Description
Technical field
The present invention is about a kind of flat-panel screens, particularly about a kind of LCD.
Background technology
Along with information, communications industry are constantly weeded out the old and bring forth the new, driven LCD (liquid crystaldisplay; LCD) market is flourish.LCD has that high image quality, volume are little, in light weight, low driving voltage, with advantage such as low consumpting power, therefore be widely used in personal digital assistant (personaldigital assistant; PDA), mobile phone, shoot with video-corder projector, notebook, desktop display, automobile-used display, and consumer communication or electronic product such as projection TV.Add integrated circuit (integrated circuit; IC) advancing by leaps and bounds of industry and LCD manufacturing technology, these consumer communications or electronic product are also towards light, thin, short, little trend development.Especially aspect computer product, except high-performance, high-speed desktop PC, notebook easy to carry is subjected to noting greatly and paying attention to especially.
Traditionally, the small size LCD MODULE all is fixed in liquid crystal panel and backlight module in one module frame.And utilize flexible printed wiring board (Flexible Printed Circuit Board; FPC) flexible characteristic is connected the one end with liquid crystal panel, the other end then reflexed in the rear of module frame.And light emitting diode (light emitting diode; LED) the backlight module light emitting source that is constituted then utilizes another flexible circuit board to be installed among the framework, so that light source to be provided.The flexible circuit board of this LED utilizes modes such as welding or connector again, and it is connected with the system's flexible circuit board that is connected liquid crystal panel (Main Flex).Consult Fig. 4 and illustrate two flexible circuit boards and utilize welding manner to link, then again along the rear of direction of arrow reflexed in module frame.
In addition, traditional LCD MODULE of part then is disposed at led light source on system's flexible circuit board simultaneously, and stick in the rear of framework with this flexible circuit board reflexed and with adhesive tape, with the fixed system flexible circuit board, and with the led light source folding in the display module back side.Consult Fig. 5 and illustrate a traditional flexible circuit board, its along the direction of arrow by reflexed and stick in the rear of framework.
No matter be to utilize single flexible circuit board or utilize two independently small-sized LCD MODULE of flexible circuit board, because behind the flexible circuit board reflexed and attach to the rear of framework, therefore the thickness of module will be increased, and then the gross thickness of the electronic installation of using this LCD MODULE is increased, be unfavorable for the miniaturization of electronic installation.
In addition, the connection of two independent flexible circuit boards then more increases costs such as connector or welding, has also therefore increased the manufacturing cost of LCD MODULE.And single flexible circuit board reflexed and attach to the rear of module, then usually because the screen resilience of flexible circuit board and perk cause dial from so that make the LED offset, and then cause the optics briliancy seriously to be offset.
Therefore, how the apparent size and the manufacturing cost of small-sized plane display device can effectively reduced, and provide the fixed sturcture of a kind of coupling system flexible circuit board and LED flexible circuit board to be looked forward to by each side.
Summary of the invention
In the explanation of above-mentioned prior art, the fixed form of traditional flexible printed wiring board will cause the thickness of flat-panel screens to increase, and more likely because the skew of LED position, and cause serious optics briliancy skew.Therefore, the flexible circuit board of fixed pan display how effectively, the further thickness of reduced plan display not only can also effectively improve the quality of flat-panel screens, reduces the production cost of flat-panel screens simultaneously.
Therefore, one of purpose of the present invention provides a kind of flat display apparatus, with the flexible circuit board folding between framework and display panel, with the thickness of effective reduction flat display apparatus.
Another object of the present invention provides a kind of flat display apparatus, and the flexible circuit board folding between framework and display panel, with the risk of effectively avoiding flexible circuit board to peel off, and then is improved the phenomenon that the optics briliancy is offset.
Another purpose of the present invention provides a kind of flat display apparatus, to dispose the flexible circuit board folding of light emitting diode and display panel, drive circuit between framework and display panel, improve the alignment precision of light emitting diode and leaded light component, therefore, can not only simplify the assembling manufacture craft of flat display apparatus, improve the quality of flat-panel screens simultaneously.
According to above-mentioned purpose, the present invention proposes a kind of flat display apparatus, has a framework, a display panel and a flexible circuit board.Display panel is arranged on the framework.Flexible circuit board has the driving circuit of luminescence component and display panel, and the one end is connected in display panel, and then reflexed is in the rear of display panel for the other end, and therefore, luminescence component and display panel, drive circuit are placed between framework and the display panel.This flat display apparatus also includes a leaded light component and is installed among the framework, make luminescence component via leaded light component to illuminate display panel.Wherein, leaded light component disposes between framework and display panel, and luminescence component is aimed at a light inlet of leaded light component.
After among leaded light component is installed on framework, framework and leaded light component form a groove, with ccontaining luminescence component and display panel, drive circuit.Wherein display panel is preferably a display panels, and luminescence component is preferably a light emitting diode.This flat display apparatus preferably is applied on the mobile phone, and flexible circuit board comprises that also a link is to electrically connect a master control circuit board of mobile phone.And also include one grade of wall around the framework, with ccontaining display panel, flexible circuit board and leaded light component.
Therefore, flat display apparatus of the present invention, ease of assembly not only reduces the thickness of flat display apparatus simultaneously, can also guarantee the alignment precision of light emitting diode and leaded light component, effectively reduces manufacturing cost and promotes the quality of product.Simultaneously, the risk that can also effectively avoid flexible circuit board to peel off makes that the apparent size of flat display apparatus is more accurate, and is easier to assembling.
