技术领域 FIELD

本实用新型涉及一种显示器,特别是涉及一种利用发光二极管的显示器。 The present invention relates to a display, particularly to a display utilizing light emitting diode.

背景技术 Background technique

现代人在日常生活中几乎无时无刻与电器用品相处在一起,而当这些电器用品需要显示数字或文字来传递讯息时,往往因为背景光线的因素,导致不易观察而影响判读结果。 Almost all the time to get along together with modern appliances in their daily lives, and when these appliances need to display a number or text message to deliver, often because of factors that background light, leading to affect the interpretation of the results difficult to observe. 举例来说,实验人员在实验室进行数据量测时,如果不论背景亮暗程度,电子仪器的显示面板上的数字亮度皆相同,那么当背景亮度大于数字亮度时,往往无法在强亮度的背景下清楚辨识暗亮度的数字,可能会影响到实验人员判读结果。 For example, laboratory personnel for measuring the amount of data, if the digital luminance regardless of background light or dark, an electronic instrument display panel are the same, then the number is greater than when the brightness of the background luminance, often can not strong background brightness in the laboratory under the brightness of dark figures clearly identified, it may affect the interpretation of the results of laboratory personnel.

另一方面,电子仪器所显示的数字亮度皆相同,即表示电子仪器持续使用相同额定电流来驱动显示面板上的数字发光。 On the other hand, the digital luminance of the displayed electronic equipment are the same, it means that electronic devices continue to use the same number of rated current to drive the light emitting display panel. 然而,当背景亮度小于数字亮度时,实验人员可清楚地观察所欲量测的数值,即并不需要使用如此大的额定电流来驱动显示面板上的数字发光。 However, when the background luminance is less than the digital luminance experimenter clearly observed values ​​of measurement desired, i.e., not necessary to use such a large number of rated current to drive the light emitting display panel. 此时,电子仪器应可使用较小的电流值来驱动显示面板上的数字发光,即可达到令实验人员能清楚观察数据的目的。 At this time, the electronic equipment should be used to drive a small current value of the digital display on the light emitting panel, can achieve the purpose of the art can be clearly observed in experimental data.

图1是本实用新型一较佳实施例的发光二极管显示器的方块图。 FIG. 1 is a block diagram of the present invention, a light emitting diode display according to the preferred embodiment. 而此发光二极管显示器的上视图,如图2所示。 And the upper view of this light emitting diode display, as shown in FIG.

请同时参阅图1及图2所示。 Please also refer to FIG. 1 and FIG. 2 FIG. 在图1的发光二极管显示器106中,放大器102电性连接于感光元件100以及发光二极管104。 In the light emitting diode display 106 of FIG. 1, the amplifier 102 is electrically connected to the photosensitive member 100 and the light emitting diode 104. 而感光元件100与发光二极管104安装在显示面版108的同一侧(如图2所示)。 The photosensitive member 100 and the light emitting diode 104 is mounted on the same side (FIG. 2) of the display surface 108 version. 感光元件100感应背景亮度,并依背景亮度产生一调控电流。 Photosensitive element 100 senses the brightness of the background, and the background luminance produced by a current regulation. 此调控电流将输入放大器102,并经由放大器102放大。 This regulation of the input current amplifier 102, and amplified by the amplifier 102. 放大后的调控电流将用来调控发光二极管104的亮度。 Amplified current regulation for regulation of the brightness of the LED 104.

接下来,请参阅图3所示,其为本实用新型一较佳实施例的发光二极管显示器的电路图。 Next, please refer to FIG. 3, which is a circuit diagram of light emitting diode display according to a preferred embodiment of the novel present invention. 将藉由此电路图,进一步说明,发光二极管显示器的内部运作。 With this circuit diagram will be further described, the internal light emitting diode display operation. 感光元件300感测背景亮度后,感光元件300的电阻将改变。 After the photosensitive element 300 senses the brightness of the background, the resistance of the photosensitive element 300 will change. 而此电阻与背景亮度成正相关。 This resistance while a positive correlation with the background luminance. 即当背景亮度大时,电阻即变大;而当背景亮度小时,电阻即变小。 That is, when the background brightness, i.e., resistance increases; hours when background brightness, i.e., the resistance becomes small.

