The liquid crystal display and backlight module of the component. [Prior Art] Liquid crystal displays have flourished in small-sized or large-sized applications, and since liquid crystal displays have light weight, thin size, low power consumption, no radiation, and other excellent characteristics, they have become on the market. Mainstream products. Therefore, liquid crystal displays have been widely used in various information products, such as notebook computers, mobile phones, digital cameras or personal digital assistants (PDAs), and even gradually replace the traditional cathode ray tube (CRT) TV, back. Projection TV or plasma display panel (PDP) TV. Since the liquid crystal molecules themselves do not emit light, the back thinning becomes one of the main components of the liquid crystal display, and the conventional backlight module utilizes a cold cathode fluorescent lamp ((7) w eathodefluorcscenUamp ' CCFL) as a light source. FIG. 1 is a partial cross-sectional view of a conventional backlight module. The backlight module 1 〇 includes a light guide plate, a cold cathode fluorescent lamp tube 12 disposed near the light guide plate 14, and a light guide plate disposed under the light guide plate. The second plate 16, the plurality of optical films 18 disposed on the light guide plate 14, and a frame 20 for fixing the assembly of the backlight module 10. Since the cold cathode fluorescent lamp 12 generates light from each side of the tube Therefore, it is necessary to place a lamp anti-1357525 reticle 22 beside the cold cathode fluorescent lamp tube 12 to reflect the light back to the cold cathode fluorescent lamp tube 12 or the light guide plate 14, thereby improving light utilization efficiency and, in order to avoid The light is leaked from the upper side gap between the bulb reflector 22 and the optical web 18, and a light-shielding tape 24 is provided to shield the gap between the bulb reflector 22 and the optical film 18. However, due to the cold cathode fluorescent lamp The liquid crystal display with the tube as the light source limits the improvement of the color specification, so the light source of the cold cathode fluorescent tube has gradually failed to meet the needs of the customer, and the cold cathode fluorescent tube itself contains mercury, which does not meet the requirements as a green product. .therefore' In the past few years, light emitting diodes (LEDs) have been used as light sources in backlight modules because of their high color saturation, fast response rate and small size, making them small in size. Liquid crystal displays are popular. However, due to the immature white light technology emitted by white light-emitting diodes, red, green and blue light-emitting diodes are used in backlight modules in many products. In this case, in order to fully mix the red φ light, the green light and the blue light, it is necessary to have a good light mixing design, so the light-emitting one-lamp backlight module requires a complicated mechanical structure and is higher than The price of a cold cathode fluorescent tube backlight module is disclosed in US Patent No. 6,930,737 and US Patent Publication No. 2005-0157521, the entire disclosure of which is incorporated herein by reference.

One of the outer sides 115 of the strip 114 is not obscured by the frame wall ii6c, that is, the outside of the strip 114 is exposed to the frame 116. Since the light bar 114 is inserted into the frame wall 116c and adjacent to the compartment 116b provided with the light guide plate 1〇8, the light emitting surface of the light emitting diode 1丨2 is relatively close to the light guide plate 108, so that the light emitting diode 112 emits φ. The emitted light directly penetrates the side wall of the light guide plate 108 to provide a planar light source. In addition, according to the 7th and 7th diagrams, regardless of the X-axis or the γ-axis of the light-emitting diode 112, the relative luminous intensity of the light-emitting diode 112 having an emission angle of more than 80 degrees is almost zero, and the emission angle is greater than 60 degrees. The relative luminous intensity of the diode 112 is less than 5 〇 β. Therefore, the side-type light-emitting diode 112 applied to the present invention has a scattering angle of about ±80 degrees, preferably about ±6 degrees. This means that the total scattering angle of each of the light-emitting diodes 112 is 120 degrees. Therefore, since the light-emitting diode 112 has a directivity characteristic, the lamp reflector used in the prior art is no longer necessary for the present invention. Moreover, when the scattering angle is not large, the extra light-shielding tape in the conventional backlight module can be ignored because the large-angle light emitted by the light-emitting diode 112 is very small. Moreover, even if the light emitted by the illuminating body 112 has a large sinusoidal scatter, the light does not penetrate directly into the light guide plate 108. The frame 116 can block the light and prevent the light from being emitted from the backlight module. . For example, if the frame 116 is made of a white material, the light that travels to the frame 116 above the LED 112 will be reflected back to the light guide plate, thereby increasing the light paste rate; otherwise, if the frame 116 A frame 116 made of a black material that breaks into the light-emitting diode 112. The light is absorbed by the frame 116, thus avoiding the problem of tilting. It can be seen that the device of the present invention does not require the lamp freshening or viewing tape outside the 1357525, and the group inspection process is also simplified, which can save raw materials. Please refer to pictures 8 and 9. Figures 8 and 9 show a partial enlarged view of the backlight module 1〇4. Fig. 8 is the back side of the backlight module 1〇4, wherein the reflection sheet 122 is disposed in the compartment 116b of the frame 116. The screw 124 is used to fix the light bar 114 in the light bar accommodating space 120, and is detached from the back surface through the screw hole in the frame II6. In addition, it is worth noting that the opening 116d includes two narrow portions and a wide portion 12 interposed between the narrow portions 120a. In order to accommodate the light bar 114, the height h of the narrow plate is close to or slightly larger than the printing. The thickness of the circuit board 11 is, and the height Η of the wide portion i2〇b is close to or slightly larger than the total thickness of the printed circuit board 11 〇 and the light emitting diode 112. " On the other hand, Fig. 9 is the front side of the backlight module 104. In various embodiments, the screw 132 can be secured to the light strip 114 by the front surface of the backlight module 1〇4 through the screw holes 13 of the frame 116. Therefore, a screw hole 126 can be provided on the printed circuit board 11 for bucking the screw 132. In addition, since the light strip 114 is a plug-and-play light strip, 'therefore, it includes at least one conductive pad 128 disposed on the printed circuit board 110. Therefore, when the light strip 114 is inserted into the light strip accommodating space 12, it is electrically conductive. The pad 128 is electrically connected to a wire (not shown) which may be disposed in the frame 116 or electrically connected to a flexible printed circuit (not shown). 