Description

本発明の実施形態は、表示装置に関する。 Embodiments of the present invention relate to display devices.

近年、一方の面から反対側の他方の面側の背景を視認可能な、いわゆる透明液晶表示パネルを用いた表示装置が提案されている。透明液晶表示パネルは、光透過性を有する第１基板と、光透過性を有し第１基板に対向して配置された第２基板と、第１基板と第２基板との間に封入される高分子分散型の液晶層と、を有している。透明液晶表示パネルに光を入射させる光源あるいは発光部は、第１基板あるいは第２基板の一側面（端縁）と対向して配置され、この一側面に光を入射させる。一般に、光源としてのＬＥＤおよび導光板は、第１基板と第２基板との段差部に配置され、第２基板の側面（端縁）の光を照射する。 In recent years, a display device using a so-called transparent liquid crystal display panel has been proposed, in which the background on the other side of the other side can be visually recognized from one side. The transparent liquid crystal display panel is enclosed between the first substrate having light transmission, the second substrate having light transmission and arranged facing the first substrate, and the first substrate and the second substrate. It has a polymer-dispersed liquid crystal layer. A light source or a light emitting unit that causes light to enter the transparent liquid crystal display panel is arranged so as to face one side surface (edge) of the first substrate or the second substrate, and the light is incident on this one side surface. Generally, the LED and the light guide plate as the light source are arranged at the step portion between the first substrate and the second substrate, and irradiate the light on the side surface (edge) of the second substrate.

上記構成の表示装置において、発光効率を良くするため、ＬＥＤは第２基板およびカバーガラスの厚みと同等の寸法のものを用いる必要がある。すなわち、ＬＥＤは寸法の制約があり、ＬＥＤの選択枝が少なく、高輝度化が難しい。
また、透明液晶表示パネルを複数枚重ねて用いる場合、光源（ＬＥＤ）を第１基板の一端縁から離れた位置に配置する必要があり、この場合、第１基板の一端縁と第２基板の一端縁とは、光源からの距離が相違している。そのため、各透明表液晶示パネルにおいて輝度ムラが発生する要因となる。また、複数の透明液晶表示パネルが別々の色で発光する、いわゆる色割れが発生するおそれがある。
ここで述べる実施形態の課題は、輝度ムラ、色割れの発生を防止し表示品位の向上した表示装置を提供することにある。 In the display device having the above configuration, in order to improve the luminous efficiency, it is necessary to use LEDs having the same dimensions as the thickness of the second substrate and the cover glass. That is, the LED has dimensional restrictions, there are few LED options, and it is difficult to increase the brightness.
Further, when a plurality of transparent liquid crystal display panels are stacked and used, it is necessary to arrange the light source (LED) at a position away from one end edge of the first substrate. In this case, one end edge of the first substrate and the second substrate The distance from the light source is different from the one-end edge. Therefore, it causes uneven brightness in each transparent liquid crystal display panel. In addition, a plurality of transparent liquid crystal display panels may emit light in different colors, so-called color cracking may occur.
An object of the embodiment described here is to provide a display device having improved display quality by preventing the occurrence of luminance unevenness and color cracking.

実施形態に係る表示装置は、光透過性を有する第１基板と、光透過性を有し前記第１基板に対向して配置された第２基板と、前記第１基板と第２基板との間に封入された光拡散性を有する液晶層と、をそれぞれ有し、主面同士を重ねて配置された複数枚の液晶表示パネルと、前記複数枚の液晶表示パネルの前記主面と交差する一側面に対向して配置され、前記一側面に向けて光を出射する発光素子と、前記複数枚の液晶表示パネルの一側面と前記発光素子との間に配置され、前記発光素子から出射された光を拡散する拡散部材と、を備えている。 The display device according to the embodiment includes a first substrate having light transmittance, a second substrate having light transmittance and arranged to face the first substrate, and the first substrate and the second substrate. A plurality of liquid crystal display panels having a light-diffusing liquid crystal layer enclosed between them and having main surfaces overlapped with each other intersect with the main surface of the plurality of liquid crystal display panels. A light emitting element that is arranged to face one side surface and emits light toward the one side surface, and is arranged between one side surface of the plurality of liquid crystal display panels and the light emitting element, and is emitted from the light emitting element. It is provided with a diffuser member that diffuses the light.

