[Prior Art] In the era of information technology, electronic devices have been widely used in human daily life. Common electronic devices, including 3C products such as PDA, © computer, audio, etc., perform their specific tasks in accordance with user instructions. In addition to the function, the display panel further includes a display panel for displaying the current state of the electronic device, so as to inform the user of information about the current electronic device, such as power status, network connection status, or warning status. Please refer to the first figure, which is a schematic view of a display panel of a prior art electronic device. The display panel 1 is combined with a light source indicating area 101 of an electronic device 10. Referring to the second figure, it is a cross section of the display panel 1. The view includes a printed circuit board (PCB), a plurality of LEDs 12, a power line 13, a reflection sheet 14, a light equalizing plate 15, a diffusion sheet 16, and a display cover. 17. The printed circuit board 11 is respectively connected to the light-emitting diode 12 and the power line 13 and drives the light-emitting diode 12 to emit light by the electric energy provided by the power line 13. The reflective sheet 14 is disposed on the above. The bottom of the light-emitting diode 12 or the periphery thereof is intended to reflect the light source to avoid light leakage. The light-homogenizing plate 15 and the diffusion sheet 16 are disposed above the light-emitting diode 12, and its main function is to diffuse the light source and uniformize the light source. The cover plate 17 is disposed above the diffusion sheet 16 and has a transparent block 171 and a non-transparent block 172 on the surface thereof. The light emitted by the LED 12 can penetrate the 201018983 transparent block 171. The display panel uses the light and darkness of the light or the number of f times so that the user can understand the current state of the electronic device. However, the display panel of the prior art electronic device still has the following thicknesses of the display panel of the prior art: too many components of the prior art include: circuit board, polar body, / wide film, The light-shielding plate and the display cover plate, and the display panel formed after these components and 5 will become light and thin and short. The display panel of the conventional technology is expensive and the combination is not easy. The conventional technology has too many components, and the package is an expensive optical component, which is high in construction and difficult to combine. The cost of the panel is not the same as that of the c. The display panel of the conventional technology. When the two colors are used as the light source, there is a problem of color mixing: /, ❹ When some display panels need to be used in structural design, Ϊ There is a problem of color mixing between the original and the influence display product. [Invention] The present invention provides a display panel of an electronic device having fewer components, not only the surface of the surface, but also the surface of the display panel. The display panel of the present invention is combined with the light source of an electronic device to refer to the 201018983 display area, and includes a double layer board, a flexible circuit board and a display cover. The double-layer board includes a reflection board and a transparent board. The transparent board is formed above the reflection board and has a groove and a slope. The flexible circuit board has a side-illuminated LED, and the side-illuminated one-pole valley is placed at the groove of the transparent plate, and emits light toward the inclined surface, and the display cover covers the double-layer board And the upper portion of the soft ramp plate has a light transmissive block. Since the intensity of the light inside the transparent plate gradually decreases with the length of the distance traveled by the transparent plate, the thickness of the inclined surface of the transparent plate of the present invention decreases from near to far from the side-illuminated LED (that is, the bevel The closer to the groove, the greater the thickness, and vice versa, the thinner the thickness, the purpose of which is to make each light travel the same distance inside the transparent plate before exiting from the bevel, thereby obtaining a more uniform light output. Therefore, the display panel of the present invention only needs one transparent plate to achieve uniform light effect, and does not need to additionally provide a diffusion sheet and a homogenizing plate. Compared with the prior art, the invention not only has fewer components, is easy to assemble, and is overall. The thickness will also be thinner and the cost will be cheaper. In addition, in the display panel of the present invention, the double-layer board may have a plurality of grooves and a plurality of inclined surfaces, and the flexible circuit board has a plurality of side-illuminated light-emitting diodes, and are respectively accommodated in the concave surface. In the slot, the side-illuminated LEDs respectively provide light sources of different colors, and the side-illuminated LEDs are separated from each other by the reflector. Therefore, when the side-lit light-emitting diodes of different colors emit light at the same time, there is no problem of color mixing. It can be seen from the above that the display panel of the electronic device of the present invention can reduce the constituent elements and achieve the effect of uniformizing the light source, and the light source of different color systems can be displayed in 201018983. The invention further utilizes a reflector to block the problem of mixing colors. The specific embodiments of the present invention will be further described by the following embodiments and drawings. [Embodiment] The display panel of the present invention is coupled to a light source of an electronic device.
