Abstract: A mold frame contains a lamp shade and a light source, a light guide being erected at the open end and secured in place on one side of the lamp shade; streams of light from the light source entering into from one side of the light guide plate to project in the direction as expected; and a mask device being disposed on the mold frame at where close to the joint edge of the light guide plate so to weaken the reflection rate of the light that leaves the light guide plate, to reduce the interference of the light in the light guide plate, and to diminish the phenomenon of ripples.

Abstract: A light guide plate locating construction includes a frame containing a mask and light tube with the light guide plate mounted at the open end of the mask; light permeating through one side of the light guide plate to project in the anticipated direction; locating holes being disposed at the top of the opening end of the mask; a retainer being inserted into the hole; the retainer including a locating portion and an interfering portion extending from the locating portion to the open end of the mask to hold against the edge of the light guide plate to protect the tube from being hit by the light guide plate.

Abstract: An orthogonal array backlight module includes multiple fluorescent tubes paved on both inner sides of a light box, and a display panel comprised of diffuser plate, optical film and liquid crystal panel being provide on the top of the light box; and each fluorescent tube being significantly shorter than that of the prior art of same size to effectively provide consistent luminance and allow easier assembly.

Abstract: A light equalizing structure installs a plurality of reflective sections on a reflective panel of a backlight module for reflecting the light emitted by a light source towards a panel assembly, and each reflective section keeps a predetermined distance from the light source. The height of each reflective section is directly proportional to the distance from its light source. In other words, there is a predetermined height difference for every two adjacent reflective sections, so that the light emitted from different angles of the light source can be reflected evenly from each reflective section on the reflective panel towards the panel assembly to achieve the effect of providing even brightness for each section of the panel assembly.

Abstract: At least one light distribution device is provided in the spacing between adjacent light sources to allow light diffused from both sides of the light sources to be properly refracted and reflect so as to more evenly diffuse light toward a diffuser plate and thereby, eliminate the dark bands between adjacent light sources for effectively solving the bright bands and dark bands problem observed in prior art LCD modules.

Abstract: A backlight module installs a light guide plate, a plurality of optical films, and a liquid crystal display panel in order on an emergent plane of a light source, wherein the light guide plate forms more than one hollow layer within an incident side to an effective light emitting area, such that the hollow layer of the light guide plate changes the light path of the light of the light source to effectively distribute and evenly emit the light towards each optical film. As a result, the dark band in each light source can be eliminated, the issue of having dark and bright bands according to the prior arts can be overcome effectively, and the light performance including luminance and evenness can be enhanced.

Abstract: An optical wave-guide device is provided between a light source and a lower diffuser for deflecting and reflecting the light passing through the optical wave-guide device so that the light is consistently diffused through the lower diffuser without creating any blind area among light sources to effectively solve the prior art problem of displaying bright bands and dark bands on the LCD.

Abstract: The present invention describes a backlight module that includes a lamp, a diffuser, an optical film and a liquid crystal display panel installed in sequence between a reflective mask and a diffuser, and the reflective mask has a light transmission window at the bottom, and the light transmission window includes a dimmer, an optical film and a sub liquid crystal display panel installed in sequence outside the light transmission window, so that a light is evenly emitted from the upper and lower liquid crystal display panels and sub liquid crystal display panels. The invention not only simultaneously displays screens, but also improves the light application rate.

Abstract: A backlight module has two lighting sides installed inside a casing. Two sides of the casing are installed with a main display screen and a sub-display screen. The backlight module comprises at least one light source; a light guile plate for guiding light from the light source to the main display screen and the sub-display screen. A lower diffusion sheet, a first light enhancing sheet and preferably, an upper diffusion sheet are installed between the main display screen and the light guide plate. A reflective sheet, a second light enhancing sheet and preferably, an upper diffusion sheet are installed between the sub-display screen and the light guide plate. Part of light from the sub-display screen is reflected to the main display screen.

Abstract: A direct type backlight modulus lamp replacement device with each lamp respectively being fixed in a replacement device, the replacement device being provided at the bottom of the lampshade in relation to a slot of the lamp, a recess being formed in the device to place the lamp, a positioning part being each extended from both sides of the recess to secure the device at the bottom of the lampshade so to replace the lamp only by removing it from the lampshade without removing the entire reflection lampshade.