10 to 14 are partial views of a backlight module 〇4 according to various embodiments of the present invention. For the sake of simplicity, most of the elements have the same reference numerals as those of the elements shown in Figs. Please refer to the 1() chart. The first drawing is a second embodiment of the present invention. The frame wall 116e of the frame 116 has an opening l16d' in which the frame wall 1 is detached to form the light strip accommodating space 136, and the opening 116d includes a plurality of narrow portions 14A and a plurality of wide portions 138. In order to accommodate the light bar 114, the height h of the narrow portion 14A is close to or slightly larger than the thickness of the printed circuit board no of the light bar 114, and the height H of the wide portion 138 is close to or slightly larger than the printed circuit board 110 and one light emitting diode. The total thickness of the body 112. Therefore, when the light bar 114 is inserted into the light strip accommodating space 136, the light strip 114 is firmly fixed without horizontal traverse. Further, the width of the wide portion 138 is close to or slightly larger than the width of the light emitting diode 112. Please refer to Figure 11. 11 is a schematic view of a frame 116 and a light bar 148 of a backlight module 104 according to a third embodiment of the present invention. In this embodiment, the plug-and-play light strip 148 includes a printed circuit board 144 and a plurality of light-emitting diodes 146 disposed on the printed circuit board 144, wherein the printed circuit board 144 has at least one wide face 144a parallel to The light guide plate disposed in the compartment 116b is parallel to the frame wall 116c with at least one narrow face 144b. It should be noted that the light-emitting diodes 146 are placed on the narrow faces 144b, so the total thickness of the light bars 148 is smaller than in the previous embodiment. Therefore, the height of the opening 142 on the frame wall 116c can be relatively small, almost the same as the thickness of the printed circuit board 144, that is, the height of the opening 142 is equal to or greater than the thickness of the light bar 148. 12 and 13 are schematic views of the frame 116 1357525 and the light bar 156 of the backlight module 104 according to the fourth embodiment of the present invention. This embodiment utilizes a top type light emitting diode 152 to form a light strip 156. The plug-and-play light strip 156 includes a printed circuit board 150 for accommodating the light-emitting diodes 152, and the printed circuit board 150 has two wide faces 15a and two narrow faces 150b. Since the light-emitting diode 152 is of a top type, the light-emitting body 152 can be placed on the wide surface 150a of the printed circuit board 150 facing the light guide plate 1〇8. Therefore, as shown in Fig. 13, when the light bar 156 is inserted into the light strip accommodating space 154 ^, the wide surface 150a of the non-light emitting diode is placed parallel to the frame wall ii6c, and the light strip accommodating space 154 The height is almost the same as the width of the wide face i5〇a of the printed circuit board 150. And in order to fix the light bar 156 in the light strip accommodating space 154, the printed circuit board 150 may be adhered to the frame wall 116c by a plurality of narrow tapes 160 or a wide tape (not shown). Figure 14 is a schematic view showing a frame 116 and a light bar 114 of a backlight module according to a fifth embodiment of the present invention. The light strip 114 used in this embodiment is the same as the first embodiment of the present invention. The light strip 114 includes a printed circuit board 110, a plurality of side-type LEDs 112, a screw hole or a The positioning hole 126 and a conductive pad 128 placed on the printed circuit board 110. It is worth noting that the frame forming the light strip accommodating space • The opening 158 of the U6 is a one-piece opening. The height of the opening 158 is close to or slightly larger than the total thickness of the printed circuit board 110 and one of the light emitting diodes 112. An advantage of the present invention is that the strip of light that is ready to use is placed in the light-receiving space' so that additional light-shielding tape or tube reflectors of the prior art are no longer needed. Furthermore, the light source is a plug-and-play type light source and the frame of the backlight module is a 13 1357525 integrally formed structure. Therefore, the material of the frame can be reduced, and it is very easy to assemble the backlight module by inserting the plug-and-play light strip into the space of the light bar, so that the manpower for assembling the backlight module can be saved. In addition, since the light strip is inserted into the frame wall of the frame, the entire backlight module can thus have a narrow side for arranging the light source. On the other hand, because the light strip inserted into the wall of the frame is placed almost adjacent to the light guide plate, the light from the light source can directly penetrate into the light guide plate and less light is lost. In view of the above, the liquid crystal display or the backlight module of the present invention has at least the advantages of reduction, reduction, space saving, and high light transmittance. Therefore, according to the present invention, a liquid crystal display and a backlight module having a simple structure and good efficiency can be provided. The above description is only a preferred embodiment of the present invention, and all the scales modified according to the patent application of the present invention are covered by the scope of (4).
