Description

  The present invention relates to a display device such as a liquid crystal display or an organic EL display, and relates to a display device having a non-rectangular display section.

  A conventional display device will be described below.

  Until now, CRT has been the mainstream display device, but in recent years, active matrix liquid crystal display devices (hereinafter referred to as LCDs), which are flat display devices, are becoming widespread because of their space-saving and power-saving properties. . The LCD is a display device that utilizes the light transmission property of liquid crystal, and does not emit light itself, but displays gradation by controlling the light of the backlight on the back in a transmission-blocking and intermediate state. Also, organic EL, which is the same flat display device, has begun to be used. The products to which these flat display devices are applied are mainly notebook personal computer screens and desktop personal computer monitors, but have recently begun to be used as display screens for TV receivers and mobile phones.

  In addition, as a display apparatus used for these apparatuses, the one where the display area ratio in the display side plane of an apparatus is large is preferable. The image display portion functions as a display device, and the so-called frame portion surrounding the image display portion is an area necessary for display, but is an area unnecessary for the user and is not preferable in terms of design. It is. If the frame portion that does not contribute to display is reduced, the efficiency of the display function is improved.

  LCDs that have been used in many devices so far have been narrowing the frame area for each device. This is especially true for notebook computers. The frame area of the original notebook computer was very large, but the frame area of the current notebook computer has become very small.

  In this frame portion, wirings, circuits, and semiconductor elements necessary for displaying the LCD are arranged. For example, in [Patent Document 1], the wiring pattern between the semiconductor elements is made efficient. It is described that the frame is narrowed and the cost is reduced. In [Patent Document 2], a part of the circuit for driving the LCD is built in the panel, and ITO wiring is used to further reduce the circuit area, thereby further reducing the frame and yield. It is stated that improvement is possible.

  In addition, although the example of the display apparatus using a liquid crystal was described, the same approach is made also in the display apparatus using an organic EL element.

JP 11-337966 A JP-A-11-190857

  However, the above-described efforts for narrowing the frame are mainly applied to a display device whose image display area has a rectangular outer shape. In a display device having a rectangular external shape, the external shape of the display unit can be formed in the orthogonal direction of pixels arranged in an orthogonal matrix.

  On the other hand, in recent years, a display device having a non-rectangular outer shape has also been studied. For example, the dashboard of a car is preferably non-rectangular, and there may be an oval or heart-shaped mobile phone.

  In such an image display device having a non-rectangular display unit, when it has a built-in circuit for signal wiring and a built-in circuit for scanning wiring, each built-in circuit area and wiring area, and further, a built-in circuit for signal wiring and scanning wiring Overlapping areas of the built-in circuit for the output appear, and as a result, there arises a problem that the frame area increases. In the above Patent Documents 1 and 2, the arrangement of the built-in circuit in the case where the outer shape is non-rectangular is not studied.

  The object of the present invention is to solve such problems and problems. That is, an object of the present invention is to provide a display device having a non-rectangular image display area and a built-in driving circuit, a display device having a small frame area outside the display region and a small wiring delay, and those It is to provide a display device that can be easily designed.

  In order to solve the above problems, in the present invention, a plurality of pixels arranged in an orthogonal matrix, a plurality of scanning wirings connected to the plurality of pixels, and a plurality of scanning wirings connected to the plurality of pixels. A plurality of signal wirings arranged in an orthogonal matrix, a pixel display region composed of the plurality of pixels and having a non-rectangular outer shape, and driving the plurality of scanning wirings along the outer shape of the pixel display region. An image display device comprising: a built-in circuit for scanning wiring formed; and a built-in circuit for signal wiring that drives the plurality of signal wirings and is formed along an outer shape of the pixel display area. Among the contacts in contact with different sides of the outer shape of the pixel display region and an arbitrary rectangle circumscribing the outer shape of the pixel display region, one of the two contacts having the shortest distance between the contacts along the outer shape of the pixel display region is used as a starting point. ,in front A configuration of an image display device scanning lines for internal circuit and the signal lines for internal circuit are disposed.

  As will be described later, when one of the scanning wiring circuit and the signal wiring circuit is not built-in, it is possible to adopt a configuration in which the wiring lead-out portion is arranged at the position of the built-in circuit.

  Further, the scanning wiring built-in circuit and the signal wiring built-in circuit are arranged so as to overlap each other between the two contacts having the shortest distance, starting from different contacts of the two contacts having the shortest distance. A configuration can also be taken. Further, the scanning wiring built-in circuit and the signal wiring built-in circuit may be configured to be arranged with a contact point contacting the rectangular side different from the two contact points having the shortest distance as an end. Further, the scanning wiring built-in circuit and the signal wiring built-in circuit may be formed along the outer shape of the pixel display region between three contact points in contact with different sides of the rectangle.