外接电源提供整个电路一固定电压,若感光元件300感测背景亮度后,感光元件300的电阻变大,一电流在P点分流时,通过第一路径301的电流将大于第二路径302的电流。 External power supply provides a fixed voltage throughout the circuitry, the brightness of the background 300 senses if the photosensitive member, the resistance of the photosensitive member 300 becomes larger, a current shunt when the point P, the current 301 through the first path will be greater than the second current path 302 . 接着,这通过第一路径301的电流成为一调控电流,如果此调控电流皆大于第一电晶体303的内设值及第二电晶体304的内设值,则调控电流经过第一电晶体303及第二电晶体304的放大,将成为一放大的调控电流,用以增益发光二极管305的亮度。 Then, it becomes a regulated current of the first current path 301 through, if this regulation are greater than the current value of the first transistor 303 and a second site electrically site of the crystal 304, the regulation current through the first transistor 303 and second amplifying transistor 304 will become a regulatory amplified current to the light emitting diode luminance gain 305.

同样的,外接电源提供整个电路一固定电压,若感光元件300感测背景亮度后,感光元件300的电阻变小,一电流在P点分流时,通过第一路径301的电流将小于第二路径302的电流。 Similarly, the external power supply provides a fixed voltage throughout the circuitry, the brightness of the background 300 senses if the photosensitive member, the resistance of the photosensitive member 300 becomes smaller, a point P when the shunt current, the current through the first path 301 is smaller than the second path 302 current. 接着,这通过第一路径301的电流成为一调控电流,如果此调控电流小于第一电晶体303的内设值或第二电晶体304的内设值,则调控电流将无法通过第一电晶体303或第二电晶体304。 Then, it becomes a regulated current of the current 301 through the first path, if this current is less than a first electrical site regulation of the crystal 303 or a second electrical features of the crystal 304, the regulation current through the first transistor will not second transistor 303 or 304. 如此一来,此调控电流将不对发光二极管305的亮度进行增益。 Thus, this regulation of current brightness of the light emitting diode 305 will not be gain.

另外,因为每一个感光元件300的电阻各有差异,所以将一可变电阻306电性连接于感光元件300与外接电源307之间,以供调整感光元件300的敏感度。 Further, since the difference in the resistor 300 each have a photosensitive element, the variable resistor 306 is electrically connected to a photosensitive member 300 between the external power source 307, for adjusting the sensitivity of the photosensitive member 300. 若希望感光元件300的敏感度高,则将可变电阻306调小;若希望感光元件300的敏感度低,则将可变电阻306调大。 If desired the photosensitive member 300 is a high sensitivity, small adjustments are being variable resistor 306; if desired the low sensitivity of the photosensitive member 300, a variable resistor 306 will be major.

由上述本实用新型较佳实施例可知,不论背景亮度亮或暗,都可以藉由感光元件的调节,适当地调控发光二极管的亮度。 Utility of the present embodiment seen from the new preferred embodiment, whether light or dark background luminance, the photosensitive member can be adjusted by appropriately regulate the brightness of the light emitting diode. 因此使用者观察此发光二极管显示器时,比较不易因背景亮度的因素造成判读错误。 Therefore, when the user observe this light emitting diode display, less prone to error due to factors resulting in the interpretation of the background brightness. 而且,当背景亮度太暗时,因为感光元件可以调控流经发光二极管的电流减少,所以可以减少能量的损耗,并且延长发光二极管的寿命。 Further, when the brightness of the background dark, because the photosensitive member can be regulated to reduce the current flowing through the light emitting diode, energy loss can be reduced, and extend the life of the light emitting diode.

以上所述,仅是本实用新型的较佳实施例而已,并非对本实用新型作任何形式上的限制,虽然本实用新型已以较佳实施例揭露如上,然而并非用以限定本实用新型,任何熟悉本专业的技术人员,在不脱离本实用新型技术方案范围内,当可利用上述揭示的技术内容作出些许更动或修饰为等同变化的等效实施例,但凡是未脱离本实用新型技术方案的内容,依据本实用新型的技术实质对以上实施例所作的任何简单修改、等同变化与修饰,均仍属于本实用新型技术方案的范围内。 The above are only preferred embodiments of the present invention embodiments only, not a limitation on the present invention any form, although the present invention has been described by reference to preferred embodiments, but not intended to limit the present disclosure, any Those skilled in the art, without departing from the present invention within the scope of the technical solution, when some minor modifications may be made using the techniques disclosed content of modification or equivalent change in equivalent embodiments, but all without departing from the technical solution of the present invention content, according to the technical spirit of the present invention is a simple modification of any of the above embodiments made equivalent changes and modifications as would fall within the scope of the technical solution of the present invention.
