Night display is made possible by combining a self-luminous light source with a display using an electrophoretic display element.
An LED 306 is combined with a display element 301 of an electronic paper display device composed of an electrophoretic display element (EPD), and the corresponding display element is illuminated and displayed.

Description

本考案は、電気泳動表示ユニットおよびLED表示ユニットから構成され、電気泳動表示素子(EPD)により構成された電子ペーパ様表示装置にLED発光光源を配置することにより、日中は電気泳動表示素子(EPD)によって表示を行い、輝度が足りないときはLEDを使用してデータを表示することができる高効率電子表示装置に関する。 The present invention is composed of an electrophoretic display unit and an LED display unit, and by arranging an LED light source on an electronic paper-like display device configured by an electrophoretic display element (EPD), an electrophoretic display element ( The present invention relates to a high-efficiency electronic display device capable of performing display by EPD) and displaying data using LEDs when luminance is insufficient.

電気泳動表示素子(EPD)(或いは電子ペーパE‐PAPERと称す)は最近徐々に成熟してきた電子表示設備であり、主な特徴としては、消費電力が極めて少ない、超薄型(0.1mm)、電源の切断後も一定期間表示内容を維持できる、自発光式でない、ことなどが挙げられる。消費電力が極めて少ないという特性をデータ表示設備上に使用した場合、非常に有益であり、例えば、交通情報表示装置などの設備において、電池を使用して操作を行ない、その他の電源を必要としないことによって、大きなコストダウンを図ることが可能である。この点においては従来のLED表示装置と比較できないほど優れている。さらに、電気泳動表示素子(EPD)から構成される表示設備は非常に薄くて軽いので、設置場所に対する負担も少ない。 The electrophoretic display element (EPD) (or electronic paper E-PAPER) is an electronic display facility that has been gradually matured recently. Its main feature is that it consumes very little power and is ultra-thin (0.1 mm). The display content can be maintained for a certain period even after the power is turned off, and it is not self-luminous. It is very beneficial to use the characteristic that power consumption is extremely low on a data display facility. For example, in a facility such as a traffic information display device, operation is performed using a battery, and no other power source is required. As a result, it is possible to greatly reduce the cost. In this respect, it is superior to a conventional LED display device. Further, since the display equipment composed of the electrophoretic display element (EPD) is very thin and light, the burden on the installation place is small.

しかし、電気泳動表示素子(EPD)から構成される表示設備の最大の弱点は自発光式でない点にあり、夜になるとその機能を発揮できない。仮にその他の光源を使用した場合、元来有する消費電力が少ないという長所を失ってしまい、従って、現在電気泳動表示素子(EPD)から構成される表示設備の使用場所は一部制限を受けざるを得ない。 However, the greatest weakness of display equipment composed of electrophoretic display elements (EPDs) is that they are not self-luminous, and cannot function at night. If other light sources are used, the original advantage of low power consumption is lost. Therefore, the use place of the display equipment composed of the current electrophoretic display element (EPD) is subject to some restrictions. I don't get it.

特開2002−40489号公報
The inventor of the present invention has long been involved in the research and development and manufacture of electronic display equipment, has a deep understanding of the principles of various display equipment, and maximizes the excellent features of electrophoretic display elements (EPD). Devised the present invention.
Japanese Patent Laid-Open No. 2002-40489

本考案は、電気泳動表示ユニットおよびLED表示ユニットから構成され、電気泳動表示素子(EPD)により構成された電子ペーパ状の表示装置にLED発光源を組合わせることにより、日中は電気泳動表示素子(EPD)によって表示を行い、輝度が足りないときはLEDを使用してデータを表示することができる高効率電子表示装置を提供することにある。 The present invention is composed of an electrophoretic display unit and an LED display unit, and an electroluminescent display element is combined with an electroluminescent display element (EPD) in combination with an LED light emission source. An object of the present invention is to provide a high-efficiency electronic display device capable of displaying data using (EPD) and displaying data using LEDs when luminance is insufficient.

上述の課題を解決するために、請求項1の考案は、電気泳動表示ユニットと、上下電極、LED,LED搭載回路板から構成されるLED表示ユニットとが組合されて構成される表示装置であり、その実施方式は、電気泳動表示ユニット上に孔を設けてLEDを露出させることを特徴とする高効率電子表示装置である。   In order to solve the above-described problems, the invention of claim 1 is a display device configured by combining an electrophoretic display unit and an LED display unit composed of upper and lower electrodes, LEDs, and LED-mounted circuit boards. The implementation method is a high-efficiency electronic display device in which a hole is provided on the electrophoretic display unit to expose the LED.

