Description
本發明係關於一種液晶顯示器以及一種應用於此液晶顯示器的節能指示方法，尤指一種可移除點亮其電源指示燈所需之發光二極體的材料成本並節省下點亮發光二極體所需耗費之能源的液晶顯示器，以及一種使得液晶顯示器之電源指示燈可在一外界光線微弱的環境中容易發現電源按鈕位置的節能指示方法。 The present invention relates to a liquid crystal display and an energy-saving indicating method applied to the liquid crystal display, and more particularly to a material cost of the light-emitting diode required to remove the power light indicator and to save the light-emitting diode. A liquid crystal display that requires an energy source, and an energy-saving indicating method that makes the power indicator of the liquid crystal display easy to find the position of the power button in an environment where the external light is weak.
在習知的液晶顯示器中，一般均使用一個內含雙色或兩個異色的發光二極體做為其電源指示燈的光源，而這些發光二極體的成本一個約0.1美金。而且，習知的液晶顯示器即便處於關機狀態時，其電源指示燈仍需維持在一開啟狀態(如顯示出紅燈)，以顯示其電源按鈕位置，使得使用者可在一外界光線微弱的環境中發現此電源指示燈的位置。也就是說，一般習知的液晶顯示器插上插頭，無論其所處的狀態為何，其電源指示燈便需持續地被點亮。此時，做為其電源指示燈之光源的一個內含雙色或兩個異色的發光二極體便持續地耗費能源。雖然發光二極體的耗電量已經遠小於一般的白熾燈管，但長久下來，所耗費的能源也相當可觀，同時也減低其壽命。 In the conventional liquid crystal display, a light-emitting diode containing two colors or two different colors is generally used as a light source of the power indicator light, and the cost of these light-emitting diodes is about 0.1 US dollars. Moreover, even when the conventional liquid crystal display is in the off state, its power indicator light needs to be maintained in an open state (such as displaying a red light) to display the position of the power button, so that the user can be in an environment with weak external light. The location of this power light was found. That is to say, the conventional liquid crystal display is plugged in, and the power indicator light needs to be continuously illuminated regardless of the state in which it is placed. At this time, a light-emitting diode containing two or two different colors as a light source of the power indicator lamp continuously consumes energy. Although the power consumption of the light-emitting diodes is much smaller than that of ordinary incandescent tubes, the energy consumption is considerable over a long period of time, and it also reduces its life.
綜上所述，習知的液晶顯示器所具有的電源指示燈不僅需要增加發光二極體的材料成本，更會持續地耗費能源，相當不符合節能減碳的環保政策。 In summary, the conventional power supply indicator of the liquid crystal display not only needs to increase the material cost of the light-emitting diode, but also continuously consumes energy, which is quite inconsistent with the environmental protection policy of energy saving and carbon reduction.
因此，業界需要一種可移除其電源指示燈所需之發光二極體的材料成本並節省下點亮發光二極體所需耗費之能源的液晶顯示器，以及一種使得液晶顯示器之電源指示燈可在一外界光線微弱的環境中容易發現電源按鈕位置的節能指示方法。 Therefore, the industry needs a liquid crystal display that can remove the material cost of the light-emitting diode required for its power indicator light and saves the energy required to illuminate the light-emitting diode, and a power indicator light for the liquid crystal display can be It is easy to find the energy-saving indication method of the position of the power button in an environment where the external light is weak.

而如圖1所示，雖然在本實施例中，背光模組12係為一側光式背光模組，但本發明一實施例之液晶顯示器仍可依據設計，而具有一背光式背光模組。此外，雖然如圖1所示，複數個光源單元121係為二組4支冷陰極射線燈管1211、1212，但本發明一實施例之液晶顯示器之背光模組仍可依據設計，而具有不同類型之複數個光源單元，如複數個發光二極體燈條或複數個發光二極體，且數目也不拘限於二組4支。同理，如雖然如圖1所示，此二組4支冷陰極射線燈管1211、1212係分別設置於導光板122的上下兩側，但此二組4支冷陰極射線燈管1211、1212仍可依據設計，而分別設 置於導光板122的左右兩側。最後，亦如圖1所示，前述之引光凸部1222的位置係鄰近於冷陰極射線燈管1211，以方便擷取冷陰極射線燈管1211所發出的光線進行顯示。 As shown in FIG. 1 , in the embodiment, the backlight module 12 is a one-side optical backlight module, but the liquid crystal display according to an embodiment of the present invention can still have a backlight backlight module according to the design. . In addition, as shown in FIG. 1 , the plurality of light source units 121 are two sets of four cold cathode ray tubes 1211 and 1212 , but the backlight module of the liquid crystal display according to an embodiment of the present invention may still have different designs according to the design. A plurality of light source units of the type, such as a plurality of light-emitting diode light bars or a plurality of light-emitting diodes, and the number is not limited to two groups of four. Similarly, as shown in FIG. 1, the two sets of four cold cathode ray tubes 1211 and 1212 are respectively disposed on the upper and lower sides of the light guide plate 122, but the two sets of four cold cathode ray tubes 1211 and 1212 are respectively arranged. Can still be set separately according to the design They are placed on the left and right sides of the light guide plate 122. Finally, as shown in FIG. 1, the position of the light guiding convex portion 1222 is adjacent to the cold cathode fluorescent lamp tube 1211, so as to facilitate the display of the light emitted by the cold cathode fluorescent lamp 1211.