表示パネル３０と第１プリント回路基板２２ＡおよびＬＥＤ２４との配置関係について詳細に説明する。
図４は、表示パネルと第１プリント回路基板およびＬＥＤとの配置関係を示す斜視図、図５は、上記配置関係を示す平面図、図６は、上記配置関係を示す側面図である。図７は、液晶表示パネルを概略的に示す断面図である。
始めに、表示パネル３０の構成について説明する。図４に示すように、表示パネル３０は、互いに重ねて配置された複数枚、例えば、３枚の液晶表示パネル３０Ａ、３０Ｂ、３０Ｃを含んでいる。図７に示すように、液晶表示パネルの各々、例えば、液晶表示パネル３０Ａは、矩形状の第１基板ＳＵＢ１と、第１基板ＳＵＢ１に対向配置された矩形状の第２基板ＳＵＢ２と、第１基板ＳＵＢ１と第２基板ＳＵＢ２との間に封入された液晶層ＬＱと、を備えている。第１基板ＳＵＢ１および第２基板ＳＵＢ２は、それぞれガラス板あるいは樹脂板等の光透過性を有する絶縁基板により形成されている。第２基板ＳＵＢ２の周縁部は、シール材ＳＥにより第１基板ＳＵＢ１に貼り合わされている。 The arrangement relationship between the display panel 30, the first printed circuit board 22A, and the LED 24 will be described in detail.
FIG. 4 is a perspective view showing the arrangement relationship between the display panel, the first printed circuit board, and the LED, FIG. 5 is a plan view showing the arrangement relationship, and FIG. 6 is a side view showing the arrangement relationship. FIG. 7 is a cross-sectional view schematically showing a liquid crystal display panel.
First, the configuration of the display panel 30 will be described. As shown in FIG. 4, the display panel 30 includes a plurality of, for example, three liquid crystal display panels 30A, 30B, and 30C arranged so as to be overlapped with each other. As shown in FIG. 7, each of the liquid crystal display panels, for example, the liquid crystal display panel 30A, has a rectangular first substrate SUB1 and a rectangular second substrate SUB2 arranged to face the first substrate SUB1. A liquid crystal layer LQ enclosed between the substrate SUB1 and the second substrate SUB2 is provided. The first substrate SUB1 and the second substrate SUB2 are each formed of a light-transmitting insulating substrate such as a glass plate or a resin plate. The peripheral edge of the second substrate SUB2 is attached to the first substrate SUB1 by the sealing material SE.

第１基板ＳＵＢ１は矩形状の第１主面（外表面）ＭＳ１および第１主面ＭＳ１と交差する長辺側の一対の側面、短辺側の一対の側面ＳＳ１、ＳＳ２とを有している。第２基板ＳＵＢ２は矩形状の第２主面（外表面）ＭＳ２および第２主面ＭＳ２と交差する長辺側の一対の側面、短辺側の一対の側面ＳＳ３、ＳＳ４とを有している。
図示した例では、第２基板ＳＵＢ２は、第１基板ＳＵＢ１とほぼ同一の幅および第１基板ＳＵＢ１の長さよりも短い長さに形成されている。貼り合わせた状態において、第１基板ＳＵＢ１の長手方向の一端部および他端部は、それぞれ第２基板ＳＵＢ２の短辺よりも外側に突出している。幅方向においては、第２基板ＳＵＢ２の一対の長辺は、第１基板ＳＵＢ１の一対の長辺とほぼ面一に整列している。
液晶層ＬＱは、第１基板ＳＵＢ１と第２基板ＳＵＢ２との間のセルギャップにおいて、シール材ＳＥによって囲まれた内側に保持されている。液晶層ＬＱは、光拡散性を有する液晶層であり、一例として、高分子分散型の液晶層を用いている。 The first substrate SUB1 has a rectangular first main surface (outer surface) MS1 and a pair of side surfaces on the long side and SS1 and SS2 on the short side that intersect with the first main surface MS1. .. The second substrate SUB2 has a rectangular second main surface (outer surface) MS2, a pair of side surfaces on the long side intersecting with the second main surface MS2, and a pair of side surfaces SS3 and SS4 on the short side. ..
In the illustrated example, the second substrate SUB2 is formed to have substantially the same width as the first substrate SUB1 and a length shorter than the length of the first substrate SUB1. In the bonded state, one end and the other end in the longitudinal direction of the first substrate SUB1 project outward from the short side of the second substrate SUB2, respectively. In the width direction, the pair of long sides of the second substrate SUB2 are substantially flush with the pair of long sides of the first substrate SUB1.