請求項2の考案は、LED表示ユニット中のLEDを搭載するLED搭載回路基板には、同時にすべての制御駆動電子素子が設置されることを特徴とする請求項1記載の高効率電子表示装置である。   The invention according to claim 2 is the high-efficiency electronic display device according to claim 1, wherein all the control drive electronic elements are simultaneously installed on the LED-mounted circuit board on which the LEDs in the LED display unit are mounted. is there.

本考案は、電気泳動表示素子(EPD)から構成される表示装置とLED表示装置とを組合せ、日中は電気泳動表示素子(EPD)によってデータの表示を行い、夜間はLEDの発光を利用して電気泳動表示素子(EPD)の表示内容を照射するというものである。夜間においてLEDが必要な輝度は日中の十分の一であるので、すべてLEDから構成される表示装置と比較した場合、使用されるLEDの数量および関連部材は十分の一しか必要でなく、その差は非常に大きい。また、夜間において、LEDは表示が必要な一部を照射すればよく、光源を外設して電気泳動表示素子(EPD)を照射する方式と比較した場合、50%〜80%の電力を節約できる。また、LEDは電気泳動表示素子(EPD)が表示する区域のLEDのみが発光すればよく、表示点でないLEDは発光せず、お互いが構成する高コントラストによってもLEDの輝度は節約できる。従って、本考案と従来技術によるLED表示装置とを比較した場合、本考案の高効率電子表示装置は十分の一のLED数量および関連部材でよく、その重量の差も非常に大きい。 The present invention combines a display device composed of an electrophoretic display element (EPD) and an LED display device, displays data by an electrophoretic display element (EPD) during the day, and uses light emission of the LED at night. The display content of the electrophoretic display element (EPD) is irradiated. Since the brightness required for LEDs at night is one-tenth of the daytime, when compared to a display device consisting entirely of LEDs, only one-tenth of the number of LEDs used and related components are required. The difference is very large. Also, at night, the LED only needs to irradiate a part that needs to be displayed, and saves 50% to 80% of power when compared with a method in which an electrophoretic display element (EPD) is irradiated with an external light source. it can. Further, only the LED in the area displayed by the electrophoretic display element (EPD) needs to emit light, and the LED that is not the display point does not emit light, and the brightness of the LED can be saved also by the high contrast formed by each other. Therefore, when the present invention is compared with the LED display device according to the prior art, the high-efficiency electronic display device of the present invention may be a sufficient number of LEDs and related members, and the difference in weight is very large.

本考案の目的、特徴および効果を示す実施例を図に沿って詳細に説明する。 Embodiments showing the objects, features, and effects of the present invention will be described in detail with reference to the drawings.

本装置は、小型で細かい表示設備には適用されない。一般的に、表示点が10mm以上が好ましいが、小さい表示点の表示設備も本考案に含まれる。 This device is not applicable to small and fine display equipment. In general, the display point is preferably 10 mm or more, but display equipment having a small display point is also included in the present invention.

図3は、本考案による電気泳動表示素子(EPD)にLEDを加えた高効率電子表示装置を示す断面図である。図から分かるように、本考案の全体のシステムは電気泳動表示ユニット(EPD)301、上下電極302、303、LED306、LED搭載回路基板304および制御駆動電子素子305から構成され、電気泳動表示ユニット301は極めて小さい密封セル(0.1mm以下)から構成される。 FIG. 3 is a cross-sectional view showing a high-efficiency electronic display device in which an LED is added to an electrophoretic display device (EPD) according to the present invention. As can be seen from the figure, the entire system of the present invention comprises an electrophoretic display unit (EPD) 301, upper and lower electrodes 302 and 303, LED 306, LED-mounted circuit board 304, and control drive electronic element 305. Is composed of extremely small sealed cells (0.1 mm or less).

従って、表示フィルム上に電気泳動表示ユニット301、上下電極302、303を構成し、孔を設けてLED306を露出させることは困難なことではなく、LED306を搭載するLED搭載回路板304にはすべての制御駆動電子素子305を設置できる。装置全体のシステムは非常に簡潔であるが、その効率は非常に高い。図4は本考案による電気泳動表示素子(EPD)にLEDを加えた高効率電子表示装置が文字を表示する状態を示す模式図である。 Therefore, it is not difficult to form the electrophoretic display unit 301 and the upper and lower electrodes 302 and 303 on the display film, and to expose the LED 306 by providing a hole. Control drive electronics 305 can be installed. The entire system is very simple, but its efficiency is very high. FIG. 4 is a schematic view showing a state in which a high-efficiency electronic display device in which an LED is added to an electrophoretic display element (EPD) according to the present invention displays characters.
