請參閱第一圖，其為習知技術電子裝置之顯示面板示意圖，圖中顯示面板1係與一電子裝置10之光源指示區101相結合，請參閱第二圖，其為顯示面板1之剖面視圖，包括一印刷電路板11(Printed circuit board，PCB)、多數個發光二極體12、一電源線13、一反射片14、一均光板15、一擴散片16以及一顯示蓋板17。Please refer to the first figure, which is a schematic view of a display panel of a prior art electronic device. The display panel 1 is combined with a light source indicating area 101 of an electronic device 10. Referring to the second figure, it is a cross section of the display panel 1. The view includes a printed circuit board (PCB), a plurality of light emitting diodes 12, a power line 13, a reflective sheet 14, a light equalizing plate 15, a diffusion sheet 16, and a display cover 17.
印刷電路板11係分別與上述發光二極體12以及該電源線13相連接，並藉由該電源線13所提供之電能驅動該發光二極體12發出光源，反射片14則是設置於上述發光二極體12之底部或周圍，其目的在於反射光源以避免漏光，均光板15以及擴散片16係設置在發光二極體12之上方，其主要功能在於擴散光源並將光源均勻化，顯示蓋板17則是設置在該擴散片16上方，其表面設有一透光區塊171以及一非透光區塊172，發光二極體12所發出之光線可以穿透該 透光區塊171，顯示面板1係利用光線的明暗或是閃爍次數，以便讓使用者能夠瞭解電子裝置1目前的狀態為何。The printed circuit board 11 is connected to the light-emitting diode 12 and the power line 13 respectively, and the light-emitting diode 12 is driven by the power provided by the power line 13 to emit a light source, and the reflective sheet 14 is disposed on the above. The bottom of the light-emitting diode 12 or the periphery thereof is intended to reflect the light source to avoid light leakage. The light-homogenizing plate 15 and the diffusion sheet 16 are disposed above the light-emitting diode 12, and its main function is to diffuse the light source and uniformize the light source. The cover plate 17 is disposed above the diffusion sheet 16, and has a transparent block 171 and a non-transparent block 172 on the surface thereof, and the light emitted by the LED 12 can penetrate the cover plate. In the light-transmissive block 171, the display panel 1 utilizes the brightness or the number of blinks of the light to allow the user to know the current state of the electronic device 1.
然而，習知技術電子裝置之顯示面板仍然有下列之缺點：a.習知技術之顯示面板的厚度太大：由於習知技術的組成元件過多，包括電路板、發光二極體、擴散片、均光板與顯示蓋板，這些元件組合之後所形成的顯示面板將會變得很厚，而無法獲得輕薄短小的電子裝置。However, the display panel of the prior art electronic device still has the following disadvantages: a. The thickness of the display panel of the prior art is too large: due to too many components of the prior art, including a circuit board, a light emitting diode, a diffusion sheet, The light-shielding plate and the display cover plate, the display panel formed by combining these components will become thick, and the thin and short electronic device cannot be obtained.
b.習知技術之顯示面板費用較高且組合不易：習知技術的組成元件過多，包括擴散片與均光板都是價格昂貴的光學元件，造成顯示面板的費用過高，組合上也較為困難。b. The display panel of the prior art is relatively expensive and the combination is not easy: the conventional technology has many components, including the diffusion sheet and the homogenizing plate, which are expensive optical components, which causes the display panel to be expensive and difficult to combine. .
c.習知技術之顯示面板在顯示二種顏色以上的光源時，會有混色的問題產生：當有些顯示面板需要使用二種以上顏色的光源時，習知技術之顯示面板在結構設計上，未考慮到不同色系光源之間會有混色的問題存在，而影響顯示品質。c. The display panel of the prior art has a problem of color mixing when displaying light sources of two or more colors: when some display panels need to use light sources of two or more colors, the display panel of the prior art is structurally designed. The problem of color mixing between different color light sources is not considered, and the display quality is affected.
本發明提供一種電子裝置之顯示面板，該顯示面板的組成元件較少，不僅組裝容易，費用也較為便宜，並且不會有混色的問題產生。The present invention provides a display panel of an electronic device, which has fewer components, is not only easy to assemble, but also inexpensive, and has no problem of color mixing.
本發明之顯示面板結合於一電子裝置之光源指 示區，包括一雙層板、一軟性電路板以及一顯示蓋板。The display panel of the present invention is coupled to a light source of an electronic device The display area includes a double layer board, a flexible circuit board and a display cover.
其中，雙層板包括一反射板以及一透明板，透明板形成於反射板上方，且具有一凹槽以及一斜面。The double-layer board includes a reflecting board and a transparent board. The transparent board is formed above the reflecting board and has a groove and a slope.
軟性電路板具有一側照式發光二極體，該側照式發光二極體容置於透明板之凹槽處，並朝向該斜面發射光線，該顯示蓋板係覆蓋於該雙層板與該軟性電路板的上方，且具有一透光區塊。The flexible circuit board has a side-illuminated LED, and the side-illuminated LED is received in the recess of the transparent plate and emits light toward the inclined surface, and the display cover covers the double-layer board The flexible circuit board is above and has a light transmitting block.