  Here, the non-rectangular shape of the image display area is not a square with all angles of 90 degrees as in the conventional image display area, but a rhombus, a curved curve, or a circle or ellipse. It represents that the outer shape. In addition, “start” and “end” are defined, but if one end of the area where the scan wiring built-in circuit and signal wiring built-in circuit are formed is the start, the other end is represented as the end. Shall be.

  Further, as another configuration of the present invention, the contact point that touches a different side of the outer shape of the pixel display region and an arbitrary rectangle circumscribing the outer shape of the pixel display region includes a right-angle portion of the rectangle, It is also possible to adopt a configuration of an image display device in which the scanning wiring built-in circuit and the signal wiring built-in circuit are arranged starting from one of the two contacts constituting the smallest area.

  Further, the contact point that contacts different sides of the outer shape of the pixel display region and an arbitrary rectangle circumscribing the outer shape of the pixel display region includes a contact point having the largest curvature radius of the outer shape of the pixel display region that is in contact with the pixel display region, It is also possible to adopt a configuration of an image display device in which the scanning line built-in circuit or the signal wiring built-in circuit is arranged with a contact at a side perpendicular to a side where the contact having the largest radius of curvature is in contact as a start and end.

  In addition, the pixel display area has an acute angle on an outer shape, and on the different sides of the outer shape of the pixel display area and an arbitrary rectangle circumscribing the outer shape of the pixel display area so that the acute angle is one vertex. Of the contact points in contact, the image display device may be configured such that the scanning wiring built-in circuit and the signal wiring built-in circuit are arranged starting from the contact at the acute angle.

  According to the present invention, since the frame area of a non-rectangular display device can be reduced, a display device with good design and high functional efficiency can be provided.

  The best mode for carrying out the present invention will be described below.

  FIG. 1 shows a simplified diagram of a display device having a non-rectangular display portion. In FIG. 1, the display unit is represented as an ellipse, but is represented as an example of a display unit having a non-rectangular outer shape.

  In the display device 100 of FIG. 1, the outer shape of the pixel display region 101 that is the image display region is an ellipse, and the outer shape of the glass in the display device 100 is also an ellipse. The display device 100 in this embodiment is a liquid crystal display device. Although not shown in FIG. 1, in the pixel display area 101, the pixels are arranged in an orthogonal matrix, and the signal lines and the scanning lines are also arranged in an orthogonal form in the same manner as a normal liquid crystal display device.

  The signal wiring is driven from the driver 102 via the signal wiring built-in circuit 104 and the signal wiring lead wiring 103, and the scanning wiring is driven via the scanning wiring built-in circuit 106 and the scanning wiring lead wiring 105. 102 is driven.

  In FIG. 1, unlike the conventional liquid crystal display device, the pixel display area 101 has an oval outer shape. Therefore, the signal wiring built-in circuit 104 and the scanning wiring built-in circuit 106 are also adjacent to the pixel display area 101. Take the arrangement. In this case, since a signal is sent to each pixel arranged in an orthogonal matrix, the signal wiring built-in circuit 104 and the scanning wiring built-in circuit 106 overlap in a part of the frame. This is represented by an overlapping area 107 in FIG. 1, and the more this area, the larger the frame area, that is, the area not used for display. In order to reduce such enlargement of the frame area, the present embodiment has the following configuration.

  FIG. 2 shows an overview of the display device in this embodiment. In the display device 100 according to the present embodiment, the outer shape and the outer shape of the pixel display area 101 are elliptical as in FIG. 1, but the place where the signal wiring built-in circuit 104 and the scanning wiring built-in circuit 106 are arranged. Is different.

  A rectangle indicated by a broken line in FIG. 2 is a rectangle 151 circumscribing the pixel display region 101. A rectangle circumscribing an arbitrary shape has at least four contact points, but the circumscribed rectangle 151 illustrated in FIG. 2 is a distance along the outer shape of the image display area between any two contact points contacting different sides. Is arranged to be the shortest. In FIG. 2, the distance 108 along the outer shape of the image display area is the shortest for the first contact 152 and the second contact 153. The signal wiring built-in circuit 104 extends along the pixel display region 101 from the second contact point 153 to the third contact point 154 that is in contact with the other side of the circumscribed rectangle 151 through the first contact point 152. Is arranged.

