Description

The present invention applies light transmission processing along the shape of the characters, figures, symbols, etc. to the display unit and key operation unit for displaying characters, figures, symbols, etc. that the user wants to visually recognize. By applying a light blocking process or a light reducing process to a part other than the processed part, and emitting light from the light emitting part only through the part subjected to the light transmission process, the character, For example, a mobile phone, a PHS phone (PHS: Personal Handyphone System), a PDA device (PDA: Personal Digital Assistant), a notebook personal computer device, or a desktop personal computer device having a display function for visually recognizing figures, symbols, etc. Display device suitable for installation in various electronic devices such as audio devices, video camera devices, digital camera devices, portable and stationary game machines, etc. The present invention relates to a forming method, a key device, a key device forming method, an electronic apparatus, and a portable terminal device.
In particular, a mesh member having a predetermined mesh shape is provided between the light emitting unit and the display unit, or between the light emitting unit and the key operation unit, in the same color as the display unit or the key operation unit. Thus, when the light emitting unit is turned on, the light, emitted from the light emitting unit through the light-transmitted portion is made visible to the user, and the light emitting unit is turned off. In some cases, by using a mesh-like member of the same color as the display unit or key operation unit, the portion subjected to light transmission processing such as characters, figures, symbols, etc. is assimilated (same color) with the color of the display unit or key operation unit. The present invention relates to a display device, a display device formation method, a key device, a key device formation method, an electronic apparatus, and a mobile terminal device that are difficult for the user to see.

  Japanese Laid-Open Patent Publication No. 2008-130277 (Patent Document 1) discloses a mobile phone having a key structure capable of forming a graphic color visually recognized by a user as black. In the case of this cellular phone, a key structure having an LED (LED: Light Emitting Diode) on one side of the translucent key top portion and a switch that is turned on / off according to the operation of the key top portion is provided. And a black graphic color layer in which the other side of the key top part (= the side opposite to the side where the LED and the switch are provided) is transparent and mixed with a blue color material, and a predetermined graphic A key structure in which a black light-shielding layer that does not contain a blue color material and a top layer in which holes of predetermined shapes are formed are sequentially stacked.

  In the case of such a key structure, when the LED is turned on, the light emitted from the LED is emitted outside the housing through holes of predetermined shapes formed in the light shielding layer and the top layer, respectively. The user will visually recognize the predetermined figure through the emitted light. On the other hand, when black and blue are mixed, it is visually recognized as almost black by human eyes. For this reason, the shading layer is formed when the LED is turned off by forming the figure color layer that determines the color of the figure with a material that is translucent and mixed with a black color material and a blue color material. And the figure color which a user visually recognizes as the black of the hole of the predetermined figure each formed in the said top layer can be formed.

  On the other hand, when the LED is turned on, predetermined characters, figures, symbols, etc. formed on the case, buttons, etc. are illuminated. When the LED is turned off, predetermined characters, figures, symbols formed on the case, buttons, etc. There is known a mobile phone having a key structure that makes it difficult to visually recognize the same color as that of the casing and buttons. To put it simply, when the LED is turned on, a predetermined character, figure, symbol, etc. is displayed on the casing or button. When the LED is turned off, the predetermined character, figure, symbol, etc. on the casing or button is displayed. There is known a mobile phone having a key structure in which the disappears.

  In the case of this cellular phone, as shown in FIG. 9 (a), the whole is formed of a transparent member, and has a casing 100 in which the entire back surface is subjected to black print processing. Of the black print processing unit 101 that has been subjected to the black print processing, a portion that displays an operation index is a transmission processing unit 101 that transmits light according to the shape of the operation index. An LED 104 and a light diffusing member 105 are provided between the housing 100 and the substrate 103. When the LED 104 is turned on, as shown in FIG. Is diffused by the light diffusing member 105 and emitted through the transmission processing unit 101. Since the shape of the transmission processing unit 101 is the shape of the operation index, the user visually recognizes the operation index by the light emitted through the transmission processing unit 101.

  On the other hand, when the LED 104 is turned off, when the user tries to visually recognize the operation index, the operation index is visually recognized based on the reflected light of the light that has entered the housing 100 via the transmission processing unit 101. It will be. The amount of light entering the housing 100 via the transmission processing unit 101 is small. For this reason, as shown in FIG. 9B, the color of the operation index is substantially assimilated to the color (black) of the casing 100 that has been subjected to the black printing process, and the operation index disappears from the casing 100. (= It becomes difficult for the user to visually recognize the operation index).

  However, in the case of this mobile phone, since there is no visually hindering part between the transmission processing unit 101 and the light diffusion member 105, the light diffusion member is interposed via the transmission processing unit 101 when the LED 104 is turned off. The 105 colors can be visually recognized. This means that, even when the LED 104 is turned off, the operation index is visually recognized by the user, although slightly. Therefore, in the case of this mobile phone, there is a problem that the operation index cannot be completely turned off from the housing 100 when the LED 104 is turned off.

