Description

  The present invention relates to a display device with a touch panel. More specifically, the present invention relates to a display device with a touch panel that prevents sticking between the touch panel and the display device without degrading the display quality of the display device.

  Conventionally, a touch panel, which is a device that operates a computer by touching the screen with a finger or a dedicated pen (touch pen), is a PDA (Personal Digital Assistance), a bank ATM (Adobe Type Manager), from a station ticket machine to a personal computer, Widely used in television and portable game machines.

  The touch panel detects the touched position by touching the surface with a finger or a touch pen, and outputs a signal corresponding to the touched position. And it is an input device which detects the touched position by the controller connected to the touch panel. Therefore, it is possible to input only by touching the display screen with a finger or pressing it with a touch pen.

  In addition, for sensing the touch of the screen on the touch panel, there are used three types of capacitance type (electrostatic type), resistive film type (pressure sensitive type), and infrared sensing type (optical type). Specifically, the pressure-sensitive type senses a change in pressure, the electrostatic type senses an electric signal due to static electricity, and the optical type senses a touch on the screen mainly by detecting the blocking of infrared rays. As described above, there are various types of touch detection on the touch panel, and any type of touch panel is basically mounted on the display device.

  Generally, a pressure-sensitive touch panel has a glass plate with a transparent electrode such as ITO (Indium Tin Oxide) on the display side, and a flexible transparent resin with a thin film transparent electrode on the touch panel side. Using a film (for example, polyethylene terephthalate film), the electrode surfaces are arranged to face each other with an insulating spacer interposed therebetween. Here, the back surface of the touch panel, which is generally the back side of the display device, is made of glass or plastic. For this reason, the back surface of the touch panel is mostly a smooth surface due to problems with materials such as glass and plastic.

  Usually, the touch panel is used in combination with a display device such as a liquid crystal display or a CRT (Cathode Ray Tube) display. In a liquid crystal module of a liquid crystal display equipped with a touch panel, a polarizing plate is often disposed on the uppermost layer. Further, in the CRT of the CRT display, the surface is often glass, and both the polarizing plate and the CRT are often smooth surfaces.

  Generally, in a display device with a touch panel, when the touch panel directly contacts the surface of the liquid crystal display, the thickness of the liquid crystal layer changes because stress is applied to the liquid crystal display. The display quality changes with the change in the thickness of the liquid crystal layer. In other words, since a phenomenon in which the color changes occurs, the touch panel is mounted with a space on the display device in order to avoid the change in color.

  Recently, with the expansion of the use of touch panels, requirements in terms of quality and performance have become strict, and further improvements in transparency and visibility have been demanded.

For example, Patent Document 1 discloses a touch panel that suppresses Newton's rings that occur during an input operation by making the opposing electrode surfaces in the touch panel rough. In the touch panel of Patent Document 1, since the opposing electrode surfaces are rough, even if the electrode surfaces come into contact with each other during the input operation, they do not adhere to each other. Therefore, the Newton ring which arises when smooth surfaces partly adhere can be suppressed, and the visibility of a touch panel is improved.

However, in the conventional display device with a touch panel, when the touch panel is pressed with a finger or a touch pen, stress is applied to the surface of the touch panel, so that the touch panel is distorted. Sticks due to surface tension). When the back surface of the touch panel and the uppermost surface of the display device are attached, there arises a problem that characters or pictures appear double or distorted due to problems such as refractive index. In addition, there is a problem that the touch panel is recessed in appearance and the appearance is deteriorated.

  As a method for solving the above problem, for example, a method of processing the surface of the polarizing plate into a rough surface is conceivable. However, in the method of processing the surface of the polarizing plate into a rough surface, light is irregularly reflected on the surface of the polarizing plate. Further, there arises a problem that the display quality of the display device is deteriorated such that a display image such as a character or a picture is blurred, or the contrast is lowered to make it difficult to see.

  The present invention has been made in view of the above-described conventional problems, and an object thereof is to provide a display device with a touch panel that realizes high visibility and display quality by suppressing sticking between the touch panel and the display device. There is to do.

  In order to solve the above-described problem, a display device with a touch panel according to the present invention includes a display device and a touch panel disposed with a space between the display device and a support portion. The space is provided with a spacer for maintaining a distance between the display device and the touch panel when the touch panel is operated.

  According to the above invention, when the touch panel is distorted in the direction of the display device during operation of the touch panel, the surface of the distorted portion of the touch panel is prevented from contacting the surface on the uppermost layer of the display device by the spacer. However, when there is no spacer, a strong surface free energy is generated because the distorted surface of the touch panel comes into surface contact with the surface of the uppermost layer of the display device. Then, the contact surfaces stick to each other due to the strong surface free energy. However, when there is a spacer, even if the distorted surface of the touch panel and the surface of the uppermost layer of the display device are in contact with each other, the contact is not a surface contact but a point contact. Therefore, no strong surface free energy is generated between the distorted surface of the touch panel or the surface of the uppermost layer of the display device and the spacer. And since the back surface of a touch panel and the surface of the uppermost layer of a display apparatus do not stick, the surface of a touch panel is not distorted and appearance does not deteriorate. In addition, since the surface of the touch panel is not distorted, light is not refracted due to the distortion of the surface of the touch panel. Therefore, characters and pictures displayed on the display device are visually recognized through the touch panel according to the original refractive index of light. Therefore, the visibility of displayed characters and pictures does not deteriorate. As a result, high visibility and display quality of the display device with a touch panel can be realized.