  The scanning wiring built-in circuit 106 extends along the pixel display region 101 from the first contact 152 through the second contact 153 to the fourth contact 155 in contact with the last side of the circumscribed rectangle 151. It is a feature of the present embodiment that is arranged.

  Thus, by arranging the signal wiring built-in circuit 104 and the scanning wiring built-in circuit 106, the outer edge of the pixel display area where the signal wiring built-in circuit 104 and the scanning wiring built-in circuit 106 are arranged in an overlapping manner is very small. Less.

  Here, the circumscribed rectangle 151 shown in FIG. 2 indicates the arrangement direction of the pixels arranged in the orthogonal matrix in the pixel display area 101, and the orthogonal sides of the circumscribed rectangle 151 are displayed in the pixel display area 101. By arranging each built-in circuit at the projected location, orthogonal matrix driving can be realized. In this case, in order to minimize the overlapping arrangement of the built-in circuits, the circumscribed rectangle 151 is arranged so that the distance along the outer shape of the image display area between the contacts on the orthogonal sides (between adjacent contacts) is minimized. It is a feature.

  In this embodiment, since the outer shape of the pixel display area 101 is symmetrical, the distance between the first contact 152 and the second contact 153 and the distance between the third contact 154 and the fourth contact 155 are equal. There is no problem even if the arrangement locations of the signal wiring internal circuit 104 and the scanning wiring internal circuit 106 are changed.

  It is also possible to adopt a configuration in which only the signal wiring built-in circuit 104 is built in, and the scanning wiring side does not have the circuit for scanning wiring built in, and the wiring is drawn out as it is. Also in this case, if the overlapping area between the signal wiring built-in circuit and the wiring drawing area for the scanning wiring is large, it is necessary to route the detour wiring accordingly, and the frame area is increased. Therefore, even in the configuration in which only the signal wiring circuit is built in, the signal wiring built-in circuit is arranged as the signal wiring built-in circuit 104 in FIG. 2, and the scanning wiring wiring drawing region is formed in the scanning wiring built-in circuit 106 in FIG. By arranging, the effect of reducing the frame area can be obtained. The same applies to the case where only the circuit for scanning wiring is incorporated.

  As described above, in this embodiment, the frame area can be further reduced by shortening the overlapping arrangement of the signal wiring built-in circuit and the scanning wiring built-in circuit as much as possible. Accordingly, a display device with a small frame area, a small wiring delay, and an easy design can be provided.

  FIG. 3 shows an overview of the display device in this embodiment. The display device 100 according to this embodiment is different from the configuration of FIG. 2 in that the outer shape and the outer shape of the pixel display region 101 are heart-shaped. In the present embodiment, among the regions surrounded by the circumscribed rectangle 151 and the pixel display region 101, the arbitrary region including the right-angled portion of the circumscribed rectangle 151 has the smallest area so that the area of the circumscribed rectangle 151 is minimized. Arrangement is decided. In FIG. 3, the first contact 152 and the circumscribed rectangular right-angle portion 109, the second contact 153 and the circumscribed rectangular right-angle portion 109, and the first contact 152 and the second contact 153 are the outer shapes of the image display area. The circumscribed rectangle 151 is arranged so that the area of the region B surrounded by the line connected along the line is the smallest.

  The signal wiring built-in circuit 104 is arranged along the outer shape of the pixel display region from the second contact 153 through the first contact 152 to the third contact 154, and the scanning wiring built-in circuit 106 is connected to the first contact circuit 154. The contact 152 is disposed along the fourth contact 155 through the second contact 153.

  Also by arranging the built-in circuit as described above, it is possible to reduce the area where the two circuits are overlapped, and it is possible to reduce the area of the frame portion of the part. Also in this embodiment, even if a conventional circuit is used as the built-in circuit, the frame area can be reduced, and the wiring delay can be reduced also as a wiring drawing area instead of the built-in circuit area. is there.

  As described above, the frame region can be further reduced by shortening the overlapping arrangement of the signal wiring built-in circuit and the scanning wiring built-in circuit. Accordingly, a display device with a small frame area, a small wiring delay, and an easy design can be provided.

  In the configurations of the first and second embodiments, the arrangement of the built-in circuits is devised so as to reduce the overlapping area of the signal wiring built-in circuit and the scanning wiring built-in circuit as much as possible. On the other hand, in the present embodiment, it is devised to arrange the circuit with a built-in signal wiring or the circuit with a built-in scanning wiring so as not to be placed in an area where the design difficulty becomes high due to additional wiring or the like.