  For this reason, as shown in FIG. 10, there is also known a mobile phone that has been subjected to dot printing processing (dot print processing) for printing countless dots (dots) on the transmission processing unit 101. In the case of this cellular phone, when the LED 104 is lit, light from the LED 104 is emitted through the gaps of the dots of the transmission processing unit 101 as shown in FIG. Thereby, the user visually recognizes the operation index on the housing 100.

  On the other hand, when the LED 104 is turned off, each dot of the transmission processing unit 101 becomes a visual obstacle in visually recognizing the light diffusion member 105 as shown in FIG. In order to reduce the amount of light incident on the housing 100, it is difficult to visually recognize the light diffusion member 105 through the transmission processing unit 101. Innumerable dots printed on the transmission processing unit 101 make the color of the colorless and transparent transmission processing unit 101 visible as a gray color. For this reason, when the LED 104 is turned off, the entire housing 100 is black, so that the operation indicator visually recognized by the gray color becomes inconspicuous, and the operation indicator can be almost erased from the housing 100.

JP 2008-130277 (Page 5, FIG. 2, FIG. 3)

  However, in the case of the mobile phone disclosed in Patent Document 1, a so-called black film in which a blue color material is mixed is pasted into holes of predetermined shapes formed in the light shielding layer and the top layer, respectively. The graphic color layer is provided. For this reason, the entire hole of the predetermined figure is covered with the graphic color layer without any gap, and when the LED is turned on, the light transmitted through the hole of the predetermined figure is blocked by the graphic color layer and transmitted. There is a problem that the predetermined figure is displayed darkly.

  If the LED is lit and driven with high brightness, the problem that the predetermined figure is displayed darkly is reduced to some extent. However, when the LED is lit and driven with high brightness, the power consumption of the battery increases. This is not preferable for a mobile phone.

  On the other hand, in the case of a mobile phone in which the dot printing process is performed on the transmission processing unit 101, the degree to which the operation index can be erased from the housing 100 when the LED is turned off (= the degree to which the operation index is difficult to visually recognize) is There is a problem that depends on accuracy.

  Specifically, when the dot printing process is performed on the transmission processing unit 101, for example, when clogging of the printing apparatus, ink dilution variation, ink curing, foreign matter adhesion during printing, and the like occur, as shown in FIG. Causes uneven printing. If this printing unevenness occurs, when the LED is lit, the operation index is visually recognized in a distorted shape, or the operation index is visually inconsistent, or the operation index is visually blurred. This is not preferable in terms of the design of the mobile phone.

  Such a problem becomes more prominent when the operation index is a character such as katakana or alphabet. That is, in this case, since the characters are crushed due to the printing unevenness, it is difficult for the user to visually recognize the characters even if the LED is turned on.

  In order to prevent the occurrence of such printing unevenness, it may be possible to develop a printing apparatus with high printing accuracy. However, in order to develop a printing apparatus with high printing accuracy, a large amount of development costs are required. There's a problem.

The present invention has been made in view of the above problems,
1. Without driving the light emitting part with high brightness, display objects such as operation indicators can be clearly displayed,
2. The display object can be clearly displayed without depending on the printing accuracy of the printing device.
3. When the light emitting unit is extinguished, the operation color can be erased from the case by making the case color and the color of the display object almost the same color (assimilation),
4). It is an object of the present invention to provide a display device, a display method, a key device, a key device forming method, an electronic device, and a portable terminal device that can be realized at low cost.

In order to solve the above-described problems, a display device according to the present invention provides
A light emitting unit;
A display unit including a light transmission unit that transmits light emitted by the light-emitting unit, and a light-blocking unit that blocks or reduces light transmitted through a portion other than the light transmission unit;
A mesh member having a color similar to that of the display portion and having a predetermined mesh shape, and provided between the light emitting portion and the light transmitting portion of the display portion.

  According to the present invention, when the light emitting unit is turned on, the light from the light emitting unit is emitted from the light transmitting unit through the gaps of the meshes of the mesh member. The display object corresponding to the shape of is visually recognized.

  On the other hand, when the light emitting unit is turned off, the mesh member having the same color as the display unit suppresses the incidence of light through the light transmitting unit, and the mesh member enters through the light transmitting unit. By reflecting the emitted light, light of the same color as the display unit is emitted through the light transmission unit. Accordingly, when the light emitting unit is turned off, the color of the light transmitting unit is made the same color (similarized) as the color of the display unit, so that it is very difficult to visually recognize the light transmitting unit on the display unit.

  The present invention can obtain the following effects.

  1. When the light emitting unit is turned on, the light emitted from the light emitting unit is emitted from the light transmitting unit through the meshes of the mesh member, so that the amount of light from the light emitting unit dimmed by the mesh member (Reduced light amount) can be extremely reduced, and the amount of light emitted from the light transmitting portion can be increased. For this reason, it is possible to display a display object such as a character or a figure that clearly corresponds to the shape of the light transmitting portion without driving the light emitting portion with high luminance. In addition, since it is not necessary to drive the light emitting portion with high luminance, power consumption can be reduced.