液晶表示パネル３０Ａは、第１基板ＳＵＢ１側から第２基板ＳＵＢ２の背景を視認可能な、いわゆる透明液晶表示パネルを構成している。画素電極ＰＥに電圧を印加した状態で、一側面ＳＳ１、ＳＳ３側から液晶表示パネル３０Ａに光が入射すると、この入射光は、電圧が印加された領域の液晶分子により反射、拡散され、第１基板ＳＵＢ１の第１主面ＭＳ１側および第２基板ＳＵＢ２の第２主面ＭＳ２側に出射する。これにより、液晶表示パネル３０Ａの両面に、画素電極ＰＥのパターンに対応する画像が表示される。
なお、本実施形態の液晶表示パネルは画素電極自体が図案化あるいは文字化されており、当該画素電極と共通電極間に電圧を印可することで当該図案や文字が表示されるいわゆるパッシブタイプの液晶表示パネルが採用されている。なお、かかる構成とは異なり、複数の画素電極を表示領域上にマトリクス上に配置すると共に当該画素電極ごとにスイッチング素子を設け、各スイッチング素子を個別にオン／オフすることで画像を表示するアクティブタイプの液晶表示パネルを採用することも可能である。
液晶表示パネル３０Ｂ、３０Ｃは、上述した液晶表示パネル３０Ａと同一の寸法および同一の構成を有している。液晶表示パネル３０Ｂ、３０Ｃにおいて、画素電極ＰＥは、液晶表示パネル３０Ａの配列パターンとはそれぞれ異なる配列パターン、例えば、文字列、図柄に形成されている。あるいは、液晶表示パネル３０Ｂ、３０Ｃにおいて、画素電極ＰＥは、液晶表示パネル３０Ａの配列パターンと同一の配列パターンとしてもよい。また、パッシブタイプの液晶表示パネルとアクティブタイプの液晶パネルとを組み合わせる構成も採用可能である。 The liquid crystal display panel 30A constitutes a so-called transparent liquid crystal display panel in which the background of the second substrate SUB2 can be visually recognized from the first substrate SUB1 side. When light is incident on the liquid crystal display panel 30A from one side surface SS1 and SS3 side while a voltage is applied to the pixel electrode PE, the incident light is reflected and diffused by the liquid crystal molecules in the region where the voltage is applied, and the first The light is emitted to the first main surface MS1 side of the substrate SUB1 and the second main surface MS2 side of the second substrate SUB2. As a result, images corresponding to the pattern of the pixel electrode PE are displayed on both sides of the liquid crystal display panel 30A.

