- the drive unit 20 applies a ground voltage (zero volts) to the upper electrode 74 and applies a negative voltage to the lower electrode 72.
- the driving unit 20 applies a negative voltage to the upper electrode 74 and applies a negative voltage having a larger value than the upper electrode 74 to the lower electrode 72.
- an electric field E from the upper electrode 74 toward the lower electrode 72 is generated in the display layer 73. Therefore, due to the electric field E input from the lower electrode 72 and the upper electrode 74, a Coulomb force directed from the lower electrode 72 to the upper electrode 74 acts on the second element 73b.
- the first element 73a is not particularly displaced by the electric field E input from the upper electrode 74 and the lower electrode 72. The element 73a is pushed out toward the lower electrode 72. That is, when the above-described voltage is applied to the upper electrode 74 and the lower electrode 72, the display layer 73 performs bright display (for example, white display) in units of pixels during matrix driving.
- the display layer 73 changes (draws) the display in units of microcapsules 73d (units of display pixels 73A) when the first element 73a is displaced due to the magnetic field H input from the pen 30. )be able to. Further, the display layer 73 has a contact surface due to displacement of the charged element of the first element 73a and the second element 73b due to the electric field E input from the lower electrode 72 and the upper electrode 74. The display can be changed for the entire 70A or for each pixel when driving the matrix.
- the effect of the display device 5 will be described.
- the display on the display layer 73 changes due to the electric field E input from the upper electrode 74 and the lower electrode 72. Therefore, when the display on the display layer 73 is erased, the electric field E input from the upper electrode 74 and the lower electrode 72 can be used. For example, by inputting the electric field E to the entire display layer 73, the entire contact surface 70A can be erased at once. In addition, since the contact surface 70A is erased by using the electric field E, it is possible to make it less likely to cause erasure than in the case of erasing using the magnetic field.
- the display on the display layer 73 changes due to the magnetic field H input from the pen 30. Therefore, when drawing on the contact surface 70A, the magnetic field H input from the pen 30 can be used. Here, when the magnetic field H is input from the pen 30, a high-speed response of drawing on the contact surface 70A can be realized. As described above, in the display device 5, when the magnetic field H is used for drawing and the electric field E is used for erasing, it is possible to realize a display device that has both high-speed drawing and collective erasing and hardly causes erasure. .
- the upper electrode 74 and the lower electrode 72 when at least one of the upper electrode 74 and the lower electrode 72 is composed of a plurality of partial electrodes (12 ⁇ / b> A, 14 ⁇ / b> A), the upper electrode 74, the lower electrode 72, The portions facing each other become pixels during matrix driving. Therefore, in a predetermined pixel during matrix driving, when the potential difference between the upper electrode 74 and the lower electrode 72 is larger than the threshold potential difference, only a predetermined region in the contact surface 70A can be erased. . Further, in all the pixels at the time of matrix driving, when the potential difference between the upper electrode 74 and the lower electrode 72 is made larger than the threshold potential difference, the entire contact surface 70A can be erased.
- At least one of the upper electrode 74 and the lower electrode 72 is constituted by a plurality of partial electrodes (12A, 14A), so that the contact surface 70A is partially erased or the entire contact surface 70A is removed. It can be erased at once. Therefore, in this case, it is possible to realize a display device that combines high-speed drawing, collective erasure, and partial erasure, and that hardly causes erasure.
- the coordinate data of the pen 30 or the finger 100 or the drawing data of the pen 30 is generated on the sensor panel X side.
- the presence of the display panel 70 does not get in the way.
- the sensor panel X is electrically shielded, for example, by using a change in capacitance formed between the electrode substrate 11 and the magnetic conductive layer 14 and the conductive layer 12. This is because the position coordinates of the tip of the finger and the tip of the finger 100 are detected.
- the generation of the drawing data and the display on the display panel 70 are synchronized with each other.
- both the generation of the drawing data and the display on the display panel 70 are performed, for example, when the tip of the pen 30 or the tip of the finger 100 contacts the contact surface 70A, the sensor panel X No data is exchanged with the display panel 70. For this reason, it is not necessary to provide a separate circuit for the synchronization, and the circuit configuration of the display device 5 is simplified accordingly.