  In the display device with a touch panel according to the present invention, it is preferable that the spacer is provided in a non-contact manner on either the touch panel or the display device.

  Thereby, even when the spacer which a Newton ring is formed by contact with a touch panel or a display apparatus is arrange | positioned between a touch panel and a display apparatus, a spacer does not contact a touch panel or a display apparatus at the time of non-operation. That is, when the touch panel is not operated, a Newton ring is not formed which is generated when the spacer contacts the touch panel or the display device. Even when the touch panel is operated, the contact between the touch panel or the display device and the spacer remains a point contact, so that strong surface free energy does not occur. Therefore, the touch panel or the display device and the spacer are immediately separated. That is, the Newton ring generated by the contact between the touch panel or the display device and the spacer disappears in an instant. Therefore, compared to the case where the spacer is in contact with both the touch panel and the display device, it is less susceptible to Newton rings. As a result, the visibility of the display device with a touch panel is maintained high.

  In the display device with a touch panel according to the present invention, the spacer may be interposed between the back surface of the touch panel or the uppermost surface of the display device when the touch panel is distorted in the display device direction when the touch panel is operated. The contact area is preferably formed so as not to cause sticking.

  As a result, the surface of the distorted portion of the touch panel has a sufficient contact area so that the spacer does not stick to the back surface of the touch panel or the uppermost surface of the display device. Can be prevented from sticking to the spacer. And since the back surface of a touch panel and the surface of the uppermost layer of a display apparatus do not stick, the surface of a touch panel is not distorted and appearance does not deteriorate. In addition, since the surface of the touch panel is not distorted, light is not refracted due to the distortion of the surface of the touch panel. Therefore, characters and pictures displayed on the display device are visually recognized through the touch panel according to the original refractive index of light. Therefore, the visibility of displayed characters and pictures does not deteriorate. As a result, higher visibility and display quality of the display device with a touch panel can be realized.

  In the display device with a touch panel according to the present invention, the spacer preferably includes a plurality of spacers.

  Thereby, since there are a plurality of spacers, the spacers can be arranged over a wide space between the touch panel and the display device. Therefore, regardless of where the operation is performed on the touch panel, the spacer is widely arranged, so that the distorted surface of the touch panel can come into contact with the spacer regardless of where the touch panel is distorted in the display device direction. The possibility increases. That is, since the spacer and the distorted surface of the touch panel can come into contact with any part of the lower part of the touch panel, sticking between the back surface of the touch panel and the uppermost surface of the display device can be suppressed over a wide area below the touch panel. Therefore, the surface of the touch panel is not distorted over the wide area of the touch panel, and the appearance does not deteriorate. In addition, since the surface of the touch panel is not distorted, light is not refracted due to the distortion of the surface of the touch panel. Therefore, characters and pictures displayed on the display device are visually recognized through the touch panel according to the original refractive index of light. Therefore, it is possible to prevent a reduction in the visibility of displayed characters and pictures over a wide range of the touch panel. As a result, high visibility and display quality can be realized over a wide area of the touch panel.

  In the display device with a touch panel of the present invention, it is preferable that the spacers are arranged uniformly.

  As a result, characters and pictures displayed by the display device are uniformly affected by light refraction by the photo spacer on the touch panel. For this reason, uniformly shifted characters and pictures are visually recognized on the touch panel. At this time, since characters and pictures are uniformly shifted, the display is not uneven and the visibility is not changed.

  Further, according to the present invention, since the spacer is uniformly arranged regardless of the part on the touch panel, the distorted surface is the spacer even if the touch panel is distorted in the display device direction at any part of the touch panel. Can be contacted with a uniform probability. That is, the probability that the spacer does not come into contact with the spacer can be kept low. In this way, since the spacer and the distorted surface of the touch panel can be uniformly contacted at any part of the lower part of the touch panel, the back surface of the touch panel and the uppermost surface of the display device should be evenly adhered to the entire area of the lower part of the touch panel. Can be suppressed. Therefore, the surface of the touch panel is not uniformly distorted over the entire area of the touch panel, and the appearance does not deteriorate. In addition, since the surface of the touch panel is not distorted, light is not refracted due to the distortion of the surface of the touch panel. Therefore, characters and pictures displayed on the display device are visually recognized through the touch panel according to the original refractive index of light. Accordingly, it is possible to suppress a reduction in the visibility of displayed characters and pictures uniformly over the entire area of the touch panel. As a result, it is possible to prevent the display quality and visibility from being lowered uniformly across the entire touch panel.

