A plurality of light-transmitting holes 122 passing through the inside of the body n 0 are disposed on the body 10 of the display unit 12. The light from the external light source can enter the inside of the body 10 through the light-transmitting holes 122. The body 10 further includes a plurality of concentrating elements 124 equal to the number of the transparent holes 122. The concentrating elements 124 may be conventional convex lenses, and each concentrating element 124 is correspondingly disposed on each of the transparent holes 122. 10 internal opening. The concentrating element 124 can receive and condense light entering by the light transmissive aperture 122. [0010] Please refer to FIG. 3 together, the light source device 20 can be configured to receive external light such as sunlight, and use the received light to excite the light source device 2 to generate a backlight that can be used to illuminate the display unit 12. . The light source device 2 package 098145238 Form No. A0101 Page 4 / 14 pages 0982077313-0 201122307 [0012] 00 [0013] 098145238 includes a light guiding element 22, a reflecting element 24 and a light oscillating medium 26 . The light guiding element 22 can be a flat mirror whose mirror portion is disposed as a reflecting surface toward the reflecting element 24. The light guiding element 22 includes an incident region 222 disposed at a peripheral portion and an exit region 224 disposed at the central portion. The incident region 222 is opposite to the light-transmitting hole 122 and the concentrating element 124, and the exit region 224 is opposite to the display unit 12. The incident region 222 is provided with a plurality of light entrance holes 226' for receiving the light from the light collecting member 124 and introducing them into the light source device 2''. The exit area 224 is provided with a plurality of light exit holes 228' for directing the backlight generated by the light source device 20 to illuminate the display unit 12. The radius of the pupil aperture 228 is smaller than the radius of the aperture 226 and the number of apertures 228 is greater than the number of apertures 226. The reflective element 24 can be a flat mirror having a mirrored portion as a reflective surface for reflecting light transmitted thereto back into the light source means 2A. The reflecting surface of the reflecting element 24 is disposed in parallel with the reflecting surface of the light guiding element 22, and a resonant cavity 28 is formed therebetween, and the optical vibrating medium 26 is filled in the resonant cavity 28. The light oscillating medium 26 can be a bismuth acid disk optical glass or other glass-based substrate having the same function, which can realize the population inversion under the illumination condition and generate the stimulated radiation strengthening effect of the light, thereby making it The photons with a relatively uniform exit direction are excited by the light introduced into the interior and are strengthened. Referring to FIG. 4 together, when the incident region 222 introduces light into the light source device 2 through the light entrance hole 226 and illuminates the light oscillating medium 26, the light will excite the light oscillating medium 26 to make the light oscillating medium. 26 occurs in the inversion of the number of particles and produces a stimulated radiation enhancement of the light, such that the light oscillating medium 26 produces a number of photons having different directions, Form No. 1010101, page 5 of 14 pages 0982077313-0 201122307 and is in the cavity 28 Under the action, the photons perpendicular to the reflecting surfaces of the light guiding element 22 and the reflecting element 24 are continuously reflected and oscillated by the light guiding element 22 and the reflective element 24, and the photons in other directions are suppressed. Finally, the photons generated by the optical oscillating medium 26 are formed in the resonant cavity 28 to form a reinforced light whose transmission direction is substantially perpendicular to the surface of the light guiding element 22 and the reflective element 24, that is, approximate to an ideal surface light source, and the light parallelism is relatively high. . Finally, the photon having a higher degree of parallelism is directly derived from the exit aperture 228 of the exit area 224 and can be used to illuminate the display unit 丨2. [0014] Please refer to FIG. 3 together. The second light source 30 can be mounted behind the display unit 12 or in the resonant cavity 28 to illuminate the display unit 12.

When the portable electronic phantom method receives external light, that is, the light source device 20 is inoperable, the second light source (10) ' can be activated to be directly supplied by the conventional battery supply to the display unit 12 in a conventional manner. Power supply required. It will be appreciated that a switch can be provided to select whether or not to cause the (four) second source 3〇. When the splicable electronic device igg cannot be received. When the light is on, the second light source 3 can be turned on by the switch 4 Q, that is, the backlight of the display unit 12 is provided in a conventional manner; when the portable electronic device can receive the appropriate external light, the Switch 4. The second light source 3G is turned off, and only the source of the material is used as the backlight source of the display unit 12 to save the battery power in the portable electronic device 1GG. 098145238 Form No. A0101 Page 6 of 14 0982077313-0 201122307 [0015] It can be understood that the light transmission hole 122 and the light collecting element 124 can also be replaced by other conventional light guiding structures, for example, the body 10 can be The other part is made into a transparent structure capable of receiving external light, and the light incident from the transparent structure into the body 10 is introduced into the incident region 222 of the light source device 20 by means of a conventional light guide plate and the like, and then introduced into the resonant cavity 28, that is, The backlight required for the display unit 12 can be formed in accordance with the above method. [0016] Obviously, the light source device 20 in the portable electronic device 100 can receive external light and excite the light source device 20 to generate the available light by using external light excitation before the additional power consumption is required. The backlight of the display unit 12 of the portable electronic device 100 is illuminated by Ο.
