摘要:
A back light module for a liquid crystal display. The module has a rear cover, a reflective film and a high-reflective mode frame. The rear cover has a bottom plate and a side plate; a first side of the side plate is connected to a side of the bottom plate. The reflective film is disposed on a top surface of the bottom plate and an internal side surface, so as to replace a lamp reflector. The high-reflective mode frame is put on the second side, which is opposite the first side of the side plate.

A liquid crystal display device comprises a liquid crystal panel having two substrates and a liquid crystal material sealed therebetween; a backlight module disposed under the liquid crystal panel; and a display case for housing the liquid crystal panel and the backlight module. The backlight module is a direct point-light type and comprises a plurality of point light sources, a reflector, a diffuser and a plurality of optical sheets. The reflector has a plurality of openings respectively positioned in relation to the point light sources such that the light provided by the point light sources can pass through the openings of the reflector and then reach the diffuser. The diffuser has a plurality of dot elements which are formed thereon and compose at least one of radially variable dot specific pattern. The radially variable dot specific pattern defines a center portion, and at least one of the point light sources is aligned relative to the center portion of the radially random dot specific pattern.

A liquid crystal display panel mainly includes a first substrate, a second substrate, a liquid crystal layer sandwiched between the first and the second substrates, and a plurality of first protrusion disposed on the first substrate for maintaining a first cell gap between the first and second substrates. The present invention is characterized by having a plurality of second protrusions disposed on the first substrate for maintaining a second cell gap smaller than the first cell gap when the liquid crystal display panel is subjected to an external force. But when the liquid crystal display panel isn't subjected to any external force, the second protrusion is separated from the second substrate by a distance. The present invention further provides a method for manufacturing the liquid crystal display panel.

A liquid crystal display device mainly includes a first substrate, a second substrate, and a liquid crystal layer sandwiched between the first and the second substrates. The first substrate is attached to the second substrate by a radiation-cured sealant. The first substrate is provided with a light-shielding frame around the display area, wherein the frame forms the corners into a nonrectangular shape and superposes over a substantial portion of the sealant.

A common line is eliminated, and one terminal of the capacitor, which has been heretofore connected to the common line, is connected to the scan line of another display cell adjacent to the display cell having the capacitor. A scan line driving circuit supplies to respective scan lines a stepped pulse formed of a voltage V1 and a voltage V2 sufficiently larger than the voltage V1. A data line driving circuit supplies to the respective data lines a voltage not smaller than the voltage V1 and not larger than a voltage V3 (but smaller than the voltage V2) as a data voltage.

An illuminating device mainly includes a tube-like lamp disposed in a main body. The tube-like lamp has two terminal portions adapted for electrically connecting to a power source and a bending portion between the terminal portions. The main body is provided with a support having two hooked portions configured to support the tube-like lamp. The present invention further provides another tube-like lamp characterized by having a buffer part securely attached on the bending portion for lessening or absorbing the shock of an impact on the tube-like lamp. The support may has a gap between the hooked portions such that the tube-like lamp fit with sufficient tightness into the gap between the hooked portions thereby immobilizing the tube-like lamp more efficiently and absorbing the shock.

A surface wire that is connected to a scan line and the other surface wire that is connected to the other scan line via a thin-film transistor are arranged with a distance of at least 5 nullm between these surface wires. Based on this structure, it is possible to prevent a current conduction between these surface wires due to impurity ions that is adhered to the surface wire while the power source is ON and that spreads while the power source is OFF. By suppressing a current leakage, it is possible to suppress the degradation of the screen display characteristics such as a color blur.

The present invention relates to an assembling structure of a metal frame and an electric module for use in a liquid crystal display. The metal frame comprises an inside portion and a straight portion. The inside portion has a plurality of holes formed on a side of the metal frame. The electric module comprises a circuit board and at least one straight strip. The straight strip is mounted on a side of the circuit board. The straight strip has a plurality of hooks formed in positions corresponding to the holes. The hooks are adapted to be accommodated in the holes so as to assemble the electric module on the metal frame. Therefore, according to the invention, the electric module can be assembled easily on the metal frame. The grounding of the electric module electrically connects to the metal frame. The grounding characteristic of the electric module is good, and the circuits of the electric module work stably., Furthermore, it is easy to separate the electric module from the metal frame without breaking the electric module and the metal frame. After the electric module is separated from the metal frame, the electric module and the metal frame can be reused. Therefore, the total cost is decreased.