  2. By providing a mesh member between the light emitting portion and the light transmitting portion of the display portion, it is possible to eliminate the need for dot printing applied to the light transmitting portion. For this reason, since it is not necessary to perform this dot printing, the clear shape of the light transmission part can be maintained, and the display object can be clearly displayed. Moreover, since dot printing can be made unnecessary, the display object can be clearly displayed while using an existing printing apparatus without using a printing apparatus with high printing accuracy.

  3. When the light emitting unit is turned off, the mesh member having the same color as the display unit suppresses the incidence of light through the light transmission unit, and the mesh member reflects the light incident through the light transmission unit. In doing so, the light of the same color as the display unit is reflected, and the color of the light transmission unit is made the same color (assimilation) with the color of the display unit. Thereby, it is possible to make it very difficult to visually recognize the light transmission part on the display unit when the light emitting unit is turned off, and the presence of the light transmission part of the display unit can be almost completely erased visually. . This effect is very prominent and uses a conservative wording such as “substantially complete”, but it can visually eliminate the presence of the light transmitting part of the display part to the extent that it cannot be seen at all. is there.

  4). Since it can be realized with a simple configuration in which a mesh member is provided between the light emitting portion and the light transmission portion of the display portion, it can be realized with a very low cost and simple configuration. In addition, since the installation of the mesh-shaped member requires a very small installation area, it can be applied without changing the device size of the device to which the present invention is applied. Furthermore, since the mesh member can be easily installed, it can be installed without changing the configuration of the device to which the present invention is applied.

  The present invention is applied to a foldable mobile phone that allows opening and closing operations of an upper casing and a lower casing by connecting one end portions of the upper casing and the lower casing to each other via a hinge portion. be able to.

[Configuration of mobile phone]
First, Fig.1 (a) is the figure which looked at the upper housing | casing of the said mobile telephone made into the closed state from the front. As shown in FIG. 1A, the upper case 1 of the mobile phone is provided with a hinge portion 2 on one end 1a side, and is connected to the lower case via the hinge portion 2. . The outer surface portion 1b of the upper housing 1 exposed when the mobile phone is closed is formed so as to have a substantially planar shape as a whole, but the outer surface portion 1b includes In the vicinity of the other end portion 1c of the upper housing 1, projecting portions 3 to 5 projecting from the outer surface portion 1b are provided.

  FIG. 1B is a view in which a portion of the upper housing 1 where the protruding portions 3 to 5 are provided is cut along the short direction of the upper housing 1 and the cut surface is viewed from the front. (A-A line sectional view) is shown. As can be seen from FIG. 1B, each of the protrusions 3 to 5 has a substantially hemispherical shape. Of the protrusions 3 to 5, the protrusion 4 has the largest substantially hemispherical shape.

  As shown in FIG. 1A, the protruding portion 4 is provided in the vicinity of the other end 1 c of the upper housing 1 so as to be positioned at the approximate center of the upper housing 1. On the other hand, the protrusion 3 and the protrusion 5 have the same size and have a substantially hemispherical shape that is smaller than the protrusion 4. Further, the protruding portion 3 and the protruding portion 5 are provided on both sides of the protruding portion 4 so that approximately half of the whole overlaps with the protruding portion 4.

  As will be described later, in this example, the protrusions 3 to 5 have, for example, a playback instruction key, a stop instruction key, a next music playback specification key, a previous music playback specification key, a menu operation key, etc. It is a display unit for displaying the operation index.

  In addition, the entire upper casing 1 is reinforced with ABS resin (acrylonitrile, butadiene (Butadiene), styrene (Styrene) copolymer synthetic resin) or the like so as to have a transparent color or other light-transmitting color. It is formed using a plastic member. Further, as shown in FIG. 1B, the entire inner surface side of the upper housing 1 (for the entire surface facing the substrate accommodated in the upper housing 1). In addition, in order to set the upper casing 1 to a desired casing color, a printing process using an ink member such as black, white, orange, or beige is performed.

  By this printing process, the user can visually recognize the color of the ink by the printing process applied to the entire inner surface side through the transparent reinforced plastic member. It will be recognized as a color housing color. Further, although there are some differences depending on the color of the ink member used in the printing process, the upper casing 1 is totally shielded from light or dimmed by performing this printing process.

  The configuration of the upper casing 1 will be described in a little more detail. FIG. 2 is a view of the upper housing 1 as viewed from the inner surface side. As described above, as can be seen from FIG. 2, the inner surface side of the upper housing 1 is subjected to a light shielding process that does not transmit light or a light reduction process by printing using an ink member of a predetermined color as a whole. This is a light shielding / dimming portion.

  Further, on the inner surface side of the upper casing 1, a portion corresponding to the back side of each of the protrusions 3 to 5 includes a playback instruction key, a primary stop instruction key operated when the music player function of the mobile phone is activated, The operation indicator section that displays the next song playback specification key, the previous song playback specification key, the menu operation key (in this example, the cross key) for performing the menu operation for selecting the album or song to be played back, etc. Yes.