所以，當本發明一實施例之液晶顯示器處於一「開機狀態」時，光源單元121所發出的光線便持續經由導光板122的導引而到達引光凸部1222，使得引光凸部1222維持一「明亮狀態」。此外，如前所述，由於節能指示單元15係設置於引光凸部1222上，且其導光上套部152具有一導光指示面1521，導光指示面1521更包含透光指示區1523，所以前述到達引光凸部1222的光線便可持續地通過透光指示區1523而到達外界，達到顯示本發明一實施例之液晶顯示器目前係處於一「開機狀態」的「省能白光」效果。除此之外，雖然螢光指示區1512也會因為前述之光線的照射而發出螢光，但由於透光指示區1523之面積大於螢光指示區1512之面積，所以相較於通過透光指示區1523之透射光線的光量，螢光指示區1512所發射出之螢光的光量便顯得極低而無法被辨識出來。 Therefore, when the liquid crystal display device of the embodiment of the present invention is in a "on state", the light emitted by the light source unit 121 continues to be guided by the light guide plate 122 to reach the light guiding convex portion 1222, so that the light guiding convex portion 1222 is maintained. A "bright state." In addition, as described above, since the energy-saving indicating unit 15 is disposed on the light-emitting convex portion 1222, and the light-guiding upper sleeve portion 152 has a light-guiding indicating surface 1521, the light-guiding indicating surface 1521 further includes a light-transmitting indicating area 1523. Therefore, the light reaching the light guiding convex portion 1222 can continuously reach the outside through the light transmitting indicating area 1523, so as to achieve the "energy saving white light" effect that the liquid crystal display according to an embodiment of the present invention is currently in a "power on state". . In addition, although the fluorescent indicating area 1512 also emits fluorescence due to the irradiation of the aforementioned light, since the area of the light indicating area 1523 is larger than the area of the fluorescent indicating area 1512, it is compared with the light passing indication. The amount of light transmitted by the region 1523, the amount of fluorescent light emitted by the fluorescent indicating region 1512, appears to be extremely low and cannot be recognized.
另一方面，當本發明一實施例之液晶顯示器處於一「待機狀態」時，前述之控制單元(圖中未示)便關閉顯示控制開關(圖中未示)並每隔一段時間輪流點亮複數個光源單元121(即冷陰極射線燈管1211、1212)。所以，這些光源單元121所發出的光線便間歇地經由導光板122的導引而到達引光凸部1222，使得引光凸部1222間歇地呈現一「忽明忽暗狀態」。需注意的是，為了平衡前述之二組4支冷陰極射線 燈管1211、1212的使用時間，前述之二組4支冷陰極射線燈管1211、1212可每隔一段時間被「輪流地」點亮。如此，螢光指示區1512便會因為此一光線的照射而發出「間歇螢光」。而且，在本實施例中，螢光指示區1512係塗佈有一會發出有色螢光之螢光層。此時，由於此時並無光線通過透光指示區1523而到達外界，所以螢光指示區1512所發出的螢光便可被辨識出來。如此，只要複數個光源單元121輪流被點亮的時間間隔短於構成前述之螢光層之螢光物質的亮度半衰期，螢光指示區1512便會持續地發出有色螢光，達到顯示本發明一實施例之液晶顯示器目前係處於一「待機狀態」的「間歇螢光」效果。 On the other hand, when the liquid crystal display according to an embodiment of the present invention is in a "standby state", the aforementioned control unit (not shown) turns off the display control switch (not shown) and turns on at regular intervals. A plurality of light source units 121 (i.e., cold cathode ray tubes 1211, 1212). Therefore, the light emitted by the light source unit 121 intermittently reaches the light guiding convex portion 1222 via the guiding of the light guide plate 122, so that the light guiding convex portion 1222 intermittently presents a "flickering state". It should be noted that in order to balance the aforementioned two sets of four cold cathode rays The use time of the lamps 1211 and 1212, the two sets of four cold cathode ray tubes 1211 and 1212 can be "rotated" at regular intervals. In this way, the fluorescent indication area 1512 will emit "intermittent fluorescence" due to the irradiation of the light. Moreover, in the present embodiment, the fluorescent indicating region 1512 is coated with a fluorescent layer that emits colored fluorescent light. At this time, since no light passes through the light-transmitting indicating area 1523 and reaches the outside, the fluorescent light emitted from the fluorescent indicating area 1512 can be recognized. Thus, as long as the time interval in which the plurality of light source units 121 are alternately illuminated is shorter than the luminance half-life of the fluorescent material constituting the fluorescent layer, the fluorescent indicating region 1512 continuously emits colored fluorescent light to achieve the present invention. The liquid crystal display of the embodiment is currently in a "standby state" "intermittent fluorescence" effect.
