Description
Technical field
The present invention relates to a kind of backlight assembly (backlight moldule), and particularly relates to a kind of backlight assembly with heat dissipation design.
Background technology
Along with LCD (liquid crystal display, LCD) manufacturing technology develops fast, with and possess advantages such as frivolous, power saving and radiationless line arranged, make LCD be applied in large quantities personal digital aid (PDA) (personal digital assistant, PDA), in the various electronic product such as mobile computer, digital camera, digital camera camera, mobile phone, computer screen and LCD TV.Add the positive input research and development of industry and adopt the production equipment that maximizes, the quality of LCD is improved constantly, and the lasting decline of price, therefore make the application of LCD enlarge rapidly.But, need could produce the function that shows by the light that backlight assembly provided because the display panels in the LCD is the display panel of non-self-luminosity.
With reference to Figure 1A and Figure 1B, Figure 1A is the part vertical view of the traditional backlight assembly of expression simultaneously, and Figure 1B is the front view of the backlight assembly of expression Figure 1A.In Figure 1A and Figure 1B, backlight assembly 10 comprises cold-cathode tube (cold cathodefluorescent lamp, CCFL) 16 of a framework 12, reflector plate 14 and several straight pipe types at least.Framework 12 comprises a body 12a, one first support portion 12b and one second support portion 12c, and body 12a has a body end face 12d.The first support portion 12b and the second support portion 12c are arranged on the two ends of body end face 12d, and the top of the first support portion 12b and the second support portion 12c has several grooves 17b and 17c respectively.Reflector plate 14 is arranged on the body end face 12d, and between the first support portion 12b and the second support portion 12c.It should be noted that on the inner surface of the first support portion 12b that is connected with body end face 12d and the second support portion 12c and also other reflecting material can be set.Each cold-cathode tube 16 is to comprise an illuminating part 16a and electrode part 16b and 16c, and illuminating part 16a is 16b of connection electrode portion and 16c.When among the groove 17c of the groove 17b that the electrode part 16b and the 16c of all cold-cathode tubes 16 are placed in the first support portion 12b respectively and the second support portion 12c, cold-cathode tube 16 is arranged on the framework 12 in the mode of the top that is positioned at reflector plate 14.
When electrode part 16b and 16c were applied in a high voltage, electronics was promptly penetrated toward illuminating part 16a by electrode part 16b and 16c, and electronics will with the mercury bump in the illuminating part 16a.After the electron impact that mercury is quickened by high voltage, mercury will return a steady state (SS) rapidly by a non-steady state, and with excess energy with wavelength be 253.7 how the ultraviolet ray of rice (nm) discharge.This ultraviolet ray will be absorbed by the fluorescent powder of the inwall of illuminating part 16a and transfer visible light to, to penetrate to the fluorescent tube of cold-cathode tube 16.
It should be noted that cold-cathode tube 16 will produce heat when cold-cathode tube 16 is luminous, the pipe surface temperature of cold-cathode tube 16 will raise.Because mercury is easier to assemble at low temperature time ratio, but cold-cathode tube 16 pipe surface temperatures are more and more higher, mercury is not easy to accumulate in illuminating part 16a more, causes mercury to spread toward electrode part 16b and 16c.Mercury will be deposited on electrode part 16b and 16c because of splash effect (sputter effect), and the electrical quality that influences electrode part 16b and 16c is very big.Thus, the life-span of cold-cathode tube 16 will shorten, and the brightness quality of backlight assembly 10 is also with variation.