由於光線在透明板內部的強度會隨著其行進的距離長度而逐漸減弱，因此，本發明之透明板斜面之厚度相對於側照式發光二極體由近而遠遞減，也就是說，斜面越靠近凹槽處之厚度越大，反之，厚度則越薄，其目的在於使每一個光線在從斜面射出之前，在透明板內部所行進的距離相同，進而獲得較均勻的光線輸出。Since the intensity of the light inside the transparent plate gradually decreases with the length of the distance traveled by the transparent plate, the thickness of the inclined surface of the transparent plate of the present invention decreases from near to far from the side-illuminated light-emitting diode, that is, the inclined surface The closer to the groove, the greater the thickness, and vice versa, the thinner the thickness, the purpose of which is to make each light travel the same distance inside the transparent plate before exiting from the bevel, thereby obtaining a more uniform light output.
因此，本發明之顯示面板只需要一個透明板即可達到光線均勻的效果，不需要額外設置擴散片和均光板，相較於習知技術而言，本發明不僅組成元件少、組裝容易、整體厚度也會較薄而費用也較便宜。Therefore, the display panel of the present invention only needs one transparent plate to achieve uniform light effect, and does not need to additionally provide a diffusion sheet and a homogenizing plate. Compared with the prior art, the invention not only has fewer components, is easy to assemble, and is overall. The thickness will also be thinner and the cost will be cheaper.
另外，在本發明之顯示面板中，雙層板也可以是具有多數個凹槽以及多數個斜面，而軟性電路板則是具有多數個側照式發光二極體，並分別容置於上述凹槽中，其中上述側照式發光二極體分別提供不同顏色之光源，而上述側照式發光二極體彼此之間則是利用該反射板隔開。因此，當不同顏色之側照式發光二極體同時發光時，將不會有混色的問題產生。In addition, in the display panel of the present invention, the double-layer board may have a plurality of grooves and a plurality of inclined surfaces, and the flexible circuit board has a plurality of side-illuminated light-emitting diodes, and are respectively accommodated in the concave surface. In the slot, the side-illuminated LEDs respectively provide light sources of different colors, and the side-illuminated LEDs are separated from each other by the reflector. Therefore, when the side-illuminated LEDs of different colors emit light at the same time, there will be no problem of color mixing.
由以上述可知，本發明之電子裝置之顯示面板相較於先前技術而言，不僅可以減少組成元件，同時可以達到光源均勻化的效果，在使用不同色系之光源進 行顯示時，本發明更利用反射板加以阻隔以避免混色的問題產生。As can be seen from the above, the display panel of the electronic device of the present invention can not only reduce the constituent elements but also achieve the effect of uniformizing the light source compared to the prior art, and use the light source of different color systems. When the line is displayed, the present invention further utilizes a reflecting plate to block the problem of color mixing.
本發明所採用的具體實施例，將藉由以下之實施例及圖式作進一步之說明。The specific embodiments of the present invention will be further described by the following examples and drawings.
本發明之顯示面板係結合於一電子裝置之光源指示區，該電子裝置可以是PDA、筆記型電腦、手機或是音響等。The display panel of the present invention is coupled to a light source indicating area of an electronic device, which may be a PDA, a notebook computer, a mobile phone or an audio device.
請參閱第三圖所示，其為本發明之顯示面板之剖面圖，圖中顯示面板30包括一雙層板31、一軟性電路板32以及一顯示蓋板34。Referring to the third figure, which is a cross-sectional view of the display panel of the present invention, the display panel 30 includes a double layer 31, a flexible circuit board 32, and a display cover 34.
其中，雙層板31包括一反射板311以及一透明板312，反射板311為白色ABS材質，且具有良好的反射特性。The double-layer board 31 includes a reflective board 311 and a transparent board 312. The reflective board 311 is made of white ABS material and has good reflective characteristics.
透明板312形成於反射板311上方，且具有一凹槽313以及一斜面314，該斜面314的傾斜角度係介於10~30度之間並以20度為最佳，其中該斜面314之厚度相對於凹槽313由近而遠遞減，也就是說，斜面越靠近凹槽313處之厚度越大，反之，厚度則越薄，透明板312所採用的材料為聚碳酸酯(Polycarbonate，PC)。The transparent plate 312 is formed on the reflective plate 311 and has a groove 313 and a slope 314. The inclined surface 314 has an inclination angle of 10 to 30 degrees and is preferably 20 degrees, wherein the thickness of the slope 314 is 315. The thickness of the transparent surface of the transparent plate 312 is polycarbonate (Polycarbonate, PC). .
軟性電路板32具有一側照式發光二極體33並容置於該透明板312之凹槽313處，且該軟性電路板32可提供側照式發光二極體33電源，而該側照式發光二極體33則是朝向該斜面314發出光線。The flexible circuit board 32 has a side-lit LED 33 and is received in the recess 313 of the transparent board 312, and the flexible circuit board 32 can provide a side-lit LED 33 power supply. The light-emitting diode 33 emits light toward the slope 314.