  In the display device with a touch panel according to the present invention, when the touch panel is distorted in the direction of the display device, the back surface of the touch panel and the uppermost surface of the display device are in surface contact. It is preferable to arrange uniformly so that it may not.

  Thereby, no matter which part of the touch panel is distorted in the display device direction during operation, the back surface of the touch panel and the uppermost surface of the display device are not in surface contact. Therefore, strong surface free energy does not occur between the back surface of the touch panel and the uppermost surface of the display device. Therefore, the back surface of the touch panel and the uppermost surface of the display device do not stick. That is, the surface of the touch panel is not distorted. In addition, since the surface of the touch panel is not distorted, light is not refracted due to the distortion of the surface of the touch panel. Therefore, characters and pictures displayed on the display device are visually recognized through the touch panel according to the original refractive index of light. Therefore, the visibility of displayed characters and pictures does not deteriorate. As a result, high visibility and display quality of the display device with a touch panel can be realized.

  In the display device with a touch panel of the present invention, the spacer is preferably made of glass, silica, or plastic beads.

  As a result, glass, silica, or plastic beads are durable enough to withstand the vertical stress applied during operation of the touch panel, ensuring stable contact between the back surface of the touch panel and the uppermost surface of the display device. Can continue to prevent. Therefore, it is possible to stably prevent distortion of the surface of the touch panel. Further, in order to prevent the surface of the touch panel from being distorted, light is not refracted by the surface of the touch panel. Therefore, characters and pictures displayed on the display device are visually recognized through the touch panel according to the original refractive index of light. Therefore, it is possible to continue to prevent deterioration of the visibility of characters and pictures that are stably displayed. As a result, it is possible to stably achieve high visibility and display quality of the display device with a touch panel.

  Furthermore, since glass, silica, or plastic beads are inexpensive, the display device with a touch panel of the present invention can be manufactured with less cost. Therefore, high visibility and display quality of the display device with a touch panel can be realized with less cost.

  In the display device with a touch panel of the present invention, the spacer is preferably a photo spacer.

  Thereby, the arrangement of the photo spacers is performed according to the pattern of the photoresist. For this reason, it is possible to freely arrange the photo spacers by using an arbitrarily set photoresist pattern. Therefore, the photo spacers can be easily arranged at the above-mentioned intervals only by setting the photoresist pattern at a uniform interval so that the back surface of the touch panel and the uppermost surface of the display device do not come into surface contact during operation. . As described above, high display quality and visibility of the touch panel can be realized by arranging the spacers at a uniform interval so that the back surface of the touch panel and the uppermost surface of the display device do not come into surface contact during operation. As a result, high display quality and visibility can be easily realized by using a photo spacer.

  In the display device with a touch panel of the present invention, it is preferable that the photo spacer has a plurality of columns or cylinders.

  Thereby, the surface contact of a touch panel and a display apparatus can be prevented also by the photo spacer which consists of a some column shape or cylinder shape. Therefore, it is possible to prevent distortion of the surface of the touch panel and a decrease in the visibility of characters and pictures displayed by the display device. As a result, high visibility and display quality of the display device with a touch panel can be realized.

  In the display device with a touch panel according to the present invention, the photo spacer is preferably formed in a stripe shape or a lattice shape.

  Thereby, the surface contact of a touch panel and a display apparatus can be prevented also with the photo-spacer formed in stripe form or a grid | lattice form. Therefore, it is possible to prevent distortion of the surface of the touch panel and a decrease in the visibility of characters and pictures displayed by the display device. As a result, high visibility and display quality of the display device with a touch panel can be realized.

  In the display device with a touch panel of the present invention, it is preferable that a plurality of glass, silica, or plastic beads are arranged in the striped or grid-like photo spacer.

  As a result, even if the glass, silica, or plastic beads are not fixed to the touch panel or display device by bonding or the like, the glass, silica, or plastic beads are moved by placing them in the striped or grid-like photo spacers. Can be limited. Therefore, non-fixed glass, silica or plastic beads can be arranged more uniformly. And it becomes possible to suppress distortion of the surface of a touch panel uniformly in the whole region of a touch panel by arranging glass, silica, or plastic beads more uniformly. In addition, it is possible to suppress deterioration in the visibility of displayed characters and pictures uniformly over the entire area of the touch panel. As a result, it is possible to prevent the display quality and visibility from being lowered uniformly across the entire touch panel.

  As described above, the display device with a touch panel according to the present invention includes the display device and the touch panel arranged with a space between the display device and the support unit, and maintains the distance between the display device and the touch panel. Spacers are provided.

  Therefore, when the touch panel is distorted in the direction of the display device when the touch panel is operated, even if the distorted surface of the touch panel and the surface on the uppermost layer of the display device are in contact with each other, the contact is not a point contact but a point contact. Therefore, the back surface of the touch panel does not stick to the uppermost surface of the display device.

  Therefore, there is an effect that it is possible to provide a display device with a touch panel that realizes high visibility and display quality by suppressing sticking between the touch panel and the display device.
