Description
本發明涉及一種訊號顯示器，尤其係涉及一種用於攜帶型電子裝置之訊號顯示器。 The present invention relates to a signal display, and more particularly to a signal display for a portable electronic device.
隨著移動通訊技術之發展，行動電話及個人數位助理(Personal Digital Assistant,PDA)等攜帶型電子裝置已逐漸成為人們日常生活之必需品。 With the development of mobile communication technology, mobile electronic devices such as mobile phones and personal digital assistants (PDAs) have gradually become a necessity in daily life.
攜帶型電子裝置往往藉由設置一訊號顯示器以顯示該攜帶型電子裝置之工作狀況，如來電狀況顯示、未接來電狀況顯示及短訊息狀況顯示等。習知之訊號顯示器通常包括複數側發光二極體(Light-Emitting Diode,LED)及一導光板，該側發光二極體設置於導光板之端部，其發出之光線藉由該導光板之傳導及反射作用傳送至所需顯示之圖標，從而照亮該圖標而達到顯示攜帶型電子裝置工作狀況之目的。 The portable electronic device often displays a signal display to display the working status of the portable electronic device, such as an incoming call status display, a missed call status display, and a short message status display. The conventional signal display usually includes a plurality of light-emitting diodes (LEDs) and a light guide plate. The side light-emitting diodes are disposed at the ends of the light guide plates, and the emitted light is transmitted by the light guide plates. And the reflection effect is transmitted to the icon of the desired display, thereby illuminating the icon to achieve the purpose of displaying the working condition of the portable electronic device.
惟，由於側發光二極體價格較昂貴，導光板之製造成本亦較高，造成訊號顯示器整體生產成本提升，另，採用上述結構之訊號顯示器之側發光二極體發出之光線使用率較低，需增加側發光二極體之電流量來滿足整個訊號顯示器之亮度需求，如此則又增加了側發光二極體之耗電量及使用壽命。 However, due to the relatively high price of the side-emitting diodes, the manufacturing cost of the light guide plate is also high, resulting in an increase in the overall production cost of the signal display. In addition, the light-emitting diodes using the signal display of the above structure emit light with a lower light utilization rate. The amount of current of the side-emitting diode needs to be increased to meet the brightness requirement of the entire signal display, which increases the power consumption and service life of the side-emitting diode.
有鑒於此，有必要提供一種生產成本較低之訊號顯示器。 In view of this, it is necessary to provide a signal display with a lower production cost.
一種訊號顯示器，包括一光均化片、一正發光二極體及一軟性電路板，該正發光二極體對應該光均化片裝設於該軟性電路板上並與該軟性電路板電連接，該光均化片大致為一矩形板體，其具有一外表面及一與該外表面相對之內表面，該光均化片之內表面上對應該正發光二極體凸設一凸包，該光均化片用於調節正發光二極體發出之光線透過光均化片而到達光均化片外表面上之光線強度。 A signal display comprising a light homogenizing sheet, a positive light emitting diode and a flexible circuit board, the positive light emitting diode corresponding to the light homogenizing sheet being mounted on the flexible circuit board and electrically connected to the flexible circuit board The light homogenizing sheet is substantially a rectangular plate body having an outer surface and an inner surface opposite to the outer surface, and the inner surface of the light homogenizing sheet is convexly convex corresponding to the positive light emitting diode The light homogenizing sheet is used for adjusting the light intensity of the light emitted by the positive light emitting diode through the light homogenizing sheet to reach the outer surface of the light homogenizing sheet.
相較於習知技術，所述訊號顯示器採用了價格較便宜之正發光二極體以及製造成本較低之光均化片，較大地降低了整個訊號顯示器之生產成本，提升了產品之競爭力。 Compared with the prior art, the signal display adopts a cheaper positive light emitting diode and a light homogenizing film with lower manufacturing cost, which greatly reduces the production cost of the entire signal display and improves the competitiveness of the product. .
