摘要:
A backlight assembly and a liquid crystal display device can discharge heat from the lamp unit to the outside or effectively dissipate the heat. The backlight assembly of the present invention includes a lamp unit, a receiving member for receiving the lamp unit, a first heat dissipation member disposed below the receiving member, and a second heat dissipation for wrapping around a lateral side of the receiving member and the first heat dissipation member. The lamp unit is disposed on an area corresponding to the lateral side of the receiving member. In one embodiment, the first heat dissipation member is a flat plate made of graphite and disposed on an outer side of the bottom of the receiving member. The second heat dissipation member is metal with good thermal conductivity in close contact with the first heat dissipation member and the lateral side of the receiving member where the lamp unit is disposed. Thus, the heat discharged from the lamp unit can be distributed uniformly over the entire area of the receiving member. In addition, the lateral side of the receiving member where the lamp unit is disposed can be replaced with the second heat dissipation member.

A surface treatment method of an FRP substrate is provided. According to the method, an FRP substrate that is less deformed than a conventional flexible substrate material is used, and surface roughness, which is a drawback of the FRP substrate, is improved so that it may be applied to the fabrication of a device. In order to reduce the surface roughness of an FRP substrate, the FRP substrate is coated with an organic insulating solution and thereby planarized. Due to the reduced deformation and superior flatness, failures occurring due to misalignment in a photolithography process may be prevented.

The present invention relates to an ultrasound imaging apparatus having a function of selecting transmit focal points and method thereof, in which an operator may select at least one transmit focal point, allowing for transmit-focusing ultrasound signals upon the selected focal point to create an ultrasound image of a target object. The ultrasound imaging apparatus includes an ultrasound transducer array, a pulse generator, a controller, a database, an input device, an analog-to-digital converter (ADC), a beam former, a signal processor, and a display device. The method for ultrasound imaging comprises the steps of: a) transmitting to a target object ultrasound signals in accordance with a predetermined initial time-delay profile; b) receiving and processing the reflected ultrasound signals from the target object to create an ultrasound image of the target object; c) displaying the created ultrasound image to allow an operator to select at least one region of interest within the displayed ultrasound image; d) in response to the operator's selection, detecting coordinates of the selected region of interest; e) determining at least one transmit focal point corresponding to the detected coordinates of the selected region of interest; f) determining at least one new time-delay profile based on each of the transmit focal points; and g) transmitting the ultrasound signals in accordance with the new time-delay profile to the target object; h) receiving and processing the reflected ultrasound signals off the target object to create an updated ultrasound image of the target object.