最後，當本發明一實施例之液晶顯示器處於一「關機狀態」時，前述之控制單元(圖中未示)便關閉顯示控制開關(圖中未示)並熄滅全部光源單元121。最後，控制單元(圖中未示)再關閉電源控制開關(圖中未示)。如此，即便在一外界光線微弱的環境中，由於節能指示單元15之導光底座151的螢光指示區1512仍可由於外界微量光線的照射而發出「微弱螢光」，而且此時並無其他光線會通過透光指示區1523而到達外界，所以即便螢光指示區1512所發出的螢光亮度較低，其仍便可被辨識出來。因此，即便處在一外界光線微弱的環境中，前述之節能指示單元15仍可容易發現電源按鈕16位置。 Finally, when the liquid crystal display according to an embodiment of the present invention is in a "off state", the aforementioned control unit (not shown) turns off the display control switch (not shown) and turns off all of the light source units 121. Finally, the control unit (not shown) turns off the power control switch (not shown). In this way, even in an environment where the external light is weak, the fluorescent indication area 1512 of the light guiding base 151 of the energy saving indicating unit 15 can emit "weak fluorescence" due to the irradiation of the external light, and there is no other at this time. The light will reach the outside through the light indicating area 1523, so even if the brightness of the fluorescent light emitted by the fluorescent indicating area 1512 is low, it can be recognized. Therefore, even in an environment where the external light is weak, the aforementioned energy saving indicating unit 15 can easily find the position of the power button 16.
因此，本發明一實施例之液晶顯示器僅需將到達其導光板之光線進一步導引至一位於其節能指示單元之下側的 引光凸部，本發明一實施例之液晶顯示器即可藉由設置於其節能指示單元之導光上套部之導光指示面的「透光指示區」以及設置於其節能指示單元之導光底座之「螢光指示區」顯示出其所處之狀態(開機狀態、待機狀態或關機狀態)。而且，由於無須額外設置前述之一或兩個做為其電源指示燈之光源的發光二極體，本發明一實施例之液晶顯示器便可移除前述之一個內含雙色或兩個異色發光二極體的材料成本，更可節省下點亮這些發光二極體所需耗費的能源。 Therefore, the liquid crystal display according to an embodiment of the present invention only needs to further guide the light reaching the light guide plate to a lower side of the energy saving indicating unit. The light-emitting convex portion, the liquid crystal display according to an embodiment of the present invention can be disposed by the "light-transmitting indication area" of the light-guiding indicating surface of the light-guiding upper sleeve portion of the energy-saving indicating unit, and the guide disposed on the energy-saving indicating unit The "fluorescent indicator area" of the light base shows the status (power on state, standby state, or power off state). Moreover, since there is no need to additionally provide one or two of the light-emitting diodes as the light source of the power indicator light, the liquid crystal display according to an embodiment of the present invention can remove the aforementioned one of the two-color or two-color light-emitting diodes. The material cost of the polar body can save the energy required to light up these light-emitting diodes.
如圖3所示，本發明另一實施例之液晶顯示器包括：一承載底板31、一設置於承載底板31上的背光模組32、一設置於背光模組32上並具有一顯示控制開關(圖中未示)、一電源控制開關(圖中未示)與一控制單元(圖中未示)的液晶顯示單元33、一開設有一開口341的面框34、一節能指示單元35以及一位於節能指示單元35的螢光指示區3512之後的電源按鈕36。其中，前述之控制單元(圖中未示)係分別與電源按鈕36、顯示控制開關(圖中未示)以及電源控制開關(圖中未示)電性耦合。此外，承載底板31與面框34互相套合並將背光模組32、液晶顯示單元33、節能指示單元35以及電源按鈕36容納於兩者之間。 As shown in FIG. 3, a liquid crystal display according to another embodiment of the present invention includes a carrier substrate 31, a backlight module 32 disposed on the carrier substrate 31, a backlight module 32, and a display control switch ( A power control switch (not shown), a liquid crystal display unit 33 of a control unit (not shown), a face frame 34 having an opening 341, an energy saving indicating unit 35, and a The fluorescent indicator of the energy saving indicating unit 35 indicates the power button 36 after the area 3512.

In addition, the carrying substrate 31 and the face frame 34 are sleeved with each other to house the backlight module 32, the liquid crystal display unit 33, the energy saving indicating unit 35, and the power button 36 therebetween.
此外，背光模組32包含複數個光源單元3211、3212、3213、3214與一導光板322，導光板322則設置於複數個光源單元321之一側。而且，如圖3所示，導光板322於一邊緣側面之凸出處3221設有一引光凸部3222。雖然在本實施例 中，凸出處3221係位於導光板322之水平方向的邊緣側面，但本發明之液晶顯示器之背光模組所具有的導光板亦可在其垂直方向的邊緣側面設有一凸出處，而一引光凸部便設置於此凸出處。 In addition, the backlight module 32 includes a plurality of light source units 3211, 3212, 3213, and 3214 and a light guide plate 322, and the light guide plate 322 is disposed on one side of the plurality of light source units 321 . Moreover, as shown in FIG. 3, the light guide plate 322 is provided with a light-emitting convex portion 3222 at a convex portion 3221 of an edge side. Although in this embodiment The bulging portion 3221 is located on the side of the edge of the light guide plate 322 in the horizontal direction. However, the backlight module of the liquid crystal display of the present invention may also have a convex portion on the side of the edge in the vertical direction, and a light guide is provided. The convex portion is placed at this convex portion.