  That is, the entire upper casing 1 is formed of a transparent reinforced plastic member, and the entire inner surface side is subjected to a printing process (= light shielding / dimming process) using a predetermined color ink member. However, this shading / dimming process is performed except for the shape of each operation index such as a reproduction instruction key and a stop instruction key displayed on each protrusion 3 to 5 of the upper casing 1 (= (The print missing state is in conformity with the shape of the reproduction instruction key, the stop instruction key, and the like, and the printing process (light-shielding / light-reducing process) is applied to portions other than these operation indices). For this reason, the operation indicators such as the reproduction instruction key and the stop instruction key are a transparent light transmitting portion which is the color of the reinforced plastic member itself forming the upper housing 1.

  On the other hand, as will be described later, the upper half portion (= the portion above the display portion of the operation indicator), which is the portion indicated by the dotted-line rectangle in FIG. For example, it is a portion opposed to an auxiliary display unit such as an organic EL display unit (Organic ElectroLuminescence Display). As an example, in the case of this mobile phone, the auxiliary display unit displays the music title, album name, operation menu, etc. in only one color such as white. For this reason, on the inner surface side of the upper casing 1, the portion opposite to the auxiliary display section maintains the casing color of the upper casing 1 as a whole, and the operation displayed on the auxiliary display section. The printing process is performed so that a display item such as a menu can be visually recognized through the upper casing 1.

  That is, when a printing process that is a light-shielding process is performed on the lower half of the upper casing 1 that is the display portion of the operation index, the upper casing 1 includes the upper casing 1 in the upper casing. Printing that is dimmed so that the display color such as the operation menu displayed on the auxiliary display unit can be visually recognized through the upper casing 1 while maintaining the casing color of the entire body 1 Processing is performed.

  Even if the same printing process as the printing process performed on the lower half of the upper casing 1 that is the display part of the operation index is performed, the display items such as the operation menu displayed on the auxiliary display unit are not displayed. If visible through the upper housing 1, the same printing process is performed on the upper half portion and the lower half portion of the upper housing 1.

  In addition, when the same printing process as the printing process performed on the lower half of the upper casing 1 that is the display part of the operation index is performed, the display items such as the operation menu displayed on the auxiliary display unit are displayed. When it becomes difficult to visually recognize through the upper casing 1, the auxiliary display section is maintained while maintaining the casing color of the entire upper casing 1 with respect to the lower half of the upper casing 1. A display process such as a light reduction process is performed so that the display items such as the operation menu displayed on the screen can be viewed through the upper casing 1.

  Next, the upper housing 1 is formed by abutting an upper half and a lower half each having a substantially rectangular shape. FIG. 3 is a front view of the upper housing 1 with the upper half removed. As can be seen from FIG. 3, an auxiliary display section 11 such as the organic EL display section is provided in the upper casing 1 in the vicinity of one end 1 a of the upper casing 1. Further, in the upper casing 1, orange light is respectively provided at positions corresponding to the protrusions 3 to 5 that display the operation indicators (so that they are directly below the protrusions 3 to 5). Light emitting units OL1 to OL5 such as LEDs (LED: Light Emitting Diode) that emit light, and light emitting units WL1 to WL5 such as LEDs that emit white light are provided. In FIG. 3, each light emitting portion that emits orange light is illustrated in a square shape with hatching, and each light emitting portion that emits white light is illustrated in a white square shape.

It is a light emitting unit for displaying.

  In addition, the light emitting unit WL2 includes an upward operation key for designating an upward movement operation of the cursor displayed on the auxiliary display unit 11, an upward scrolling operation menu, and the like. The light emitting unit WL3 is configured to perform a downward movement operation of the cursor displayed on the auxiliary display unit 11, a downward scrolling operation menu, and the like. It is a light emitting unit for displaying a downward operation key for designating on the protruding portion 5 of the upper housing 1.

  In addition, the light emitting unit WL4 includes a left operation key for designating a leftward movement operation of the cursor displayed on the auxiliary display unit 11, a leftward scroll operation of the operation menu, and the like. The light emitting unit WL5 displays a movement operation of the cursor displayed on the auxiliary display unit 11 in the right direction, a scroll operation in the right direction of the operation menu, and the like. This is a light emitting unit for displaying a right operation key for designating on the protruding portion 5 of the upper housing 1.

  Further, a cross-shaped recess 12 is provided on the substrate housed in the upper housing 1. The orange light emitting section OL1 for displaying the reproduction instruction key and the primary stop instruction key, and the white light emitting section WL1 for displaying the determination key are positioned substantially at the center of the cross-shaped recess 12. Two are provided side by side. Further, the other light emitting portions WL2 to WL5 that emit white light are provided so as to be positioned on the upper, lower, left, and right sides in the cross-shaped concave portion 12, respectively. Accordingly, the light emitting portions OL1, WL1 to WL5 provided in the cross-shaped recess 12 are embedded at positions lower than the plane of the substrate.

