Description

  The present invention relates to a light emitting thin plate having a plurality of visible areas, and more particularly to a light emitting thin plate having a plurality of visible areas whose structure is simplified.

  As shown in FIG. 1, a conventional mobile phone 1a has a main body 10a, a panel 11a corresponding to the main body 10a, and a plurality of light emitting diodes 2a distributed in the main body 10a. Has a plurality of operation buttons 111a, and the light emitted from the light emitting diode 2a passes through the panel 11a, and the user can identify the operation button 111a using the light transmitted through the panel 11a, Thus, the conventional mobile phone 1a can be used smoothly.

  The mobile phone 1a as described above utilizes the distribution of the plurality of light emitting diodes 2a to make it identifiable by the light beam that has passed through the plurality of operation buttons 111a on the panel 11a. For example, the display range of a family telephone, a keyboard, a portable computer, or the like has been expanded, and accordingly, there has been a tendency to increase the number of light-emitting diodes 2a. May be against the trend.

  SUMMARY OF THE INVENTION The first object of the present invention is to provide a light emitting thin plate having a plurality of visible areas which can form a plurality of visible areas according to predetermined needs.

  It is a second object of the present invention to provide a light emitting thin plate having a plurality of visible areas which can be reduced in weight and electric energy consumption is reduced.

  In order to achieve the above object, the present invention provides a kind of light emitting thin plate having a plurality of visible areas, including a thin plate having a thickness of 2 mm or less and at least one end disposed on at least one end of the thin plate. It comprises a kind of light emitting element and a plurality of pattern areas intermittently distributed on the thin plate body, thereby forming a plurality of visible areas.

  In the case of the light emitting thin plate having a plurality of visible areas according to the present invention, light can be emitted according to needs, and the object of lightening and reduction of electric energy consumption can be achieved.

  As shown in FIG. 2, the light-emitting thin plate 2 having a plurality of visible areas according to the present invention is applied to a display device 1. The display device 1 has a main body 10 and a panel 11 corresponding to the main body 10. The thin plate 2 having a plurality of visible areas is disposed on a thin plate 20 having a thickness of 2 mm or less, and at least one of the front end, the rear end, and both side edges of the thin plate 20. At least one kind of light emitting element 21 and a plurality of pattern areas 22 intermittently distributed on the thin plate member 20, wherein the pattern area 22 has at least one kind of stripes, projections, dents and the like. It has a pattern, and a light emitting diode (LED) or an organic light emitting diode (OLED) can be adopted as the light emitting element 21.

  In the case of the conventional light guide plate, mesh dots of different designs are produced and widely distributed on the plate body of the conventional light guide plate, and the purpose is to make the whole of the plate body of the conventional light guide plate already. It breaks the reflected light beam and reflects the light beam from one of the surfaces of the conventional light guide plate, aiming to uniformly guide and launch the light beam on the conventional light guide plate. .

  However, as shown in FIG. 3, the light emitting thin plate 2 having a plurality of visible areas according to the present invention guides and emits the light emitted from the light emitting element 21 from a predetermined area of the thin plate body 20 according to actual needs. Can respond to the actual needs of multiple visible areas. The present invention locks the light beam in the thin plate member 20 by a total reflection method, and when the user observes from outside the thin plate member 20, the thin plate member 20 does not release the light beam. This produces an image in which the plate body 20 is a dark object, so that a pattern is arranged in a plurality of predetermined areas of the thin plate body 20 to form a plurality of pattern areas 22, and the light rays are reflected or refracted. When the user observes from the outside of the thin plate member 20, the light-emitting thin plate 2 having the plurality of visible areas can be easily identified when the user observes the thin plate member 20 from the outside. The purpose is to meet the actual needs of emitting a light beam from a plurality of predetermined areas and having a plurality of visible areas forming a plurality of pattern areas 22.

  In the case where the light-emitting thin plate 2 having a plurality of visible areas has the same brightness of the derived light beams, the pattern area 22 close to the light-emitting element 21 can be set to a pattern with a small arrangement and a small size. In addition, the pattern area 22 which is away from the light emitting element 21 can be arranged densely and a pattern whose size can be enlarged.

  Further, a plurality of display areas are arranged on the panel 11 of the display device 1, each of which corresponds to a pattern area 22, and the display area has a code, character, pattern, or the like having a predetermined meaning. , Operation buttons 111 corresponding to those codes, characters, patterns, etc. can be arranged. As shown in FIG. 2, a mobile phone is adopted as the display device 1, and at least a plurality of preset areas of the operation buttons 111 arranged on the panel 11 of the mobile phone are combined with the light emitting thin plate 2 having a plurality of visible areas. When a kind of pattern is provided, the operation button 111 guides a light beam, so that the operation button 111 has discrimination and easy operability.

  In the above embodiment, the display device 1 is not limited to a mobile phone, but can be applied to a portable computer, a family telephone, a keyboard in a desktop computer, a personal digital assistant (PDA), an information home electric system, and the like.

  The light-emitting thin plate 2 having a plurality of visible areas according to the present invention arranges one or more patterns in a plurality of predetermined areas in the thin plate member 20, guides light rays according to the patterns, and sets a predetermined area according to actual needs. Satisfies the need to emit light and can meet the needs of multiple visible areas. Therefore, the thickness of the thin plate member 20 of the light emitting thin plate 2 having a plurality of visible areas can be reduced to 2 mm or less, and the purpose of reducing the weight of the light emitting thin plate 2 having a plurality of visible areas can be achieved. The light-emitting thin plate 2 having an area requires only one light-emitting element 21, which can satisfy the needs of a plurality of visible areas, and can reduce costs and reduce electric energy consumption.

  As described above, the present invention can achieve the expected purpose and effect, but the specific technical contents listed above are merely examples in which the present invention can be implemented, and the gist of any of the present invention Modifications and changes implemented based on the features are all included in the claims of the present invention.
