract:
The present invention discloses a configuration structure for a front frame and a middle frame for use in a liquid crystal display device, and includes a front frame including a sidewall with a first tab and a first notch alternatively arranged. A middle frame is arranged with respect to the front frame, and includes a sidewall having a second notch corresponding to the first tab, and a second tab corresponding to the first notch, alternatively arranged; and wherein the first tab engages with the second notch, and the second tab engages with the first notch so as to securely interlock the front frame and the middle frame. The thickness made up by the sidewall of the front frame and the gap between the front frame and the middle frame is properly reduced, and this can effectively benefit the narrow-border of the liquid crystal display device. In addition, since the backboard is still there without being compromised, the overall mechanic strength of the liquid crystal display is greatly enhanced. On the other hand, since the sidewall of the front frame is directly in connection with the sidewall of the backboard on which the light source is mounted, the front frame can be properly served as a heatsink so as to improve the overall heat dissipation of the liquid crystal display device. The present invention further provides a liquid crystal display device incorporated with such a configurational structure.
Abstract:
The present invention is related to a technology of liquid crystal display, and specially to a fixture incorporated in a backlight module for the liquid crystal display. The fixture for backlight module comprises a backboard having a bottom board, a sidewall, and a bent portion. The sidewall has a first end and a second end, and the bottom board being interconnected with the first end. The bent portion is interconnected to the second end, and arranged on an outside of the sidewall, and creates an angle with respect to the sidewall. A plastic frame is defined with opening aligned and enveloped onto the bent portion so as to securely assemble the plastic frame to the backboard. The advanced and preferred interengagement between the backboard and the plastic frame can not only readily implement into the backlight module in which the light strip and backboard are made individually, but also can be fitted into the backlight module in which the backboar is integrally formed with driving circuit for light strip. The fixture can be readily facilitated by the existing technology and the assembly is easy while the overall configuration is robust and durable.

Abstract:
A display device includes a backlight module positioning adhesive structure and a liquid crystal panel that includes a bezel zone and a light transmitting zone. A backlight module includes a reflector plate, a light guide plate, and the optic film that are sequentially stacked on each other and surrounded by a mold frame. The backlight module further includes a double-sided adhesive tape that includes first and second layers stacked on each other. The second layer includes a light shielding section and a light transmitting section connected to the light shielding section. The double-sided adhesive tape is adhesively bonded between the bezel zone of the liquid crystal panel and the backlight module. The light shielding section is located on an edge portion of the optic film and the mold frame. The light transmitting section extends towards the light transmitting section of the optic film.
Abstract:
A liquid crystal display and a double sided tape therefor are provided. The liquid crystal display comprises: a liquid crystal panel; a backlight unit comprising a back plate, a set of optical films, and a frame; and a double sided tape comprising a first surface coated with a first adhesive and connected to the liquid crystal panel through the first adhesive, and a second surface coated with a second adhesive and connected to the back plate and the set of optical films respectively through the second adhesive. The adhesion strength of the first adhesive on the liquid crystal panel is lower than that of the second adhesive on the set of optical films. After the backlight unit is separated from the liquid crystal panel, the double sided tape can be left on the optical films and the frame. Therefore, the position relationship among the films within the set of optical films would not be damaged, ensuring that the reassembled liquid crystal display can work normally.