  Further, a cylindrical light shielding member 13 having a cylindrical shape and subjected to a light shielding treatment is provided at a substantially center of the cross-shaped concave portion 12. The orange light emitting portion OL1 and the white light emitting portion WL1 provided at substantially the center of the cross-shaped concave portion 12 are provided so as to be surrounded by the light shielding cylindrical member 13 (= each light emitting portion OL1, And WL1 are provided in the light blocking cylinder member 13). For this reason, the orange and white light emitted by each of the light emitting sections OL1 and WL1 is emitted only in the direction of the open surface of the light shielding cylinder member 13 (upper vertical direction with respect to the paper surface of FIG. 3). ing.

  In addition, since the light emitting portions WL2 to WL5 provided in the upper, lower, left, and right sides of the cross-shaped concave portion 12 are provided at positions lower than the plane of the substrate, the cross-shaped concave portion 12 serves as a wall, The white light emitted by each of the light emitting portions WL2 to WL5 is emitted only in the open surface direction of the cross-shaped recess 12 (upper vertical direction with respect to the paper surface of FIG. 3).

  On the other hand, the orange light emitting portions OL2 to OL5, which are light emitting portions other than the light emitting portions OL1 and WL1 to WL5, are provided close to the top, bottom, left, and right outside the cross-shaped concave portion 12, respectively. As described above, the orange light emitting portions OL1 and the white light emitting portions WL1 to WL5 provided in the cross-shaped recess 12 are provided at positions lower than the plane of the substrate. “Light emitted from the light emitting sections OL1, WL1 to WL5 provided in the cross-shaped recess 12” and “Light emitted from the light emitting sections OL2 to OL5 provided outside the cross-shaped recess 12” , Each will not interfere.

  Next, FIG. 4 shows a cross-sectional view of a main part of the upper housing 1. As shown in FIG. 4, in the upper casing 1, each light emitting unit OL <b> 1 to OL <b> 5, WL <b> 1 to WL <b> 5 provided on the substrate 20 and printing by the printing process performed on the inner surface side of the upper casing 1 is performed.

As can be seen from FIGS. 5 (a) to 5 (c), the mesh member 24 has a size that covers at least each operation index that is a light-transmitting portion of the transparent color. It is formed by weaving a member such as a nylon fiber, a resin member, or a paper member in a mesh shape (lattice shape).

  The color of the mesh member 24 is similar to the color of the ink member (= casing color) of the print layer 21. For example, when a black ink member is used, the color of the mesh member 24 is “black”, and when an orange ink member is used, the color of the mesh member 24 is “orange”. When the white ink member is used, the color of the mesh member 24 is “white”.

  The mesh size of the mesh member 24 is such that when the light emitting portions (OL1 to OL5, WL1 to WL5) are turned on, the light from the light emitting portion is transmitted through the light transmitting portion having the shape of the operation index. When the light transmitting portion that can emit light and the light emitting portion is turned off and the light transmitting portion that is the operation index is viewed, the color of the light transmitting portion is the color of the upper casing 1 (in this case, the color of the ink). ) To be visually recognized in the same color.

Next, light emission control of the light emitting units OL1 to OL5 and the light emitting units WL1 to WL5 that illuminate and display the operation index provided on the upper housing 1 in the mobile phone according to the embodiment will be described. Although it is only an example, in the case of the mobile phone of the embodiment, when the control unit 44 detects that the upper housing 1 and the lower housing of the mobile phone are closed, the control unit 44 in FIG. As shown, each menu item for selecting a desired application program is displayed on the auxiliary display unit 11 provided in the upper housing 1 for a predetermined time such as 1 minute.

  The auxiliary display unit 11 is provided in such a manner that the entire auxiliary display unit 11 is housed in the upper housing 1 so that it cannot be seen from the appearance of the mobile phone. In the state in which the auxiliary display unit 11 is stored in the upper casing 1, the auxiliary display unit 11 is in close proximity to the display surface unit of the auxiliary display unit 11 (the surface unit on which each menu item is displayed) and the upper casing 1. 11 is housed in the upper housing 1. Moreover, the control part 44 displays each menu item with respect to the auxiliary | assistant display part 11 with a white character color, for example. For this reason, the light of a display object such as each menu item displayed on the auxiliary display unit 11 passes through the upper housing 1 and is visually recognized by the user.

  Also, the control unit 44 displays the menu item of the currently selected application program among the menu items displayed on the auxiliary display unit 11 with higher brightness than the menu items of other application programs. In the example shown in FIG. 7A, the control unit 44 controls the auxiliary display unit 11 to “music player (music player program)”, “television (television program)”, “camera (camera control program)”. , And “movie (camera control program viewer function)” menu items are displayed. Of these, the menu item “music player” displayed at the highest position is higher than the other menu items by default. An example displayed in luminance is shown.