另一方面，如圖3及圖4A立體圖所示，本發明另一實施例之液晶顯示器所具有的節能指示單元35包含一導光底座351與一導光上套部352，且導光上套部352對應套入前述之面框34的開口341。此外，導光上套部352係具有一導光指示面3521及一由導光指示面3521垂直延伸而出的導光週緣3522，導光指示面3521並包含一透光指示區3523。另一方面，導光底座351包含一支撐座3511以及一凸出於支撐座3511一特定距離D之螢光指示區3512。其中，螢光指示區3512佈塗一螢光層且此特定距離D係可調整以控制從螢光指示區3512所發出之螢光的強弱。 On the other hand, as shown in the perspective view of FIG. 3 and FIG. 4A, the energy-saving indicating unit 35 of the liquid crystal display according to another embodiment of the present invention includes a light guiding base 351 and a light guiding upper sleeve portion 352, and the light guiding sleeve is provided. The portion 352 is fitted into the opening 341 of the face frame 34 described above. In addition, the light guiding upper portion 352 has a light guiding surface 3521 and a light guiding periphery 3522 extending perpendicularly from the light guiding surface 3521. The light guiding surface 3521 includes a light indicating area 3523. On the other hand, the light guiding base 351 includes a supporting base 3511 and a fluorescent indicating area 3512 protruding from the supporting base 3511 by a specific distance D. The fluorescent indicator area 3512 is coated with a fluorescent layer and the specific distance D is adjustable to control the intensity of the fluorescent light emitted from the fluorescent indicating area 3512.
而如圖4B頂視圖所示，前述之透光指示區3523之面積係大於螢光指示區3512之面積，且螢光指示區3512係將透光指示區3523於導光底座351之投影區域圍繞於其中。但是，在其他的實施例中，透光指示區於導光底座之投影區域亦可將螢光指示區圍繞於其中。另一方面，雖然在本實施例中，螢光指示區3512係為中間內凹、外緣實心的態樣，而導光上套部352則為中間實心、外緣內凹的態樣，但其他的實施例中，螢光指示區及導光上套部亦可具有其他類型的態樣。除此之外，雖然在本實施例中，導光指示面3521 之形狀係為橢圓形，但導光指示面3521之形狀仍可依據不同設計需求，而為圓形、三角形、矩形或多邊形。 As shown in the top view of FIG. 4B, the area of the light-transmitting indication area 3523 is larger than the area of the fluorescent indication area 3512, and the fluorescent indication area 3512 surrounds the light-emitting indication area 3523 around the projection area of the light-guiding base 351. In it. However, in other embodiments, the light-emitting indication area may surround the fluorescent indicator area in the projection area of the light-guiding base. On the other hand, in the present embodiment, the fluorescent indicating area 3512 is in the middle concave and the outer edge is solid, and the light guiding upper portion 352 is in the middle solid and the outer edge concave, but In other embodiments, the fluorescent indicator area and the light guiding upper sleeve may have other types of aspects. In addition to this, although in the present embodiment, the light guiding surface 3521 The shape is elliptical, but the shape of the light guiding surface 3521 can still be circular, triangular, rectangular or polygonal according to different design requirements.
再如圖4A立體圖及4C側視圖所示，前述之導光底座351更包括二支自導光底座351之支撐座3511偏離中心軸線延伸而出的彈性支撐架3513、3514，且這二支彈性支撐架3513、3514係頂抵於承載底板31。此外，在本實施例中，節能指示單元35係為一電源指示燈，且前述之電源按鈕36係位於節能指示單元35的螢光指示區3512之後，且相對於彈性支撐架3513、3514的另一邊緣以求3點平衡。電源按鈕36並夾置於導光底座351與承載底板31之間，如圖4C所示。如此，當節能指示單元35被按壓而觸發電源按鈕36後，節能指示單元35便能自動地回復至其原先的位置，以預備接受下一次按壓。 As shown in the perspective view of FIG. 4A and the side view of FIG. 4C, the light guide base 351 further includes two elastic support frames 3513 and 3514 extending from the support base 3511 of the light guide base 351 from the central axis, and the two elastic members are elastic. The support frames 3513, 3514 are abutted against the carrier bottom plate 31. In addition, in the embodiment, the energy saving indicating unit 35 is a power indicator light, and the foregoing power button 36 is located behind the fluorescent indicating area 3512 of the energy saving indicating unit 35, and is opposite to the elastic supporting frames 3513, 3514. One edge is to balance at 3 points. The power button 36 is sandwiched between the light guiding base 351 and the carrying substrate 31 as shown in FIG. 4C. Thus, when the energy saving indicating unit 35 is pressed to trigger the power button 36, the energy saving indicating unit 35 can automatically return to its original position to prepare to accept the next pressing.
除此之外，在本實施例中，前述之控制器單元(圖中未示)係為一微控制器(MCU)，且其依據本發明另一實施例之液晶顯示器所處之狀態(開機狀態、待機狀態或關機狀態)而分別控制電源控制開關(圖中未示)、光源單元321以及顯示控制開關(圖中未示)的開關狀態，以取代習知的電源指示燈的燈號表示方式並使得節能指示單元35(電源指示燈)可在一外界光線微弱的環境中容易發現電源按鈕位置。 In addition, in this embodiment, the foregoing controller unit (not shown) is a microcontroller (MCU), and the state of the liquid crystal display according to another embodiment of the present invention is turned on. In the state, the standby state, or the power-off state, the switch states of the power control switch (not shown), the light source unit 321 and the display control switch (not shown) are respectively controlled to replace the light indicator of the conventional power indicator. The mode and the energy-saving indicating unit 35 (power indicator light) can easily find the power button position in an environment where the external light is weak.