[構成]
図1は、本技術の第1の実施の形態に係る入力装置1の断面構成の一例を表す。入力装置1は、先端から磁界を発生させるペン30を利用して情報入力を行う装置である。入力装置1は、接触面10Aを有するセンサパネル10と、センサパネル10を駆動すると共にセンサパネル10の出力に基づいて座標データを生成する駆動部20と、ペン30とを備えている。入力装置1は、本技術の「入力装置」の一具体例に相当する。接触面10Aは、本技術の「接触面」の一具体例に相当する。センサパネル10は、本技術の「センサパネル」、「センサ部」の一具体例に相当する。駆動部20は、本技術の「駆動部」の一具体例に相当する。ペン30は、本技術の「ペン」の一具体例に相当する。
ペン30は、上述したように、先端から磁界を発生させる。ペン30は、例えば、ペン30の先端を接触面10Aに近接させたり接触させたりすることにより、ペン30の先端から発せられる磁界(磁力線)を用いて、ペン30の先端の位置情報をセンサパネル10に入力する。ペン30の先端の位置情報には、例えば、接触面10AをXY平面としたときのXY座標データが含まれている。なお、ペン30の先端の位置情報には、さらに、例えば、接触面10Aの法線をZ軸としたときのZ座標データが含まれていてもよい。
センサパネル10は、ペン30の先端から発せられる磁界(磁力線)を静電容量変化で検出する。具体的には、センサパネル10は、接触面10Aもしくはその近傍の磁力を静電容量変化で検出する。センサパネル10は、さらに、静電容量変化に応じた信号を、静電容量変化の生じた位置に関する情報と共に出力可能となっている。センサパネル10は、例えば、電極基板11と、電極基板11の上面側に配置された導電層12および保護層13と、電極基板11の下面側に配置された磁性導電層14とを有している。導電層12が、接触面10Aと電極基板11との間隙に配置され、磁性導電層14が、電極基板11よりも接触面10Aから離れた位置に配置されている。つまり、電極基板11が、導電性を有する2つの層(導電層12および磁性導電層14)によって上下方向から挟み込まれている。導電層12が、本技術の「導電層」の一具体例に相当する。磁性導電層14が、本技術の「磁性層」の一具体例に相当する。
駆動部20は、上述したように、センサパネル10を駆動すると共にセンサパネル10の出力に基づいて座標データを生成する。駆動部20は、例えば、検出回路21と、演算部22と、記憶部23と、出力部24とを有している。
次に、入力装置1の動作について説明する。ユーザがペン30の先端を接触面10Aに近接させるか、または接触させる(図2参照)。すると、ペン30の先端から生じる磁力によって、磁性導電層14が接触面10A側に局所的に浮き上がる。その結果、ペン30の先端部分の下方において、電極基板11と磁性導電層14との距離が短くなり、センサパネル10の静電容量が局所的に減少する。ペン30の先端から生じる磁力によって磁性導電層14が浮き上がる量は、ペン30の先端部分の直下において最も大きくなり、ペン30の先端部分の直下から離れるにつれて小さくなる。
次に、入力装置1の効果について説明する。本実施の形態では、接触面10Aもしくはその近傍の磁力が静電容量変化で検出されることにより、ペン30の先端の位置情報が入力装置1に入力される。従って、磁力による静電容量変化をほとんど生じさせない指や手のひらによる誤動作を抑制することができる。
[変形例A]
図6は、上記実施の形態の入力装置1の断面構成の一変形例を表す。本変形例では、センサパネル10が、電極基板11と導電層12との間に空隙17Aを有し、空隙17Aを維持する複数のスペーサ17を有している。本変形例では、さらに、接触面10Aを構成する保護層13と、導電層12とが可撓性を有し、保護層13および導電層12が、接触面10Aの変形に応じて変形する。空隙17Aは、本技術の「空隙」の一具体例に相当する。スペーサ17は、本技術の「スペーサ」の一具体例に相当する。
図9は、図1の入力装置1の断面構成の一変形例を表す。図10は、ペン30の先端が接触面10Aに接触したときの図9の入力装置1の作用の一例を表す。図11は、図6の入力装置1の断面構成の一変形例を表す。図12は、ペン30の先端が接触面10Aに接触したときの図11の入力装置1の作用の一例を表す。

次に、本実施の形態の入力装置2の動作について説明する。ユーザがペン30の先端を接触面10Aに近接させるか、または接触させる。すると、ペン30の先端から生じる磁力によって、磁性導電層14が電極基板11と共に、接触面10A側に局所的に浮き上がる。その結果、ペン30の先端部分の下方において、電極基板11および磁性導電層14と、導電層12との距離が短くなり、センサパネル40の静電容量が局所的に減少する。ペン30の先端から生じる磁力によって磁性導電層14が浮き上がる量は、ペン30の先端部分の直下において最も大きくなっており、ペン30の先端部分の直下から離れるにつれて小さくなっている。さらに、ユーザがペン30の先端を接触面10Aに押圧すると、導電層12および保護層13が窪む。その結果、ペン30の先端部分の下方において、電極基板11と導電層12との距離がさらに短くなり、センサパネル40の静電容量がさらに減少する。