  Further, when the control unit 44 detects that the upper casing 1 and the lower casing of the mobile phone are in the closed state, the light emission stored in the memory 43 together with the display control of the auxiliary display unit 11 as described above. Based on the control program, the light emitting units WL1 to WL5 that emit white light are controlled to emit light for a predetermined time such as 1 minute. As described with reference to FIGS. 2 and 3, among the light emitting units WL <b> 1 to WL <b> 5 that emit white light, the light emitting unit WL <b> 1 is a menu item selected from an operation menu or the like displayed on the auxiliary display unit 11. This is a light emitting unit for displaying on the protruding portion 5 of the upper housing 1 a determination key for designating the information processing corresponding to. In addition, among the light emitting units WL1 to WL5 that emit white light, the light emitting units WL2 to WL5 display the cross key for performing selection operation of each menu item displayed on the auxiliary display unit 11 and the protruding portion of the upper housing 1. 5 is a light emitting unit for displaying on the screen.

  And the white light from each light emission part WL1-WL5 which light-emits white light is diffused by the light-diffusion member 23 as shown in FIG. The light is emitted to the outside of the upper casing through the light transmitting section corresponding to the key and the cross key and the upper casing 1 formed of a transparent member. As a result, the determination key and the cross key are displayed on the upper housing 1 together with the menu items displayed on the auxiliary display unit 11 as shown in FIG.

  Next, when starting a desired application program, the user displays a menu item on the auxiliary display unit 11 and displays a cross key or a determination key on the upper casing 1 (= 1 above). The application program desired to be activated is selected by touching the up key or down key of the cross key. The controller 44 contacts the upper key, the lower key, and the decision key based on the detection output from the touch sensor 37 provided so as to cover the entire operation index of the upper housing 1 for the one minute or the like. The operation status is monitored, and each time an upper key contact operation is detected, display of each menu item is controlled with high brightness in the order of music player → movie → camera → TV → music player. The control unit 44 controls the display of each menu item with high luminance in the order of music player → TV → camera → movie → music player... Then, when detecting the touch operation of the enter key, the control unit 44 reads out the application program corresponding to the menu item displayed with high brightness when the touch operation of the enter key is detected, and controls the activation. To do.

  Next, the operation of the mobile phone when the user selects the music player menu item will be described. The music player can be selected using the cross key and the enter key as described above, and can also be selected by operating the operation unit 36 exposed when the mobile phone is opened. It has become.

  In the case of the mobile phone according to the embodiment, each music data stored in the memory 43 is added with metadata such as a song name, a song number, an album title, an artist name, and a performance time corresponding to each music data. ing. When detecting the selection operation of the menu item of the music player, the control unit 44 reads the metadata of each album title corresponding to each music data stored in the memory 43 from the memory 43, which is shown in FIG. As shown, the auxiliary display unit 11 provided in the upper housing 1 displays a list. The user selects a desired album title by touching the cross key provided in the upper casing 1 and designates the desired album title by touching the enter key.

  When the desired album title is designated by the touch operation of the determination key, the control unit 44 stores the music data corresponding to the album title displayed with high brightness when the determination key is touched. The metadata of each song name is read from the memory 43 and displayed as a list on the auxiliary display unit 11 as shown in FIG. The user selects a desired song name by touching the cross key provided on the upper casing 1 and designates music data to be played by touching the enter key.

  Next, when desired music data is designated by the user, the control unit 44 controls reproduction of the music data designated by the user based on the music player program stored in the memory 43, and Metadata such as a song name, song number, album title, artist name, performance time, etc. added to the music data being reproduced is read from the memory 43 and stored in the auxiliary display unit 11 as shown in FIG. indicate.

  When the user designates desired music data, the control unit 44 controls the light emitting units OL1 to OL5 that emit orange light based on the light emission control program stored in the memory 43. . As described with reference to FIGS. 2 and 3, among the light emitting units OL1 to OL5 that emit orange light, the light emitting unit OL1 includes a reproduction instruction key and a primary stop instruction key for music data currently being reproduced. Is a light emitting portion for displaying the image on the protruding portion 5 of the upper housing 1. The light emitting unit OL2 is a light emitting unit for displaying a volume up key (+ key) on the protruding portion 5 of the upper housing 1, and the light emitting unit OL3 has a volume down key (−key). It is a light emitting part for displaying on the protruding part 5 of the upper housing 1. The light emitting unit OL4 is a light emitting unit for displaying the previous song reproduction instruction key for designating reproduction of the music of the previous song number on the protruding portion 3 of the upper housing 1, and the light emitting unit OL5 is , A light emitting unit for displaying on the protruding portion 4 of the upper housing 1 a subsequent music reproduction instruction key for designating reproduction of the music of the next music number.

  And the orange light from each light emission part OL1-OL5 which light-emits orange light is spread | diffused by the light-diffusion member 23 as shown in FIG. In addition, the light transmission portion corresponding to the reproduction instruction key, primary stop instruction key, volume up key (+ key), volume down key (− key), and the like, and a transparent member are formed. The light is emitted out of the upper casing through the upper casing 1. As a result, as shown in FIG. 8B, the reproduction instruction key, the primary stop instruction key, the volume up key (+ key), the volume, and the metadata of the music data currently being displayed displayed on the auxiliary display unit 11 are displayed. A down key (−key) or the like is displayed on the upper housing 1.