Here, the first substrate SUB1 of the liquid crystal display panel 30B faces the second substrate SUB2 of the liquid crystal display panel 30A, and the first substrate SUB1 of the liquid crystal display panel 30C faces the second substrate SUB2 of the liquid crystal display panel 30B. ing. Both side surfaces on the long side and both side surfaces on the short side of the three first substrates SUB1 are arranged substantially flush with each other. The three liquid crystal display panels 30A, 30B, and 30C are held in a state of overlapping and facing each other by supporting and holding one end and the other end in the longitudinal direction by the main body 14 and the cap 42 described above. In the present embodiment, these three liquid crystal display panels 30A, 30B, and 30C are merely arranged so as to overlap each other, and no adhesive or the like is provided between them. It is also possible to adopt a configuration in which an adhesive is provided between these to bond the liquid crystal display panels to each other.

表示パネル３０は、第１プリント回路基板２２Ａに対してほぼ垂直に配置されている。３枚の第１基板ＳＵＢ１の短辺側の一側面ＳＳ１は、第１プリント回路基板２２Ａの第１主面ＳＡ１に隙間を置いてほぼ平行に対向している。同様に、３枚の第２基板ＳＵＢ２の短辺側の一側面ＳＳ３は、第１主面ＳＡ１に隙間を置いてほぼ平行に対向している。
第１主面ＳＡ１上に実装された２つのＬＥＤ２４は、表示パネル３０の幅方向に互いに間隔を置いて配置され、それぞれ３枚の第１基板ＳＵＢ１の一側面ＳＳ１および３枚の第２基板ＳＵＢ２の一側面ＳＳ３に対向している。 The display panel 30 is arranged substantially perpendicular to the first printed circuit board 22A. One side surface SS1 on the short side side of the three first substrate SUB1 faces substantially parallel to the first main surface SA1 of the first printed circuit board 22A with a gap. Similarly, the one side surface SS3 on the short side side of the three second substrates SUB2 faces each other substantially in parallel with a gap on the first main surface SA1.
The two LEDs 24 mounted on the first main surface SA1 are arranged so as to be spaced apart from each other in the width direction of the display panel 30, respectively, one side surface SS1 of the three first substrate SUB1 and the three second substrate SUB2. It faces SS3 on one side.

本実施形態によれば、表示パネル３０の一側面とＬＥＤ２４との間に拡散部材が配置されている。一例では、拡散部材として、乳白色のシリコンゴムで形成された拡散シートＤＳを用いている。拡散シートＤＳは矩形状に形成され、表示パネル３０の幅よび厚さよりも大きい寸法を有している。これにより、拡散シートＤＳは、３枚の第１基板ＳＵＢ１の一側面ＳＳ１および３枚の第２基板ＳＵＢ２の一側面ＳＳ３の全体と対向しているとともに、２つのＬＥＤの発光面全体を覆っている。 According to this embodiment, a diffusion member is arranged between one side surface of the display panel 30 and the LED 24. In one example, a diffusion sheet DS made of milky white silicone rubber is used as the diffusion member. The diffusion sheet DS is formed in a rectangular shape and has a size larger than the width and thickness of the display panel 30. As a result, the diffusion sheet DS faces the entire side surface SS1 of the three first substrate SUB1 and the entire side surface SS3 of the three second substrate SUB2, and covers the entire light emitting surface of the two LEDs. There is.