次に、本実施の形態の入力装置2の効果について説明する。本実施の形態では、上記実施の形態の入力装置1と同様、接触面10Aもしくはその近傍の磁力が静電容量変化で検出されることにより、ペン30の先端の位置情報が入力装置2に入力される。従って、本実施の形態では、上記実施の形態の入力装置1と同様の効果を得ることができる。
[変形例D]
図17は、上記第2の実施の形態の入力装置2の断面構成の一変形例を表す。本変形例では、センサパネル40が、磁性導電層14の代わりに導電層18を備えている。導電層18は、例えば、フィルム上にアルミなどの金属薄膜、カーボン、CNT、ITO、IZO、ナノメタルワイヤ、銀細線などを製膜したもの、または湾曲し得る非磁性の金属プレートやITOガラスなどによって構成されている。導電層18は、電極基板11に固定されており、例えば接着剤などを介して電極基板11に固定されている。さらに、センサパネル40において、各下側電極11Bおよび各上側電極11Dが、導電性の磁性金属(つまり、磁性電極)で構成されており、例えば、SUS(例えば、マルテンサイト系、フェライト系)、鉄、ニッケル、鉄の合金、ニッケルの合金などによって構成されている。従って、本変形例では、各下側電極11Bおよび各上側電極11Dは、磁力の大きさに応じて厚さ方向に局所的に変位する。
次に、本変形例に係る入力装置2の効果について説明する。本変形例では、上記実施の形態の入力装置1と同様、接触面10Aもしくはその近傍の磁力が静電容量変化で検出されることにより、ペン30の先端の位置情報が入力装置2に入力される。従って、本変形例では、上記実施の形態の入力装置2と同様の効果を得ることができる。
図18は、図15の入力装置2の断面構成の一変形例を表す。図19は、図17の入力装置2の断面構成の一変形例を表す。
次に、第1および第2の実施の形態に共通する変形例について説明する。

図25は、本技術の第3の実施の形態の入力装置3の断面構成の一例を表す。本実施の形態では、入力装置3は、入力装置1,2と同様に、先端から磁界を発生させるペン30を利用して情報入力を行う装置である。入力装置3は、接触面10Aを有するセンサパネル50と、センサパネル50を駆動すると共にセンサパネル50の出力に基づいて座標データを生成する駆動部20と、ペン30とを備えている。以下では、上記実施の形態の入力装置1,2の構成と共通する構成についての記述を適宜、省略するものとする。入力装置3は、本技術の「入力装置」の一具体例に相当する。センサパネル50は、本技術の「センサパネル」、「センサ部」の一具体例に相当する。
センサパネル50は、ペン30の先端から発せられる磁界(磁力線)を静電容量変化で検出する。具体的には、センサパネル50は、接触面10Aもしくはその近傍の磁力を静電容量変化で検出する。センサパネル50は、さらに、静電容量変化に応じた信号を、静電容量変化の生じた位置に関する情報と共に出力可能となっている。センサパネル50は、例えば、電極基板11と、電極基板11の上面側に配置された磁性導電層14、剛体層51および保護層13と、電極基板11の下面側に配置された導電層52とを有している。磁性導電層14が、接触面10Aと電極基板11との間隙に配置され、電極基板11よりも接触面10Aに近い位置に配置されている。導電層52が、電極基板11よりも接触面10Aから離れた位置に配置されている。つまり、電極基板11が、導電性を有する2つの層(磁性導電層14および導電層52)によって上下方向から挟み込まれている。磁性導電層14が、本技術の「磁性層」の一具体例に相当する。剛体層51が、本技術の「剛体層」の一具体例に相当する。
駆動部20は、上述したように、センサパネル50を駆動すると共にセンサパネル50の出力に基づいて座標データを生成する。駆動部20は、上記実施の形態と同様に、例えば、検出回路21と、演算部22と、記憶部23と、出力部24とを有している。
次に、入力装置3の動作について説明する。ユーザがペン30の先端を接触面10Aに近接させるか、または接触させる。すると、ペン30の先端から生じる磁力によって、磁性導電層14が接触面10A側に局所的に浮き上がる。その結果、ペン30の先端部分の下方において、電極基板11と磁性導電層14との距離が長くなり、センサパネル50の静電容量が局所的に増加する。ペン30の先端から生じる磁力によって磁性導電層14が浮き上がる量は、ペン30の先端部分の直下において最も大きくなり、ペン30の先端部分の直下から離れるにつれて小さくなる。