Based on the detection output from the touch sensor 37, the control unit 44 monitors the presence / absence of a touch operation on any of the above keys. For example, when the contact operation of the primary stop instruction key is detected, the playback of the music data currently being played is controlled to be primary stop, and when the touch operation of the volume up key (+ key) is detected, Each time the contact operation is performed, the volume up control is performed one step at a time.

[Function of mesh member when light emitting part is not emitting light]
Next, when the user performs a music data playback end instruction operation or after the mobile phone is closed and the determination key or the cross key is displayed (see FIG. 7A), no matter what When a predetermined time such as 1 minute elapses without any operation, the control unit 44 performs non-display control of the display object displayed on the auxiliary display unit 11 provided in the upper housing 1, and The light emitting units OL1 to OL5 and the light emitting units WL1 to WL5 that have been controlled to emit light to display a determination key, a volume up key (+ key), and the like are controlled to be turned off.

  As described above, when the display object displayed on the auxiliary display unit 11 is controlled to be non-displayed, light emitted from the auxiliary display unit 11 to the upper housing 1 side, and emitted from the light emitting units OL1 to OL5 to the upper housing 1 side. The light emitted from the light emitting units WL1 to WL5 and the light emitted from the light emitting units WL1 to WL5 to the upper housing 1 side is eliminated, so that the color of the upper housing 1 visually recognized by the user is entirely the inner surface of the upper housing 1 The color of the ink member applied to the entire side.

  That is, when the display object displayed on the auxiliary display unit 11 is controlled to be non-displayed and the light emitting units OL1 to OL5 and WL1 to WL5 are controlled to be turned off, the menu items and cross keys that have been displayed on the upper housing 1 until then are displayed. Etc. disappears from the upper casing 1 and the user visually recognizes the color of the ink member applied to the entire inner surface of the upper casing 1 by the above-described printing process as the color of the entire upper casing 1. Will be.

  Here, when the light emitting units OL1 to OL5 and WL1 to WL5 are controlled to emit light, the operation indicators such as the cross key and the reproduction instruction key displayed on the upper housing 1 are in a state where printing is not performed as described above. The formed transparent color. For this reason, the light hitting the upper casing 1 passes through the transparent operation indicator portion, enters the upper casing 1, is reflected in the upper casing 1, and is operated again. By emitting the light from the index portion to the outside of the upper housing 1, there is a concern that the operation index is visually recognized by the user even when the light emitting units OL1 to OL5 and WL1 to WL5 are controlled to be turned off.

  However, in the case of the mobile phone according to the embodiment, when the light emitting units OL1 to OL5 and WL1 to WL5 are turned off, the mesh member 24 having the same color as the ink member used for the printing process of the upper casing 1 is (= upper The mesh member 24 having the same color as the housing 1) suppresses light from being incident into the upper housing 1 through the light transmission portion which is the portion of the operation index, and the mesh member 24 By reflecting the light that has entered the upper housing 1 through the light transmitting portion, light having the same color as the display portion is emitted to the outside of the upper housing 1.

As a result, when the light emitting units OL1 to OL5 and WL1 to WL5 are turned off, the color of the operation index, which is a transparent color, can be made the same color (assimilated) with the color of the upper housing 1. The operation indicator on the housing 1 can be viewed with great difficulty. Therefore, when the light emitting units OL1 to OL5 and WL1 to WL5 are turned off, the entire upper housing 1 can be visually recognized by the user as the color of the ink member. That is, for example, when the upper casing 1 is printed using a black ink member, if the light emitting units OL1 to OL5 and WL1 to WL5 are controlled to be turned off, the entire upper casing 1 is made black without any gaps to the user. It can be visually recognized. Further, for example, when the upper casing 1 is printed using an orange ink member, when the light emitting units OL1 to OL5 and WL1 to WL5 are controlled to be turned off, the entire upper casing 1 is made an orange casing without any gap. It can be visually recognized by the user.

[Effect of the embodiment]
As is clear from the above description, the cellular phone according to this embodiment includes a mesh member 24 between the operation indicator that is a light transmitting portion of the upper housing 1 and the light emitting portions OL1 to OL5 and WL1 to WL5. By interposing, the following effects can be obtained.

  1. At the time of light emission control of each of the light emitting sections OL1 to OL5 and WL1 to WL5, an operation in which the light from each of the light emitting sections OL1 to OL5 and WL1 to WL5 serves as a light transmission section through the mesh of each mesh member 24 Since the configuration is such that the light is emitted from the index, the amount of light (light reduction) from the light emitting portions OL1 to OL5 and WL1 to WL5 dimmed by the mesh member 24 can be extremely reduced, and the light is emitted from the operation index. The amount of light can be increased. Therefore, it is possible to clearly display display objects such as characters and figures corresponding to the shape of the operation index without driving the light emitting units OL1 to OL5 and WL1 to WL5 with high luminance. Further, since it is not necessary to drive the light emitting portions OL1 to OL5 and WL1 to WL5 with high luminance, power consumption can be reduced.