而如圖3所示，雖然在本實施例中，背光模組32係為一背光式背光模組，但本發明另一實施例之液晶顯示器仍可依據設計，而具有一側光式背光模組。此外，雖然如圖3所示，複數個光源單元321係為白光發光二極體3211、3212、 3213、3214，但本發明另一實施例之液晶顯示器之背光模組仍可依據設計，而具有不同類型之複數個光源單元，如複數個發光二極體燈條或複數個冷陰極射線燈管，且數目也不拘限於四。同理，如雖然如圖3所示，這些白光發光二極體3211、3212、3213、3214係分別設置於導光板322的上側靠上緣處，但這些白光發光二極體3211、3212、3213、3214仍可依據設計，而分別設置於整個導光板322的下側，如靠下緣處。 As shown in FIG. 3, in the embodiment, the backlight module 32 is a backlight type backlight module, but the liquid crystal display according to another embodiment of the present invention can still have a side light type backlight module according to the design. group. In addition, although as shown in FIG. 3, the plurality of light source units 321 are white light emitting diodes 3211, 3212. 3213, 3214, but the backlight module of the liquid crystal display according to another embodiment of the present invention may still have a plurality of light source units of different types according to the design, such as a plurality of light emitting diode light strips or a plurality of cold cathode fluorescent light tubes. And the number is not limited to four. Similarly, as shown in FIG. 3, the white light emitting diodes 3211, 3212, 3213, and 3214 are respectively disposed on the upper edge of the upper side of the light guide plate 322, but the white light emitting diodes 3211, 3212, and 3213 are respectively disposed. The 3214 can still be disposed on the lower side of the entire light guide plate 322, such as at the lower edge, depending on the design.
所以，當本發明另一實施例之液晶顯示器處於一「開機狀態」時，光源單元321所發出的光線便持續經由導光板322的導引而到達引光凸部3222，使得引光凸部3222維持一「明亮狀態」。此外，如前所述，由於節能指示單元35係設置於引光凸部3222上，且其導光上套部352具有一導光指示面3521，導光指示面3521更包含透光指示區3523，所以前述到達引光凸部3222的光線便可持續地通過透光指示區3523而到達外界，達到顯示本發明另一實施例之液晶顯示器目前係處於一「開機狀態」的「省能白光」效果。除此之外，雖然螢光指示區3512也會因為前述之光線的照射而發出螢光，但由於透光指示區3523之面積大於螢光指示區3512之面積，所以相較於通過透光指示區3523之透射光線的光量，螢光指示區3512所發射出之螢光的光量便顯得極低而無法被辨識出來。 Therefore, when the liquid crystal display according to another embodiment of the present invention is in a "on state", the light emitted by the light source unit 321 continues to be guided by the light guide plate 322 to reach the light guiding convex portion 3222, so that the light guiding convex portion 3222 Maintain a "bright state." In addition, as described above, since the energy-saving indicating unit 35 is disposed on the light-emitting convex portion 3222, and the light-guiding upper sleeve portion 352 has a light-guiding indicating surface 3521, the light-guiding indicating surface 3521 further includes a light-transmitting indicating area 3523. Therefore, the light reaching the light guiding convex portion 3222 can continuously pass through the light transmitting indicating area 3523 to reach the outside world, so that the liquid crystal display device showing another embodiment of the present invention is currently in a "power saving state". effect. In addition, although the fluorescent indication area 3512 also emits fluorescence due to the illumination of the aforementioned light, since the area of the light-transmitting indication area 3523 is larger than the area of the fluorescent indication area 3512, it is compared with the light transmission indication. The amount of light transmitted by the area 3523, the amount of fluorescent light emitted by the fluorescent indicating area 3512, appears to be extremely low and cannot be recognized.
另一方面，當本發明另一實施例之液晶顯示器處於一「待機狀態」時，前述之控制單元(圖中未示)便關閉顯示控 制開關(圖中未示)並每隔一段時間輪流點亮複數個光源單元321(即白光發光二極體3211、3212、3213、3214)。所以，這些光源單元321所發出的光線便間歇地經由導光板322的導引而到達引光凸部3222，使得引光凸部3222間歇地呈現一「忽明忽暗狀態」。需注意的是，為了平衡前述之白光發光二極體3211、3212、3213、3214，這些白光發光二極體3211、3212、3213、3214可每隔一段時間被「輪流地」點亮。如此，螢光指示區3512便會因為此一光線的照射而發出「間歇螢光」。而且，在本實施例中，螢光指示區3512係塗佈有一會發出有色螢光之螢光層。此時，由於此時並無光線通過透光指示區3523而到達外界，所以螢光指示區3512所發出的螢光便可被辨識出來。如此，只要複數個光源單元321(即白光發光二極體3211、3212、3213、3214)輪流被點亮的時間間隔短於構成前述之螢光層之螢光物質的亮度半衰期，螢光指示區3512便會持續地發出有色螢光，達到顯示本發明另一實施例之液晶顯示器目前係處於一「待機狀態」的「間歇螢光」效果。 On the other hand, when the liquid crystal display according to another embodiment of the present invention is in a "standby state", the aforementioned control unit (not shown) turns off the display control. A switch (not shown) is turned on and a plurality of light source units 321 (i.e., white light-emitting diodes 3211, 3212, 3213, and 3214) are alternately lit at regular intervals. Therefore, the light emitted by the light source unit 321 is intermittently guided by the light guide plate 322 to reach the light guiding convex portion 3222, so that the light guiding convex portion 3222 intermittently presents a "flickering state". It should be noted that in order to balance the aforementioned white light emitting diodes 3211, 3212, 3213, and 3214, the white light emitting diodes 3211, 3212, 3213, and 3214 may be "rotated" at intervals. Thus, the fluorescent indication area 3512 emits "intermittent fluorescence" due to the irradiation of the light. Moreover, in the present embodiment, the fluorescent indicating area 3512 is coated with a fluorescent layer that emits colored fluorescent light. At this time, since no light passes through the light-transmitting indicating area 3523 and reaches the outside, the fluorescent light emitted from the fluorescent indicating area 3512 can be recognized. Thus, as long as the plurality of light source units 321 (ie, the white light-emitting diodes 3211, 3212, 3213, and 3214) are alternately illuminated for a shorter time interval than the luminance half-life of the fluorescent material constituting the aforementioned phosphor layer, the fluorescent indicator region 3512 will continuously emit colored fluorescent light to achieve the effect of "intermittent fluorescence" in which the liquid crystal display according to another embodiment of the present invention is currently in a "standby state".