次に、入力装置3の効果について説明する。本実施の形態では、上記実施の形態の入力装置1と同様、接触面10Aもしくはその近傍の磁力が静電容量変化で検出されることにより、ペン30の先端の位置情報が入力装置3に入力される。従って、本実施の形態では、上記実施の形態の入力装置1と同様の効果を得ることができる。

図27は、本技術の第4の実施の形態の入力装置4の断面構成の一例を表す。図28は、ペン30の先端および指100の先端が接触面10Aに接触したときの入力装置4の作用の一例を表す。入力装置4は、上記実施の形態の入力装置3において、センサパネル50の代わりにセンサパネル60を設けたものに相当する。そこで、以下では、センサパネル60について主に詳述し、上記実施の形態の入力装置3の構成と共通する構成についての記述を適宜、省略するものとする。入力装置4は、本技術の「入力装置」の一具体例に相当する。センサパネル60は、本技術の「センサパネル」の一具体例に相当する。
次に、入力装置4の効果について説明する。本実施の形態では、上記実施の形態の入力装置1と同様、接触面10Aもしくはその近傍の磁力が静電容量変化で検出されることにより、ペン30の先端の位置情報が入力装置4に入力される。従って、本実施の形態では、上記実施の形態の入力装置1と同様の効果を得ることができる。
次に、第1~第4の実施の形態に共通する変形例について説明する。
第1~第4の実施の形態およびそれらの変形例では、ペン30は、先端に磁石32を有していた。しかし、第1~第4の実施の形態およびそれらの変形例において、例えば、図29に示したように、ペン30が、先端にコイル33を有し、このコイル33に直流電流を供給する電池34を有していてもよい。このようにした場合には、コイル33に直流電流が供給されることにより、コイル33が電磁石となり、電磁石により生じる磁力がセンサパネル10,40,50,60で検出されることにより、ペン30の先端の位置情報を入力装置1,2,3,4に入力することができる。
第1~第4の実施の形態およびそれらの変形例では、ペン30は、先端だけに磁石32を有していた。しかし、第1~第4の実施の形態およびそれらの変形例において、例えば、図31に示したように、ペン30が、先端だけでなく、後端にも磁石32を有していてもよい。このとき、後端に設けられた磁石32の磁極の向きが、先端に設けられた磁石32の磁極の向きと同じになっている。つまり、後端に設けられた磁石32におけるペン30の後端側の磁極が、先端に設けられた磁石32におけるペン30の先端側の磁極と反対となっている。従って、例えば、ペン30の先端を使って磁性導電層14を浮上させた後に、磁性導電層14のうち浮上している箇所を、ペン30の後端を使って強制的に元の位置に戻すことができる。
第1~第4の実施の形態およびそれらの変形例では、磁性導電層14が、導電性の磁性金属で構成されたシート状部材となっている場合が例示されていた。しかし、第1~第4の実施の形態およびそれらの変形例において、例えば、図33に示したように、磁性導電層14が、導電層14Aの表面に磁性層14Bを設けた積層体となっていてもよい。磁性層14Bは、例えば、酸化鉄(III)、クロム酸化鉄、コバルト酸化鉄、または、フェライト酸化鉄などにより構成されている。
第1~第4の実施の形態およびそれらの変形例において、例えば、図34に示したように、磁性導電層14の代わりに、磁性層14Bが用いられていてもよい。このとき、磁性層14Bがフローティング電位となっていてもよい。磁性層14Bがフローティング電位となった場合であっても、接触面10Aもしくはその近傍の磁力を静電容量変化で検出することが可能である。
第1~第4の実施の形態およびそれらの変形例において、磁性導電層14が、磁化された磁性体で構成されているか、または軟磁性体で構成されていてもよい。このようにした場合には、磁性導電層14が徐々に磁化されるなどして、磁性導電層14の特性が径時的に変化するのを防止することができる。
第1~第4の実施の形態およびそれらの変形例において、磁性導電層14または磁性層14Bが、磁性金属で構成されたシート状部材となっている場合が例示されていた。しかし、第1~第4の実施の形態およびそれらの変形例において、例えば、図36に示したように、磁性導電層14全体または磁性層14B全体が、多数の細かな開口の形成されたメッシュ状となっていてもよい。なお、図36には、複数のスペーサ15,16,53または54が行列状に配置されている様子が例示されている。また、図36では、4つのスペーサ15,16,53または54で囲まれた領域に対して、単位センサ領域14aという名称が付与されている。図36には、スペーサ15,16,53または54の位置や、単位センサ領域14aの位置によらず、磁性導電層14全体または磁性層14B全体がメッシュ状となっている様子が例示されている。
[構成]
