Abstract
A portable display device capable of preventing the ambient temperature of a light source provided in a liquid crystal display device from being intensively raised. The portable display device is constructed with a liquid crystal display panel; a backlight assembly including light source for supplying light to the liquid crystal display panel, and a mold frame receiving the liquid crystal display panel and the light source as well as surrounding at least two sides of the light source. At least one region of the mold frame surrounding the sides of the light source is formed of at least one aperture.
Claims10
A portable display device, comprising:
- a liquid crystal display panel;
- a backlight assembly comprising a light source for supplying light to the liquid crystal display panel;
- and
- a mold frame included in the backlight assembly and retentively receiving the liquid crystal display panel and the light source as well as surrounding at least two sides of the light source, with at least one region of the mold frame surrounding the sides of the light source perforated by at least one aperture , and air in a first space formed between the light source and the mold frame being convectively connected via said aperture to ambient air in a second space which is external to the first space.
A method for dissipating heat generated by a portable display device comprising a liquid crystal display panel, a backlight assembly comprising a light source for supplying light to the liquid crystal display panel, a mold frame receiving the liquid crystal display panel and the light source and surrounding at least two sides of the light source, the method comprising:
- forming at least one aperture in at least one region of the mold frame surrounding the sides of the light source in such a way that the air between the light source and the mold frame can be transferred to a space which is external with respect to the space between the light source and the mold frame;
- and
- controlling the cross-sectional area and the length of the aperture to control a rate of heat transfer of the air between the light source and the mold frame and the air in the space which is external with respect to the space between the light source and the mold frame.