上記構成の表示装置１０では、ＬＥＤ２４から出射された光は、拡散シートＤＳを通り拡散された後、表示パネル３０の一側面、すなわち、３枚の第１基板ＳＵＢ１の一側面ＳＳ１および３枚の第２基板ＳＵＢ２の一側面ＳＳ３に入射する。入射した光は、液晶層ＬＱの電圧が印加されている複数の領域で反射、拡散され、第１基板ＳＵＢ１の主面および第２基板ＳＵＢ２の主面から出射して画像を形成する。３色に発光するＬＥＤ２４を用いた場合、組合わせにより７色の発色が可能であり、液晶表示パネル３０Ａ、３０Ｂ、３０Ｃの３つの表示パターンを組合わせることにより、表示装置１０は最大２１パターンの画像を表示することが可能となる。もちろん、当該パターン数等は例示であって、液晶表示パネルの積層数を３枚から増減する、あるいは、３色以外の複数色で発光するＬＥＤや、これらＬＥＤの配置数や発光パターンを変更することにより、表示装置の表示パターンは上記２１パターン以外のパターンでも実行可能である。 In the display device 10 having the above configuration, the light emitted from the LED 24 is diffused through the diffusion sheet DS, and then one side surface of the display panel 30, that is, one side surface SS1 and three sheets of the first substrate SUB1. It is incident on one side surface SS3 of the second substrate SUB2. The incident light is reflected and diffused in a plurality of regions to which the voltage of the liquid crystal layer LQ is applied, and is emitted from the main surface of the first substrate SUB1 and the main surface of the second substrate SUB2 to form an image. When the LED 24 that emits light in three colors is used, seven colors can be developed by the combination, and by combining the three display patterns of the liquid crystal display panels 30A, 30B, and 30C, the display device 10 has a maximum of 21 patterns. It becomes possible to display an image. Of course, the number of patterns and the like is an example, and the number of stacked liquid crystal display panels is increased or decreased from three, or LEDs that emit light in a plurality of colors other than the three colors, the number of arrangements of these LEDs, and the emission pattern are changed. As a result, the display pattern of the display device can be executed by a pattern other than the above 21 patterns.

液晶表示パネル３０Ａ、３０Ｂ、３０Ｃの一側面と発光素子との間に拡散シートＤＳが設けられているため、発光素子から出射した光を拡散シートＤＳで拡散して液晶表示パネル３０Ａ、３０Ｂ、３０Ｃの一側面に入射する。これにより、発光素子と第１基板ＳＵＢ１の一側面ＳＳ１との距離と、発光素子と第２基板ＳＵＢ２の一側面ＳＳ３との距離とが相違している場合でも、輝度ムラの発生を防止することができる。同時に、拡散した光を３枚の液晶表示パネル３０Ａ、３０Ｂ、３０Ｃに入射することができるため、複数の発光素子あるいは３色の発光素子を用いた場合でも表示パネルの色割れの発生は著しく抑制される。 According to the display device 10 according to the present embodiment configured as described above, a display panel 30 in which a plurality of liquid crystal display panels 30A, 30B, and 30C are stacked is provided, and a light emitting element commonly used for these panels is provided. ing. According to the display device 10, since the display panel as a whole becomes thicker, a high-brightness LED having a relatively large size, a high-output three-color LED, or the like can be adopted.
Since the diffusion sheet DS is provided between one side surface of the liquid crystal display panels 30A, 30B, 30C and the light emitting element, the light emitted from the light emitting element is diffused by the diffusion sheet DS, and the liquid crystal display panels 30A, 30B, 30C Incident on one side. As a result, even if the distance between the light emitting element and the one side surface SS1 of the first substrate SUB1 and the distance between the light emitting element and the one side surface SS3 of the second substrate SUB2 are different, the occurrence of luminance unevenness can be prevented. Can be done. At the same time, since the diffused light can be incident on the three liquid crystal display panels 30A, 30B, and 30C, the occurrence of color cracking of the display panel is remarkably suppressed even when a plurality of light emitting elements or three color light emitting elements are used. Will be done.

以上のことから、本実施形態によれば、輝度ムラ、色割れの発生を防止し表示品位の向上した表示装置が得られる。 According to the present embodiment, the main body 14 of the support 12 is formed of a metal material having high thermal conductivity, and the first printed circuit board 22A on which the LED 24 is mounted is provided in close contact with the main body 14. The heat generated from the LED 24, which is a heat source, is transmitted to the main body 14 via the first printed circuit board 22A, and is dissipated from the main body 14 to the outside air. As a result, the temperature of the LED 24 does not rise excessively, malfunctions and deformations of the LED 24 and the first printed circuit board 22A due to heat can be prevented, and the reliability of the display device can be improved.
From the above, according to the present embodiment, it is possible to obtain a display device having improved display quality by preventing the occurrence of luminance unevenness and color cracking.