請參閱圖1及圖3所示本发明訊號顯示器之第一較佳實施例，該訊號顯示器100用於顯示攜帶型電子裝置之工作狀況，其包括一光均化片10、複數正發光二極體20、複數圖標30及一軟性電路板40。該正發光二極體20對應該光均化片10裝設於該軟性電路板40上並與該軟性電路板40電連接。該圖標30形成於該光均化片10之外表面上。 Referring to FIG. 1 and FIG. 3, a first preferred embodiment of the signal display device of the present invention is used to display the working condition of the portable electronic device, which includes a light homogenizing sheet 10 and a plurality of positive light emitting diodes. The body 20, the plurality of icons 30 and a flexible circuit board 40. The positive light emitting diode 20 is mounted on the flexible circuit board 40 corresponding to the optical smoothing plate 10 and electrically connected to the flexible circuit board 40. The icon 30 is formed on the outer surface of the light homogenizing sheet 10.
請一併參閱圖2及圖3，該光均化片10大致為一矩形板體，其具有一外表面11及一與該外表面11相對之內表面12。該內表面12上開設有複數凹槽14，每一凹槽14之底部133突設一凸包13。該每一凸包13具有一頂部131及一連接部132。該光均化片10於每一凸包13之頂部131處厚度最大，於凹槽14之底部133處厚度最小，並藉由該連接部 132緩慢過渡。該光均化片10之材料為一透光性材料，如聚碳酸酯(Polycarbonate,PC)。該光均化片10之連接部132用於調節透過連接部132之光線強度，使得正發光二極體20發出之光線透過該光均化片10而到達光均化片10之外表面11上之光線強度均勻。 Referring to FIG. 2 and FIG. 3 together, the light homogenizing sheet 10 is substantially a rectangular plate body having an outer surface 11 and an inner surface 12 opposite to the outer surface 11. A plurality of grooves 14 are defined in the inner surface 12, and a convex hull 13 protrudes from a bottom portion 133 of each of the grooves 14. Each convex hull 13 has a top portion 131 and a connecting portion 132. The light homogenizing sheet 10 has the largest thickness at the top 131 of each convex hull 13 and the smallest thickness at the bottom 133 of the recess 14 and is connected by the connecting portion. 132 slow transition. The material of the light homogenizing sheet 10 is a light transmissive material such as polycarbonate (PC). The connecting portion 132 of the light homogenizing sheet 10 is used to adjust the light intensity transmitted through the connecting portion 132 so that the light emitted from the positive emitting diode 20 passes through the light homogenizing sheet 10 to reach the outer surface 11 of the light homogenizing sheet 10. The light intensity is uniform.
正發光二極體20對應光均化片10之每一凸包13之頂部131裝設於軟性電路板40上。 The top portion 131 of each convex hull 13 of the light-emitting diode 20 corresponding to the light homogenizing sheet 10 is mounted on the flexible circuit board 40.
圖標30可以採用於光均化片10之外表面11噴塗油漆後以鐳射雕刻之方式形成，當然也可以採用印刷等其他方式形成。每一圖標30對應一個正發光二極體20。 The icon 30 may be formed by laser engraving on the outer surface 11 of the light homogenizing sheet 10, and may be formed by other means such as printing. Each icon 30 corresponds to a positive light emitting diode 20.
軟性電路板40設置於光均化片10之下方，其對應正發光二極體20之表面印刷有白色、淺色或銀色之油墨，用於將正發光二極體20射向軟性電路板40之光線反射回光均化片10上以提升正發光二極體20光線之利用率。 The flexible circuit board 40 is disposed under the light homogenizing sheet 10, and is printed with white, light or silver ink corresponding to the surface of the positive light emitting diode 20 for emitting the positive light emitting diode 20 to the flexible circuit board 40. The light is reflected back to the light homogenizing sheet 10 to enhance the utilization of the light of the positive light emitting diode 20.