最後，當本發明另一實施例之液晶顯示器處於一「關機狀態」時，前述之控制單元(圖中未示)便關閉顯示控制開關(圖中未示)並熄滅全部光源單元321。最後，控制單元(圖中未示)再關閉電源控制開關(圖中未示)。如此，即便在一外界光線微弱的環境中，由於節能指示單元35之導光底座351的螢光指示區3512仍可由於外界微量光線的照射而發出「微弱螢光」，而且此時並無其他光線會通過透光指示 區3523而到達外界，所以即便螢光指示區3512所發出的螢光亮度較低，其仍便可被辨識出來。因此，即便處在一外界光線微弱的環境中，前述之節能指示單元35仍可容易發現電源按鈕36位置。 Finally, when the liquid crystal display according to another embodiment of the present invention is in a "off state", the aforementioned control unit (not shown) turns off the display control switch (not shown) and turns off all of the light source units 321. Finally, the control unit (not shown) turns off the power control switch (not shown). In this way, even in an environment where the external light is weak, the fluorescent indication area 3512 of the light guiding base 351 of the energy saving indicating unit 35 can emit "weak fluorescence" due to the irradiation of the external light, and there is no other at this time. Light will pass through the light The area 3523 reaches the outside, so even if the brightness of the fluorescent light emitted by the fluorescent indicating area 3512 is low, it can be recognized. Therefore, even in an environment where the external light is weak, the aforementioned energy saving indicating unit 35 can easily find the position of the power button 36.

The control unit is electrically coupled to the power button, the display control switch, and the power control switch. The light guide plate is disposed on one side of the light source unit, and the light guide plate protrudes from a side of the edge. a light guiding convex portion is provided; the light guiding upper sleeve portion has a light guiding surface and a light guiding periphery extending from the light guiding surface, and the light guiding base has a supporting seat and a protruding portion a fluorescent indicating area of a certain distance of the supporting base; the carrying bottom plate and the face frame are mutually nested and combined, and the backlight module, the liquid crystal display unit, the energy saving indicating unit and the power button are accommodated therebetween; The upper cover portion is correspondingly inserted into the opening, the light guiding surface includes a light indicating area, and the area of the light indicating area is larger than the area of the fluorescent indicating area; the fluorescent indicating area protrudes from the branch The specific distance of the support is adjustable to control the intensity of the fluorescent light emitted by the fluorescent indicator area; Step B: When the power button is pressed, the control unit confirms whether the liquid crystal display is in a boot State, and when the control unit confirms that the liquid crystal display is in the power-on state, the control unit turns on the power control switch and the display control switch and continuously lights all the light source units, and at this time, the energy-saving indicating unit is transmitted through the light-emitting convex portion In the fully illuminated state; Step C: When the control unit detects that there is no synchronization signal on the input terminal, the control unit confirms whether the liquid crystal display is in a standby state, and when the control unit confirms that the liquid crystal display is in the standby state, The control unit turns off the display control switch, and alternately illuminates the light source unit adjacent to one of the light guiding protrusions at a specific time, and at this time, the energy saving indicating unit is in an intermittent light and dark state through the light guiding convex portion; And step D: when the power button is pressed again, the control unit confirms whether the liquid crystal display is in a shutdown State, and when the control unit confirms that the liquid crystal display is in the off state, the control unit turns off the display control switch and turns off all the light source units, and the control unit turns off the power control switch again, and the light guiding convex portion is at no time. The state of the light source, the energy-saving indicating unit can only accept external light sources.
