Description

1361303 九、發明說明: 【發明所屬之技術領域】 本發明係關於一種背光模組,尤指該背光模組中提供 導光板、發光組件以及光學膜片置設其中,且具有定位光 學膜片功能之框座設計。 -【先前技術】 目前應用於筆記型電腦或液晶顯示器、…電子產品, 須藉助背光模組提供背光源輔助畫面的顯示用途。所述之1361303 IX. Description of the Invention: [Technical Field] The present invention relates to a backlight module, and more particularly to providing a light guide plate, a light-emitting component, and an optical film disposed therein, and having the function of positioning an optical film The frame design. - [Prior Art] Currently used in notebook computers or LCD monitors, ... electronic products, the backlight module is required to provide the display of the backlight auxiliary screen. Said

背光模組之組成,主要係於框座中裝設中背面具有反射膜 片的導光板、以及一發光組件位於該導光板側面,並於該 導光板前面設置至少-光學膜片’藉此,利用發光組件發 光投射於該導光板一側的入光面,並透過導光板内部之折 射作用、以及背面反射膜片對光之反射作用,使光自導光 板前面射出,並透過光學膜片而均勻散射,用以對液晶面 板提供均勻的背光源。 前述之背光模組中,如第七圖所示,為使光學膜片 0 )穩固地定位於框座(3 〇)内,即令該光學膜片(4 0 )側邊凸伸至少—凸部(4 1 ),於該框座(3 〇 )之 堤牆上形成相對應之定位凹部,提供該凸部(4丄)對位 伸入其中’再以膠帶(5〇)將該㈣(4ι)黏著固定 於框座(30)之堤牆上,使光學膜片(4〇)固定於框 座(3 0 )中。 式 惟前揭使用膠帶將光學膜片固定於框座中之作業方 因須依據光學膜片之凸部所在位置’再切帶精確貼 4The backlight module is mainly composed of a light guide plate having a reflective film on the back side of the frame, and a light-emitting component on the side of the light guide plate, and at least an optical film is disposed in front of the light guide plate. The light-emitting component emits light on the light-incident surface of the light-guide plate, transmits the light inside the light-guide plate, and reflects the light from the back-reflecting film, so that the light is emitted from the front surface of the light guide plate and transmitted through the optical film. Uniform scattering to provide a uniform backlight to the LCD panel. In the foregoing backlight module, as shown in the seventh figure, in order to firmly position the optical film 0) in the frame (3 〇), the side of the optical film (40) protrudes at least—the convex portion (4 1 ), a corresponding positioning recess is formed on the wall of the frame (3 〇), and the convex portion (4丄) is provided to extend into the position, and then the tape is placed (5 〇) (4) (4) Adhesively fixed to the wall of the frame (30) to fix the optical film (4〇) in the frame (30). Only the work of fixing the optical film in the frame with tape is required to be based on the position of the convex portion of the optical film.