顯示蓋板34係覆蓋於該雙層板31與該軟性電路 板32的上方，其中該顯示蓋板34具有一透光區塊341以及非透光區塊342，其製作方式可以利用不透光漆料塗在一透明之聚碳酸酯表面，再以雷射雕刻方式雕刻出透光區塊341，使光線可以透過該透光區塊341顯示出來。A display cover 34 covers the double layer board 31 and the flexible circuit Above the plate 32, the display cover 34 has a light-transmissive block 341 and a non-transparent block 342, which can be fabricated by coating the surface of a transparent polycarbonate with an opaque paint, and then using a laser. The light-transmissive block 341 is engraved in an engraving manner so that light can be displayed through the light-transmissive block 341.
請參閱第四圖所示，其為光線在本發明之雙層板內部行進之示意圖，光線在進入雙層板31之後，會在透明板312內部進行折射，並在碰到反射板311之後進行反射，最後再由透明板312之斜面314射出，但由於光線的強度會隨著其在透明板312內部行進的距離長度而逐漸減弱。Referring to the fourth figure, which is a schematic diagram of light traveling inside the double-layered panel of the present invention, after entering the double-layered board 31, the light will be refracted inside the transparent plate 312 and after the reflective plate 311 is hit. The reflection is finally ejected by the bevel 314 of the transparent plate 312, but the intensity of the light gradually decreases as it travels within the transparent plate 312.
為了能夠在斜面314上獲得均勻的光線輸出，本發明之透明板312的斜面314在設計上越靠近凹槽313厚度越大，反之，厚度越薄，其目的在於使每一個光線在從斜面314射出之前，在透明板312內部所行進的距離相同，如圖中之光線A與光線B所示，斜面314的設計可以使二光線的行進距離差異降至最低，進而獲得較均勻的光線輸出。In order to obtain a uniform light output on the slope 314, the slope 314 of the transparent plate 312 of the present invention is designed to be closer to the groove 313 in thickness. Conversely, the thinner the thickness, the purpose is to cause each light to be emitted from the slope 314. Previously, the distance traveled inside the transparent plate 312 is the same, as shown by the light A and the light B in the figure, the design of the inclined surface 314 can minimize the difference in the travel distance of the two rays, thereby obtaining a relatively uniform light output.
因此，本發明之顯示面板只需要一個透明板即可達到光線均勻的效果，不需要額外設置擴散片和均光板，相較於習知技術而言，本發明不僅組成元件少、組裝容易、整體厚度也會較薄而費用也較便宜。Therefore, the display panel of the present invention only needs one transparent plate to achieve uniform light effect, and does not need to additionally provide a diffusion sheet and a homogenizing plate. Compared with the prior art, the invention not only has fewer components, is easy to assemble, and is overall. The thickness will also be thinner and the cost will be cheaper.
請參閱第五圖所示，其為本發明之顯示面板之另一實施例圖，本實施例主要是將雙層板31設計成具有多數個凹槽313以及多數個斜面314，同時軟性電路板32則是具有多數個側照式發光二極體33(圖中未示)並分別容置於上述凹槽313中。Please refer to the fifth figure, which is another embodiment of the display panel of the present invention. The embodiment mainly designs the double-layer board 31 to have a plurality of grooves 313 and a plurality of inclined surfaces 314, and a flexible circuit board. 32 has a plurality of side-illuminated light-emitting diodes 33 (not shown) and are respectively accommodated in the above-mentioned grooves 313.
上述側照式發光二極體33可提供相同顏色之光 源，也可以是分別提供不同顏色之光源。若為不同顏色之光源，則上述側照式發光二極體33彼此之間係利用該反射板311隔開。因此，當不同顏色之側照式發光二極體33同時發光時，將不會有混色的問題產生。The above-mentioned side-illuminated LEDs 33 can provide the same color of light The source may also be a light source that provides different colors, respectively. In the case of light sources of different colors, the side-illuminated LEDs 33 are separated from each other by the reflecting plate 311. Therefore, when the side-illuminated LEDs 33 of different colors are simultaneously illuminated, there is no problem of color mixing.
由以上述可知，本發明之電子裝置之顯示面板相較於先前技術而言，不僅可以減少組成元件，同時可以達到光源均勻化的效果，在使用不同色系之光源進行顯示時，本發明更利用反射板加以阻隔以避免混色的問題產生。As can be seen from the above, the display panel of the electronic device of the present invention can not only reduce the constituent elements but also achieve the effect of uniformizing the light source compared to the prior art, and the present invention is more effective when displaying light sources using different color systems. Use a reflector to block the problem of mixing.
以上所述，僅為本發明之較佳實施例說明，舉凡所屬技術領域中具有通常知識者當可依據本發明之上述實施例說明而作其它種種之改良及變化。然而這些依據本發明實施例所作的種種改良及變化，當仍屬於本發明之發明精神及界定之專利範圍內。The above description is only for the preferred embodiment of the present invention, and those skilled in the art can make various other modifications and changes as described in the above embodiments of the present invention.
