[Prior Art] [0002] In order to overcome the problem that the user cannot recognize and use the keyboard in a low-brightness or dark environment, the keys used in electronic devices such as desktop computers, tape-type computers, and mobile phones are installed inside. A lighting module is provided to allow the user to see the character symbols on the keyboard and to facilitate typing on the keyboard. [0003] Generally speaking, the light-emitting module is disposed under the keyboard, and emits light toward the keyboard to illuminate the keyboard; however, the light of the light-emitting module overflows between adjacent two keycaps to form interference light. And the user is unable to effectively recognize the character symbol located on the keycap. [0004] In order to solve the above problem, most manufacturers install a light shielding film between the light emitting module and the keyboard, and the light shielding film is formed with a plurality of light transmitting regions corresponding to the key caps, and preferably ' The light shielding sheet faces the side of the light emitting module to be black or other color having better light absorbing ability. The visor absorbs light that is not transmitted to the light-transmitting regions, so as to prevent light from the illuminating module from overflowing between adjacent two-key caps. In this way, although light can be effectively prevented from being transmitted from the adjacent two-key caps, except for the light transmitted to the key caps through the light-transmitting regions, other portions of the light are blocked by the light-shielding film. Absorption' causes the overall light to be used very inefficiently. 10120002#单号A0101 Page 3/20 pages 1012000075-0 M429135 [New content] [0005] In view of the prior art, one of the purposes of the present invention is to provide an input device that can effectively improve light.

The light guide plate 134 may be in the form of a flat plate or a wedge plate, and may be a single plate or a plurality of light guide plates 134 formed into a large plate body. In the embodiment, the light guide plate 134 is guided by a single light. The light source 132 is disposed on one side of the light guide plate 134 and emits light toward the light guide plate 134. In this embodiment, the light source 132 is disposed on one side 135 of the width direction of the light guide plate 134 and faces The side 135 emits light, The light source 132 can be disposed on one side 135 of the length direction of the light guide plate 134. Alternatively, the light source 132 can be disposed under the light guide plate 134 to form a direct-lit light. The light source 132 may be embedded in the light guide plate 134. The light source 132 may be a light emitting diode, a small light bulb or a light tube (such as a cold cathode light tube), and the number thereof may be one or more.

And the size of the optical film 140 The size of the optical module 140 is at least greater than the circumference of the light-emitting module 130. 0.5 mm (mili me ter) 'to avoid the light by the light 10120002# single number A〇101 Page 6 of 20 1012000075-0 M429135 The periphery of the film 140 is revealed and transmitted to the keyboard module 120. [0014] The optical film 140 has a plurality of light transmissive regions 142, and the light transmissive regions 142 The pair of button units 122 are arranged such that the light emitted by the light-emitting module 130 correspondingly illuminates the button units 122 after passing through the light-transmitting regions 142, and avoids light from the adjacent two-button units 122. The gap between the openings is transparent, wherein the light transmitting region 142 can be an opening or a light transmitting layer. [0015] The optical film 140 further includes a light-shielding layer 144 and a light-reflecting layer 146. The light-shielding layer 144 is disposed above the light-reflecting layer 146.

The color of the light-shielding layer 144 can be adjusted according to actual needs or limitations. The light-reflecting layer 146 is disposed adjacent to the light-emitting module 130, and the light-reflecting layer 146 can be disposed. The color of the reflective layer 146 can be adjusted according to actual needs or limitations when it is implemented in a white or silver color. The light-reflecting layer 146 can be directly disposed on the light-shielding layer 144 by a coating process. The light-shielding layer 144 can also be directly disposed on the light-reflecting layer 146 by a coating process. . The light reflecting layer 146 reflects a portion of the light transmitted by the light emitting module 130 toward the keyboard module 120 but not passing through the transparent region 142, so that the portion of the light can be re-entered into the light guide plate 134. The light-shielding layer 144 absorbs a small portion of the light that penetrates the light-reflecting layer 146 to prevent the light from being transmitted through the gap between the adjacent two button units 122 to cause the user to recognize the button units 122. Difficulties. [0017] Referring to the fifth and sixth figures, respectively, an exploded perspective view, a cross-sectional view and a partial enlarged view of the input device of the second embodiment of the present invention are shown. The input 1012000075-0 single number A0101 page 7 / 20 pages M429135 device is similar to the first embodiment described above, except that its optical film 140a further includes a bending section 141a, which The bending section 141a is formed on the periphery of the optical film 140a and covers the light emitting module 130 to avoid light overflow and improve light use efficiency. The optical film 140a further includes a light shielding layer 144a adjacent to the keyboard module 120 and a light reflecting layer 146a adjacent to the light emitting module 130. The light reflecting layer 144a reflects light that does not pass through the plurality of light transmitting regions 142a. Re-entering the light guide plate 134 is provided to increase the efficiency of use of the overall light. The light shielding layer 144a absorbs light that partially penetrates the light reflecting layer 144a to prevent light from being transmitted through the slits between the adjacent two button units 122 to form interference light. [0018] Referring to the seventh figure, a partial cross-sectional view of the input device of the third embodiment of the present invention is shown. The input device of this embodiment is substantially similar to the first embodiment described above, except that the light shielding layer 144b further includes an adhesive member 148, and the adhesive member 148 is coupled to the light shielding layer 144 and the reflective layer. 146, wherein the light shielding layer 144 and the light reflecting layer 146 are preferably thin diaphragms. The adhesive member 148 may be glue or double-sided tape. The adhesive member may also be disposed on the reflective layer 146 during actual implementation. [0019] Further, the input device 10b further includes a reflective sheet 150 disposed between the bottom plate 11 () and the light emitting module 13A for reflecting the light emitting module 130 toward the The light that overflows in the direction of the bottom plate 110 increases the overall light use efficiency. [0020] Referring to the eighth embodiment, a partial cross-sectional view of the input device of the fourth embodiment of the present invention is shown. The input device is similar to the first embodiment described above, except that the optical film 140c further includes a light transmissive layer 149. The light transmissive layer 149 may be transparent or at least translucent. 10120002# The single number A0101 is 8th/20 pages 1012000075-0 M429135 and is disposed between the light shielding layer 144 and the light reflecting layer 146. Moreover, the light transmissive layer 149 has a plurality of microstructures 144 at the corresponding light-transmitting regions 142. The microstructures 1490 are used to guide the light passing therethrough so that the light can be correspondingly projected to the button units 122. . [0021] In summary, the reflective layer of the optical film of the input device of the present invention can effectively reflect the light emitted from the light emitting module toward the keyboard module but cannot be transmitted from the light transmitting region to the button units. The light is redirected to the light-emitting module to provide overall light efficiency; further, the light-shielding layer can absorb light that partially penetrates the light-reflecting layer to prevent light from overflowing between adjacent two-button units. However, it is difficult to identify the button units. [0022] However, the above descriptions are only preferred embodiments of the present invention, and the scope of the present invention cannot be limited, that is, the equal changes and modifications made by the scope of the patent application of the present invention should still belong to the present creation. The scope of the patent coverage is intended to be protected.