図41は、本技術の第5の実施の形態の表示装置5の断面構成の一例を表す。本実施の形態では、表示装置5は、第1~第4の実施の形態およびそれらの変形例のセンサパネル10,40,50または60(以下、単に「センサパネルX」と称する。)と、センサパネルXの上面に接して設けられた表示パネル70と、センサパネルXおよび表示パネル70を駆動する駆動部80とを備えている。センサパネルXは、接触面70Aもしくはその近傍の磁力を静電容量変化で検出し、静電容量変化に応じた信号を、静電容量変化の生じた位置に関する情報と共に出力可能となっている。表示装置5は、本技術の「表示装置」の一具体例に相当する。センサパネルXは、本技術の「センサ部」の一具体例に相当する。駆動部80は、本技術の「第1駆動部」、「第2駆動部」の一具体例に相当する。なお、以下では、上記段落において既に言及した内容と重複する内容については適宜、省略するものとする。
表示パネル70は、磁界および電界の変化に応じて表示を変えるものである。図42は、表示パネル70の断面構成の一例を表す。表示パネル70は、可撓性を有している。表示パネル70は、例えば、下側基板71、下側電極72、表示層73、上側電極74および上側基板75を有している。下側基板71および上側基板75は、下側電極72、表示層73および上側電極74を支持するものであり、離間して互いに対向配置されている。表示層73は、磁界および電界の変化に応じて表示を変えるものであり、下側基板71および上側基板75の間隙に配置されている。上側電極74および下側電極72は、表示層73に電界を印加するものであり、表示層73を間にして互いに対向するように配置されている。下側電極72は、下側基板71寄りに配置されており、上側電極74は、上側基板75寄りに配置されている。
駆動部80は、上記実施の形態の駆動部20を含んでおり、具体的には、センサパネルXを駆動すると共に、センサパネルXの出力に基づいて座標データを生成する。駆動部80は、さらに、表示パネル70を駆動する。駆動部80は、表示パネル70に対して電界を印加することにより、表示パネル70の表示を変化させる。具体的には、駆動部80は、表示層73に対して電界を印加することにより、表示パネル70の表示を消去する。
図46は、磁界Hが入力されたときの表示層73の作用の一例を表すものである。上述したように、第1要素73aが磁性体であり、第2要素73bが非磁性体である。そのため、ペン30から入力された磁界Hに起因して、第1要素73aに対して、下側電極72から上側電極74に向かう磁力が働く。その結果、第1要素73aが上側電極74側(または上側基板75側)に変位し、上側電極74に接触ないしは近接する。その一方で、ペン30から入力された磁界Hによって第2要素73bは特段、変位しないが、第1要素73aの、上側電極74近傍への密集に起因して、第2要素73bが下側電極72(または下側基板71側)方向に押し出される。つまり、表示層73は、ペン30が接触面70Aに接触すると、ペン30の接触部分において、暗表示(例えば黒表示)となる。
次に、表示装置5の効果について説明する。表示装置5では、上側電極74および下側電極72から入力される電界Eに起因して、表示層73の表示が変化する。そのため、表示層73の表示を消去する際には、上側電極74および下側電極72から入力される電界Eを利用することができる。例えば、電界Eを表示層73全体に入力することにより、接触面70A全面を一度に消去することができる。しかも、接触面70Aの消去を、電界Eを利用して行うので、磁界を利用した消去の場合よりも、消去残しを生じ難くすることができる。
[構成]
図50は、本技術の第6の実施の形態に係る表示装置6の断面構成の一例を表すものである。表示装置6は、上記実施の形態の表示装置6において、表示パネル70の代わりに表示パネル90を設け、さらに、駆動部80の代わりに駆動部110を設けたものに相当する。そこで、以下では、表示パネル90および駆動部110について主に詳述し、上記段落において既に言及した内容と重複する内容については適宜、省略するものとする。
次に、表示装置6の効果について説明する。表示装置6では、ペン30の描画データを、表示パネル90の表示にリアルタイムに追記することができ、さらに、追記により生成された新たなデータが記憶部23に格納される。これにより、ユーザは、表示パネル90に追記をすることができるだけでなく、追記したデータを記憶部23に保存することもできる。
図54は、表示装置6の断面構成の一変形例を表す。例えば、図54に示したように、表示パネル90の接触面90Aが、ペン30で情報を入力するペン入力領域90aと、指で情報を入力する指入力領域90bとに分割されていてもよい。このようにした場合には、例えば、ユーザが、ペン入力領域90aに指や手のひらを載せた状態でペン30を操作した場合に、指や手のひらが誤検出されるのを防止することができる。
