Description

  The present invention relates to a bezel, a display element, and a display device in which measures against EMI (Electromagnetic Interference) are taken.

  Conventionally, bezels are widely used for the purpose of protecting and fixing display panels.

  FIGS. 12 and 13 both show the prior art. FIG. 12 is a perspective view of the bezel 110 and FIG. 13 is a plan view of the liquid crystal display element 102.

  As shown in FIG. 12, the bezel 110 is a so-called metal chassis, and has a frame 110c formed in a square shape by four metal sides as its main part.

  Further, as shown in FIG. 13, the bezel 110 surrounds the periphery of the display surface of the display panel such as the liquid crystal panel 106 and corresponds to the display portion of the display surface (the portion other than the periphery of the display surface). Is formed into a frame shape with respect to the display panel.

  The main reason why a metal material is used as the material of the bezel is that it is easy to ensure rigidity. That is, it is possible to reduce the thickness and the width of the frame when securing the same degree of rigidity as a bezel using a resin material. Specific examples of the metal material include aluminum, iron, and stainless steel.

  Another reason that metal is used as the material of the bezel is to shield the drive circuit element of the display panel electrostatically and electromagnetically.

  First, electrostatic shielding (electrostatic shielding) will be described. The electrostatic shielding of the drive circuit elements includes (1) preventing static electricity generated from the drive circuit elements to prevent element breakdown due to sparks and malfunction due to capacitance, and (2) And preventing the influence of an external electric field. In both (1) and (2), the bezel is formed of metal and, for example, the bezel is connected to a metal member constituting a frame ground such as a case or a chassis included in the casing of the display device. To do.

  Next, electromagnetic shielding (electromagnetic shielding) will be described. This electromagnetic shielding is required mainly from the viewpoint of noise countermeasures related to display elements, specifically EMC (Electromagnetic Compatibility) countermeasures. The EMC countermeasure includes an EMS (Electromagnetic Susceptibility) countermeasure and an EMI (Electromagnetic Interference) countermeasure. The former EMS countermeasure is a countermeasure for reducing the influence of external noise, and the latter EMI countermeasure is a countermeasure for reducing the influence of external noise. If the bezel is made of metal, the influence of noise on the latter can be suppressed to some extent by the electromagnetic shielding effect of the bezel (EMI countermeasures).

  As described above, by using a metal as the material of the bezel, not only ensuring rigidity but also electrostatic shielding and electromagnetic shielding of the drive circuit element can be achieved.

  However, even if a bezel made of the above-described metal is used, EMI countermeasures are not sufficient, and the influence of external noise remains.

Therefore, various configurations have been proposed as EMI countermeasures other than the configuration using a metal bezel. For example, Patent Document 1 proposes a configuration in which an electromagnetic wave shielding film is disposed on the front surface of the display. Patent Document 2 proposes a configuration in which a protective panel that functions as an electromagnetic wave absorption filter is disposed on the front surface of the display.
JP 11-233992 A (published August 27, 1999) Japanese Patent Laid-Open No. 11-352897 (published on December 24, 1999)

  However, although the configurations described in Patent Document 1 and Patent Document 2 are effective to some extent as an EMI countermeasure, new parts are required, resulting in an increase in product cost, and between the display and the viewer. In addition, since a film, a filter, and the like are disposed, there are problems such as a reduction in the sharpness of the image.

Here, EMI countermeasures and noise generated inside the display element will be described in more detail.
(Measures against unnecessary radiation and noise terminal voltage)
First, noise countermeasures included in the EMI countermeasures include unwanted radiation countermeasures and noise terminal voltage countermeasures. The measure against unwanted radiation is a measure against radio waves directly radiated from the device, and the measure against noise terminal voltage is a measure against voltage noise conducted to an AC (Alternate Current) power line.

As the EMI countermeasure in the display device, the former countermeasure against unnecessary radiation is mainly used. This is because the display device includes various circuits such as a drive circuit, and noise generated therefrom is large.
(Normal mode noise and common mode noise)
Next, the noise that is the target of the unwanted radiation countermeasure will be described in more detail. The main noises that are subject to unwanted radiation countermeasures are normal mode noise and common mode noise. The normal mode noise is mainly noise due to radiation from the board, while the common mode noise is mainly noise due to radiation from the cable.

  FIG. 10 is a conceptual diagram showing a radiation model for normal mode noise, and FIG. 11 is a conceptual diagram showing a radiation model for common mode noise. 10 and 11, a thick line arrow indicates a noise current, and a thin line arrow indicates a radiated noise radio wave. Also, the double-headed arrow in FIG. 11 represents the antenna length in the dipole antenna model.

  As shown in FIG. 10, normal mode noise is caused by noise current in a loop circuit composed of a combination of a circuit connected from the transmission side to the load side and a circuit returning from the load side (thick line single arrow in FIG. 10). Is generated as a noise wave (a thin line arrow in FIG. 10) when this circuit functions as a loop antenna. Here, noise (noise radio wave) radiated from the loop antenna is proportional to the area of the loop surface surrounded by the loop circuit and the square of the noise current.

  On the other hand, as shown in FIG. 11, the common mode noise is a noise generated when each line of the cable has a potential from the ground which is a reference potential plane, and a noise current (a thick line single arrow in FIG. 11) flows there. When this cable functions as a dipole antenna, it is radiated as noise radio waves (thin arrows in FIG. 11). Here, the noise radiated from the dipole antenna (noise radio wave) is proportional to the antenna length and the square of the noise current.