而當執行步驟B時，本發明又一實施例之節能指示方法之步驟A所提供之液晶顯示器的控制單元會先判斷此液晶顯示器是否處於一「開機狀態」，且在確認此液晶顯示器處於一「開機狀態」後，此控制單元便開啟此電源控制開關及此顯示控制開關，並持續地點亮此液晶顯示器之全部 光源單元。如此，前述之光源單元所發出的光線便持續經由導光板的導引而到達引光凸部，使得引光凸部維持一「明亮狀態」。而且，由於液晶顯示器之節能指示單元係設置於引光凸部上，且其導光上套部具有一導光指示面，導光指示面更包含透光指示區，所以前述到達引光凸部的光線便持續地通過透光指示區而到達外界，達到顯示此液晶顯示器目前係處於一「開機狀態」的「省能白光」效果。 When the step B is performed, the control unit of the liquid crystal display provided in step A of the energy saving indicating method according to another embodiment of the present invention first determines whether the liquid crystal display is in a "on state", and confirms that the liquid crystal display is in a After the "on state", the control unit turns on the power control switch and the display control switch, and continuously illuminates all of the liquid crystal display. Light source unit. In this way, the light emitted by the light source unit continues to be guided by the light guide plate to reach the light guiding convex portion, so that the light guiding convex portion maintains a "bright state". Moreover, since the energy-saving indicating unit of the liquid crystal display is disposed on the light guiding convex portion, and the light guiding upper sleeve portion has a light guiding surface, the light guiding indicating surface further includes a light transmitting indicating area, so the foregoing reaching the light guiding convex portion The light continuously reaches the outside through the light-transmitting indication area, and the effect of displaying the liquid crystal display is currently in a "power-saving state".
接著，若此控制單元判斷此液晶顯示器並非處於一「開機狀態」後，控制單元便繼續執行步驟C。此時若此控制單元偵測到輸入端無同步訊號時，此控制單元便判斷液晶顯示器是否處於一「待機狀態」，且在確認此液晶顯示器處於一「待機狀態」後，此控制單元便關閉此顯示控制開關以關閉此液晶顯示單元，並且每隔一特定時間輪流點亮鄰近於此引光凸部其中之一的光源單元。如此，前述之光源單元所發出的光線便間歇地經由導光板的導引而到達引光凸部，使得引光凸部間歇地呈現一「忽明忽暗狀態」。如此，螢光指示區便會因為此一光線的照射而發出「間歇螢光」。而在本液晶顯示器中，螢光指示區佈塗一會發出有色螢光之螢光層。因此，只要光源單元被點亮的時間間隔短於構成前述之螢光層之螢光物質的亮度半衰期，螢光指示區便會持續地發出有色螢光，達到顯示此液晶顯示器目前係處於一「待機狀態」的「間歇螢光」效果。 Then, if the control unit determines that the liquid crystal display is not in a "on state", the control unit continues to perform step C. At this time, if the control unit detects that there is no synchronization signal on the input terminal, the control unit determines whether the liquid crystal display is in a “standby state”, and after confirming that the liquid crystal display is in a “standby state”, the control unit is turned off. The display controls the switch to turn off the liquid crystal display unit, and alternately illuminates the light source unit adjacent to one of the light guiding projections at a specific time. In this way, the light emitted by the light source unit is intermittently guided to the light guiding convex portion through the guiding of the light guide plate, so that the light guiding convex portion intermittently presents a “flickering state”. In this way, the fluorescent indicator area will emit "intermittent fluorescence" due to the irradiation of this light. In the liquid crystal display, the fluorescent indicator area is coated with a fluorescent layer that emits colored fluorescent light. Therefore, as long as the time interval in which the light source unit is illuminated is shorter than the half-life of the luminance of the fluorescent material constituting the fluorescent layer, the fluorescent indicator region continuously emits colored fluorescent light, so that the liquid crystal display is currently in a state of " "Intermittent Fluorescence" effect in standby mode.
但若控制單元判斷此液晶顯示器並非處於一「待機狀態」後，此控制單元便執行步驟D。當此電源按鈕再一次被 按下時，控制單元便在確認此液晶顯示器處於一「關機狀態」後關閉此顯示控制開關並熄滅全部光源單元。最後，此控制單元再關閉此電源控制開關。如此，即便在一外界光線微弱的環境中，由於此液晶顯示器之節能指示單元之導光底座的螢光指示區仍可由於外界微量光線的照射而發出「微弱螢光」，而且此時並無其他光線會通過透光指示區而到達外界，所以即便螢光指示區所發出的螢光亮度較低，其仍便可被辨識出來。因此，即便處在一外界光線微弱的環境中，前述之節能指示單元(如電源指示燈)仍可容易發現電源按鈕位置。 However, if the control unit determines that the liquid crystal display is not in a "standby state", the control unit performs step D. When this power button is once again When pressed, the control unit turns off the display control switch and turns off all the light source units after confirming that the liquid crystal display is in a "off state". Finally, the control unit turns off the power control switch. In this way, even in an environment where the external light is weak, the fluorescent indicator area of the light guiding base of the energy-saving indicating unit of the liquid crystal display can emit "weak fluorescence" due to the exposure of external light, and there is no Other light will reach the outside through the light-indicating area, so even if the fluorescent light emitted by the fluorescent indicating area is low, it can be recognized. Therefore, even in an environment where the external light is weak, the aforementioned energy-saving indicating unit (such as a power indicator) can easily find the position of the power button.