  FIG. 4 shows an overview of the display device in this embodiment. In the display device 100 according to the present embodiment, the outer shape and the outer shape of the pixel display area 101 are elliptical as in FIG. 2, but the signal wiring built-in circuit 104 and the scanning wiring built-in circuit 106 are located. Is different.

  In the present embodiment, the contact point 156 having the largest radius of curvature of the outer shape of the pixel display region 101 in contact with the pixel display region 101 and the contact points on different sides of the rectangle 151 circumscribing the pixel display region 101 is included. The signal wiring built-in circuit 104 is arranged along the outer shape of the pixel display area between two contacts (second contact 157 and third contact 158) that are in contact with a side perpendicular to the side with which the contact 156 having the largest radius contacts. It is characteristic that it is.

  The scan wiring built-in circuit 106 is disposed between the contact 156 having the largest curvature radius and the fourth contact 159 in contact with the side opposite to the side in contact with the contact.

  The pixel display area 101 is composed of a plurality of pixels arranged in an orthogonal matrix in the direction of the circumscribed rectangle 151. Here, since the pixel display area 101 is elliptical, the number of rows (or pixel columns) of a plurality of pixels changes in a certain area. In general, in a portion where the radius of curvature of the pixel display region 101 is large, the frequency of change of rows (or pixel columns) of pixels arranged in an orthogonal matrix is small, and it is rare that pixels change simultaneously in two or more rows. . On the other hand, in a portion where the polar radius of the pixel display area is small, the frequency of the change in the number of pixel rows (or pixel columns) increases, and two or more rows change simultaneously.

  When the signal wiring built-in circuit 104 is modularized and used in two stages in the signal wiring extending direction, when two or more pixels are simultaneously reduced, the input / output wiring between the circuits is not automatically connected. Additional wiring is required. This shows that the time required for design increases and the difficulty increases. Therefore, when using a built-in circuit module that is modularized in units of pixels as in the present embodiment, it is better to place it in a region with a radius of curvature as large as possible.

  For the above reasons, in this embodiment, the signal wiring built-in circuit 104 is arranged around the place where the radius of curvature in the outer shape of the pixel display region 101 is large. Thereby, the time required for the design can be shortened, and the difficulty of the design can be reduced. In the present embodiment, the signal wiring built-in circuit is arranged in the region having a large curvature radius, but a scanning wiring built-in circuit may be arranged. Which part is used for a region with a large radius of curvature depends largely on the number of modules used in consideration of the wiring load. Circuits with a small number of modules used may require additional wiring due to pixel row (column) reduction. Therefore, it is desirable to use it in a region with a large radius of curvature.

  Also in the present embodiment, the built-in circuit used in the region having a large radius of curvature may be a conventional built-in circuit. In this case as well, there is an effect of simplifying the design by reducing the additional wiring. However, in this case, it is desirable that the scanning wiring drive circuit area is not a built-in circuit but a wiring drawing area.

  As described above, by arranging the arrangement positions in consideration of the outer shape of the pixel display region, it is possible to shorten the design time and reduce the difficulty. As a result, a display device with a small frame area, a small wiring delay, and an easy design can be provided.

  FIG. 5 shows an overview of the display device in this embodiment. In the display device 100 in this embodiment, the outer shape and the outer shape of the pixel display area 101 are heart-shaped as in FIG. 3, but the place where the signal wiring built-in circuit 104 and the scanning wiring built-in circuit 106 are arranged. Is different.

  In the present embodiment, the outer shape of the image display area 101 has an acute angle, and a point between the contact 161 that is in contact with a side that does not include the acute vertex 160 of the circumscribed rectangle 151 having the acute angle as one vertex and the acute vertex. Further, a signal wiring built-in circuit 104 and a scanning wiring built-in circuit 106 are arranged. In FIG. 12, the signal wiring built-in circuit 104 is arranged between the acute angle vertex 160 and the first contact 161, and the scanning wiring built-in circuit 106 is arranged between the acute angle vertex 160 and the second contact 162.

  Thereby, there is no region where the signal wiring built-in circuit 104 and the scanning wiring built-in circuit 106 are arranged in an overlapping manner, and the enlargement of the frame area in the overlapping arrangement is eliminated. With such an arrangement, the frame area can be minimized when a conventional built-in circuit is used as each built-in circuit. Note that even if one of the built-in circuits is used as a wiring lead-out portion, it is not necessary to perform detour wiring, so that the frame area can be reduced and wiring delay can be reduced.

  As described above, also in the present embodiment, the design time can be shortened and the difficulty can be reduced by considering the arrangement position in consideration of the outer shape of the pixel display region. A display device with a small frame area, a small wiring delay, and an easy design can be provided.