組裝該訊號顯示器100時，首先將正發光二極體20裝設於軟性電路板40上；然後將帶有圖標30之光均化片10以內表面12面向正發光二極體20之方式設置於正發光二極體20上方，並使得每一凸包13之頂部131對準正發光二極體20即可。 When the signal display device 100 is assembled, the positive light emitting diode 20 is first mounted on the flexible circuit board 40; then the light homogenizing film 10 with the icon 30 is disposed on the inner surface 12 facing the positive light emitting diode 20 The positive light emitting diode 20 is above and the top 131 of each convex hull 13 is aligned with the positive light emitting diode 20.
當給正發光二極體20通電時，正發光二極體20發出之光線呈一扇形狀射向光均化片10，並透過該光均化片10到達光均化片10之外表面11，從而照亮外表面11之圖標30。該正發光二極體20射向光均化片10之光線之強度隨著距離正發光二極體20之變大而逐漸減弱。光均化片10之 厚度越大，透過該區域之光線強度減弱越多。因此，藉由光均化片10厚度之緩慢變化來調節到達其外表面11之光線強度，從而能夠使得該外表面11顯示之圖標30亮度均勻，避免了亮點之出現。 When the positive light emitting diode 20 is energized, the light emitted from the positive emitting diode 20 is directed to the light homogenizing sheet 10 in a shape, and passes through the light homogenizing sheet 10 to reach the outer surface 11 of the light homogenizing sheet 10. Thereby illuminating the icon 30 of the outer surface 11. The intensity of the light that the positive light emitting diode 20 emits toward the light homogenizing sheet 10 gradually decreases as the distance from the positive light emitting diode 20 becomes larger. Light homogenizing sheet 10 The greater the thickness, the more the light intensity that passes through the area diminishes. Therefore, the intensity of the light reaching the outer surface 11 is adjusted by the slow change in the thickness of the light homogenizing sheet 10, so that the brightness of the icon 30 displayed on the outer surface 11 can be made uniform, avoiding the occurrence of bright spots.
可以理解，連接部132之形狀與較多因素有關，如正發光二極體20發出之到達連接部132上之光線強度及正發光二極體20與光均化片10之間之距離等。 It can be understood that the shape of the connecting portion 132 is related to many factors, such as the intensity of light emitted from the positive light emitting diode 20 to the connecting portion 132 and the distance between the positive emitting diode 20 and the light homogenizing sheet 10.
請參閱圖4所示本发明訊號顯示器之第二較佳實施例，該訊號顯示器200與訊號顯示器100大致相同，其包括一光均化片50、複數正發光二極體60、複數圖標(圖未示)及一軟性電路板70。該正發光二極體60對應該光均化片50裝設於該軟性電路板70上並與該軟性電路板70電連接。該光均化片50大致為一矩形板體，其具有一外表面51及一與該外表面51相對之內表面52。該圖標形成於該光均化片50之外表面上。該內表面52上突設複數凸包53。該每一凸包53具有一頂部531、一連接部532及一底部533。該底部533與該內表面52相齊平。該光均化片50於每一凸包53之頂部531處厚度最大，於底部533處厚度最小，並藉由該連接部532緩慢過渡。 Referring to FIG. 4, a second preferred embodiment of the signal display device of the present invention is substantially the same as the signal display device 100. The signal display device 200 includes a light homogenizing sheet 50, a plurality of positive light emitting diodes 60, and a plurality of icons. Not shown) and a flexible circuit board 70. The positive light emitting diode 60 is mounted on the flexible circuit board 70 corresponding to the light homogenizing sheet 50 and electrically connected to the flexible circuit board 70. The light homogenizing sheet 50 is substantially a rectangular plate having an outer surface 51 and an inner surface 52 opposite the outer surface 51. This icon is formed on the outer surface of the light homogenizing sheet 50. A plurality of convex hulls 53 are protruded from the inner surface 52. Each convex hull 53 has a top 531, a connecting portion 532 and a bottom 533. The bottom 533 is flush with the inner surface 52. The light homogenizing sheet 50 has the largest thickness at the top 531 of each convex hull 53 and the smallest thickness at the bottom portion 533, and is slowly transitioned by the connecting portion 532.