因此，本發明又一實施例之節能指示方法所提供之液晶顯示器僅需將到達其導光板之光線進一步導引至一位於其節能指示單元之下側的引光凸部，即可藉由設置於其節能指示單元之導光上套部之導光指示面的「透光指示區」與導光底座之「螢光指示區」顯示出其所處之狀態(開機狀態、待機狀態或關機狀態)。而且，由於在一外界光線微弱的環境中，前述之螢光指示區仍可由於外界微量光線的照射而發出亮度較低之「微弱螢光」，使得前述之節能指示單元(如電源指示燈)仍可容易發現電源按鈕位置。 Therefore, the liquid crystal display provided by the energy saving indicating method according to another embodiment of the present invention only needs to further guide the light reaching the light guide plate to a light guiding convex portion located on the lower side of the energy saving indicating unit, thereby setting The "light-transmitting indicating area" of the light guiding surface of the light guiding upper portion of the energy-saving indicating unit and the "fluorescent indicating area" of the light guiding base indicate the state (power-on state, standby state or power-off state) ). Moreover, in an environment where the external light is weak, the aforementioned fluorescent indicating area can still emit a "weak fluorescent light" with a low brightness due to the irradiation of a small amount of external light, so that the aforementioned energy saving indicating unit (such as a power indicator light) The power button position is still easy to find.
表1係顯示習知液晶顯示器之狀態指示燈、習知液晶電視之狀態指示燈以及本發明之液晶顯示器之節能指示單元之運作模式的對照表。其中，當習知液晶顯示器分別處於「開機狀態」、「待機狀態」及「關機狀態」時，其狀態指示燈係分別顯示「綠燈」、「橙燈」及「紅燈或暗燈」。 當習知液晶電視分別處於「開機狀態」及「關機狀態」時，其狀態指示燈則分別顯示「綠燈」及「紅燈或暗燈」(液晶電視並未具有「待機狀態」)。因此，不管處於何種狀態，習知液晶顯示器之狀態指示燈及習知液晶電視之狀態指示燈都需持續地點亮，非常消耗能源。 Table 1 is a comparison table showing the operation indicators of the conventional liquid crystal display, the status indicator of the conventional liquid crystal television, and the energy saving indicating unit of the liquid crystal display of the present invention. Among them, when the conventional liquid crystal display is in the "on state", "standby state" and "off state", the status indicators respectively display "green light", "orange light" and "red light or dark light". When the LCD TVs are in the "on state" and "off state" respectively, the status indicators display "green light" and "red light or dark light" respectively (the LCD TV does not have "standby status"). Therefore, regardless of the state, the status indicator of the conventional liquid crystal display and the status indicator of the conventional LCD TV need to be continuously lit, which is very energy-consuming.
另一方面，如表1所示，當本發明之液晶顯示器分別處於「開機狀態」、「待機狀態」及「關機狀態」時，其節能指示單元便分別顯示「省能白光」、「間歇螢光」及「微弱螢光」。而節能指示單元顯示出前述之「省能白光」、「間歇螢光」及「微弱螢光」之裝置與機制，由於已詳細敘述於前，在此便不再贅述。 On the other hand, as shown in Table 1, when the liquid crystal display of the present invention is in the "on state", "standby state" and "off state", the energy saving indicating unit respectively displays "energy saving white light" and "intermittent firefly". Light and "light fluorescing". The energy-saving indicator unit shows the above-mentioned devices and mechanisms of "energy-saving white light", "intermittent fluorescence" and "weak fluorescence". As described in detail above, it will not be described here.
綜上所述，本發明之液晶顯示器無須額外設置一個內含雙色或兩個異色發光二極體以顯示出其所處之狀態(開機狀態或待機狀態)，其僅需將到達其導光板之光線進一步導引至一位於其節能指示單元之下側的引光凸部，便可藉由設置於其節能指示單元之導光上套部之導光指示面的 「透光指示區」以及導光底座之「螢光指示區」，顯示出其所處之開機狀態為「省能白光」或待機狀態為「間歇螢光」。況且，由於無須額外設置前述之一個內含雙色或兩個異色發光二極體，本發明之液晶顯示器可移除前述之一個內含雙色或兩個異色發光二極體的材料成本，更可節省下點亮這些發光二極體所需耗費的能源，即省下點亮其電源指示燈所需的能源。除此之外，由於當本發明之液晶顯示器處於一「關機狀態」時，其節能指示單元之導光底座的螢光指示區仍可因為外界微量光線的照射而發出亮度較低之「微弱螢光」，所以即便在一外界光線微弱的環境中，本發明之液晶顯示器之節能指示單元(如電源指示燈)仍可容易發現電源按鈕位置。 In summary, the liquid crystal display of the present invention does not need to additionally provide a two-color or two-color light-emitting diode to indicate its state (on state or standby state), which only needs to reach its light guide plate. The light is further guided to a light guiding convex portion located on a lower side of the energy saving indicating unit, and the light guiding surface of the light guiding upper cover portion of the energy saving indicating unit can be disposed The "light-transmitting indicator area" and the "fluorescent indicator area" of the light-guiding base indicate that the power-on state is "saving energy white light" or the standby state is "intermittent fluorescent light". Moreover, since it is not necessary to additionally provide one of the foregoing two-color or two-color light-emitting diodes, the liquid crystal display of the present invention can remove the material cost of the foregoing one-color or two-color light-emitting diodes, thereby saving The energy required to illuminate these light-emitting diodes is to save the energy required to illuminate its power indicator. In addition, when the liquid crystal display of the present invention is in a "off state", the fluorescent indicating area of the light guiding base of the energy saving indicating unit can still emit a low brightness "light ray" due to the external light irradiation. Light, so even in an environment where the external light is weak, the power-saving indicating unit (such as a power indicator) of the liquid crystal display of the present invention can easily find the position of the power button.