  Further, the present inventor has found that the bezel used for protecting the display panel in the display element functions as a loop antenna that radiates the normal mode noise, and may increase unnecessary radiation of the normal mode noise. I found it.

  Specifically, for example, when an input from the user interface is input to the drive circuit element via the control board and particularly high-frequency normal mode noise is generated, this noise propagates to the metal bezel to generate a small current in the bezel. . Then, it was found that the minute current circulates around the bezel, so that the bezel functions as a loop antenna and may contribute to the emission of noise radio waves.

  As described above, the bezel used not only for securing rigidity but also as an EMI countermeasure has a noise radio wave radiation action that is an action contrary to the EMI countermeasure, thereby reliably suppressing noise radio wave radiation. It is thought that EMI countermeasures were insufficient. Therefore, the present invention has been made in view of the above-mentioned problems and considerations on noise of display elements, and the object thereof is to suppress an increase in product cost due to the need for new parts, and image It is an object of the present invention to provide a bezel, a display element, and a display device that can further reduce unnecessary radiation, in particular, unnecessary radiation of normal mode noise, while suppressing a decrease in sharpness of the image.

  In order to solve the above problems, a bezel according to the present invention is a bezel used for a display panel, and is characterized by being made of a conductor that does not constitute a loop.

  According to the above configuration, the bezel does not function as a loop antenna because the bezel does not form a conductor loop. Therefore, the bezel does not serve as an antenna that radiates noise generated from the inside of the display element, particularly normal mode noise. Therefore, noise generated inside the display element is not promoted to be radiated outside the display element. As a result, unnecessary radiation can be more reliably suppressed.

  In addition, the above-described configuration is such that a conductor loop is not configured for the bezel itself that has been used in conventional display elements. That is, it does not add new parts that have not been conventionally used. Therefore, an increase in product cost due to the need for new parts can be suppressed.

  Furthermore, the above-described configuration is a configuration having a characteristic of the bezel, and is not a configuration in which a member is arranged on the display portion of the display surface. Therefore, it is possible to suppress a decrease in the sharpness of the image.

  As described above, the above configuration suppresses unnecessary radiation, particularly normal mode noise, while suppressing an increase in product cost due to the need for new parts and suppressing a decrease in image sharpness. A bezel that can be further reduced can be provided.

  Further, the bezel according to the present invention is a bezel used for a display panel, wherein at least one portion of the loop is made of a conductor having a divided shape, and one end of the conductor at the divided portion. It is characterized by being configured in a loop shape by a portion made of a non-conductive material connecting the other end.

  According to the said structure, the strength reduction of the bezel which may arise by forming a parting part in a bezel can be suppressed. This will be described below.

  The bezel is used for the purpose of protecting the display panel as described above. Therefore, for example, when a part of the B-shaped bezel that is one form of the loop is divided into the sides located on the vertical side, or when the display panel falls, the display caused by insufficient strength of the bezel Damage to the panel may occur. In this respect, according to the above-described configuration, the end portions of the conductors generated by the division are connected by the non-conductor such as an insulator, so that the bezel has a complete square shape with no division part as a whole. Have. Therefore, since the strength reduction of the bezel is suppressed, damage to the display panel can be suppressed.

  Moreover, according to the said structure, since the edge part of the conductor which opposes is connected by the nonconductor, the frame does not comprise the loop of the conductor. Therefore, the achievement of the object of the present invention to further suppress the unnecessary radiation is not hindered.

  In addition, according to the said structure, the new components called a nonconductor are needed. However, since this non-conductor is disposed at the divided portion of the bezel, for example, unlike a component disposed on the entire display surface of the display element, an increase in manufacturing cost is negligible. Therefore, an increase in product cost, which is a problem of the present invention, can be suppressed even with the above configuration.

  Further, the display element according to the present invention is characterized in that the display panel is provided with the bezel. In addition, the display device according to the present invention includes the display element.

  Here, the display element is a display component unit that includes at least a display panel and a bezel, and generally includes a light source device, a drive circuit element, and the like, and is a component that controls display in various display devices. It is a component part for display used as.

  The display device refers to a device provided with the display element. Specifically, for example, when a liquid crystal panel is used as the display panel, the display device is a liquid crystal television or a liquid crystal monitor. When a plasma panel is used as the display panel, the display device is a plasma television or a plasma monitor. Sure.

  According to the above configuration, since the display element or the display device includes the bezel in which the frame does not form a conductor loop, an increase in product cost due to the need for new parts is suppressed. In addition, it is possible to provide a display element and a display device that can further reduce unnecessary radiation, in particular, unnecessary radiation of normal mode noise, while suppressing a decrease in the definition of an image.

  As described above, the bezel, the display element, and the display device according to the present invention are configured by a conductor that does not form a loop, and therefore, an increase in product cost due to the need for new parts is suppressed. In addition, there is an effect that it is possible to provide a bezel, a display element, and a display device that can further reduce unnecessary radiation, particularly unnecessary radiation of normal mode noise, while suppressing a decrease in the sharpness of an image.

[Embodiment 3]
The following will describe another embodiment of the present invention with reference to FIGS. Configurations other than those described in the present embodiment are the same as those in the first embodiment. For convenience of explanation, members having the same functions as those shown in the drawings of the first embodiment are given the same reference numerals, and explanation thereof is omitted.

  In the liquid crystal display element of the present embodiment, unlike the liquid crystal display elements of the other embodiments, the bezel 10 is formed by assembling a plurality of members, and the joint portion of the members is divided with the dividing portion (A).