  2. By providing the mesh member 24 between the light emitting portions OL1 to OL5, WL1 to WL5 and the operation index, dot printing applied to the operation index can be made unnecessary. For this reason, since it is not necessary to perform this dot printing, it is possible to maintain a clear shape of the operation index and to clearly display a display object such as the operation index. Further, since dot printing can be eliminated, it is not necessary to use a printing apparatus with high printing accuracy, and it is possible to clearly display a display object such as the operation index while using an existing printing apparatus. .

  3. When the light emitting sections OL1 to OL5 and WL1 to WL5 are turned off, the mesh member 24 having the same color as the ink member used for the printing process of the upper casing 1 is incident on the upper casing 1 through the light transmitting section. And the net-like member 24 reflects the light incident through the operation index, thereby emitting light of the same color as the upper casing 1 to the outside of the upper casing 1. The color of the operation index is made to be the same color (assimilated) with the color of the upper housing 1. This makes it very difficult to visually recognize the operation indicator when the light emitting units OL1 to OL5 and WL1 to WL5 are turned off, and the presence of the operation indicator can be almost completely erased visually. This effect is very remarkable and uses a conservative wording such as “substantially complete”, but the presence of the operation index can be visually erased to such an extent that it cannot be seen at all.

  The applicant of the present invention conducted a prototype experiment of the mobile phone while changing the size of the mesh of the mesh member 24 (generally called “count”) and the color of the light diffusion member 23. The experimental results were obtained.

  First, using a 100-number mesh member having a coarse mesh and a transparent light diffusing member formed using polycarbonate resin, “similarity between the operation index and the casing when the light emitting part is turned off” '', `` Visibility of each light emitting part via operation indicator when light emitting part is turned off '' and `` Visibility of mesh member via operation indicator during light emission of light emitting part '' were confirmed. The effect could not be obtained.

  Next, using a 100-number mesh member with coarse mesh and a milky white light diffusing member, “similarity between the operation index and the case when the light emitting part is turned off”, “when the light emitting part is turned off” ”Visibility of each light emitting part via the operation indicator” and “Visibility of the mesh member via the operation indicator during light emission of the light emitting part” were confirmed. Despite the inconvenience of visually recognizing the mesh member, “Equalization of operation indicator and case when light emitting part is turned off”, “Visibility of each light emitting part via operation indicator when light emitting part is turned off” ”Was successfully obtained.

  Next, while using a mesh member having a medium mesh number of 250 and a transparent light diffusing member formed using a polycarbonate resin, “the operation index and the housing between the light emitting unit and the case are turned off. `` Same colorability '', `` Visibility of each light emitting part via operation indicator when light emitting part is turned off '', and `` Visibility of mesh member via operation indicator when light emitting part emits light '' “Color matching between operation indicator and case when light emitting part is turned off”, “Visibility of each light emitting part through operation indicator when light emitting part is turned off”, and “Operation indicator when light emitting part is turned on” Good effects could be obtained in all of the “visibility of the mesh member”.

  Next, while using a mesh member having a medium mesh number of 250 and using a milky white light diffusing member, the “similarity between the operation index and the casing when the light emitting part is turned off”, “the light emitting part After confirming the “visibility of each light emitting unit through the operation indicator when the light is turned off” and “visibility of the mesh member through the operation indicator at the time of light emission of the light emitting unit”, “the operation indicator when the light emitting unit is turned off” And the housing ”,“ Visibility of each light emitting unit via an operation indicator when the light emitting unit is turned off ”, and“ Visibility of a mesh member via an operation indicator when the light emitting unit emits light ” In all of these cases, good effects could be obtained.

  Furthermore, using a 300-number mesh member with a fine mesh and a milky white light diffusing member, the “similarity between the operation index and the case when the light emitting part is turned off”, “when the light emitting part is turned off” After confirming the “visibility of each light emitting unit via the operation indicator” and “visibility of the mesh member via the operation indicator during light emission of the light emitting unit”, “the operation indicator and the case when the light emitting unit is turned off” The same colorability with ”,“ Visibility of each light emitting part via an operation indicator when the light emitting part is turned off ”, and“ Visibility of a mesh member via an operation indicator when the light emitting part emits light ” And was able to get a very good effect.

  From such experimental results, the applicant of the present invention should select a mesh size that matches the size of the operation index (= light transmission portion) as the mesh size of the mesh member 24, Moreover, although the color of the light-diffusion member 23 may also be a transparent color, the opinion that a milky white can obtain a favorable effect has been obtained.

4). Since it can be realized with a simple configuration in which the mesh member 24 is provided between the light emitting portions OL1 to OL5, WL1 to WL5 and the operation index, it can be realized with a very inexpensive and simple configuration. Further, since the installation of the mesh member 24 requires a very small installation area, it can be applied without changing the device size of the mobile phone. Furthermore, since the mesh member 24 can be easily installed, it can be installed with almost no change in the configuration of the mobile phone.
