The invention discloses a backlight module and a light-emitting diode (LED) display. The backlight module comprises a light source module with a luminous surface and a back panel, a reflecting piece and a light guide plate which are sequentially stacked, wherein one end of the light guide plate bends and extends to the back panel direction to form a bending part of which the outer surface is not transparent; an end face at the tail end of the bending part is a light entrance surface; and the light source module is fixed on the edge of the back panel, and the luminous surface of the light source module is opposite to the light entrance surface. According to the backlight module, because the light source module is positioned on the outer side of the back panel, the generated heat is directly dispersed outwards and is not collected inside the back panel; and therefore, the radiating efficiency is improved, and all problems caused by bad radiation of the backlight module in the traditional technology are solved; and meanwhile, the light source emitted from the light source module does not directly enter the side face of the light guide plate and enters the light entrance surface of the bending part, after the light is reflected and fully mixed inside the bending part, and the light source enters the backlight module; and therefore, the dark space inside the backlight module is eliminated, and the backlight effect is improved.

A keypad panel assembly having a laterally-illuminated keypad surface is arranged on an electronic device. The keypad panel includes a light-guiding plate and a panel. The light-guiding plate has a carrier thereon. One side surface of the carrier is provided with a plurality of protruding strips. Each protruding strip is provided with a plurality of light-guiding particles at positions corresponding to the other side surface of the carrier. The top surface of the protruding strip is provided with a reflective layer. The panel is arranged on one side surface of the carrier, and is provided thereon with a plurality of rectangular keypads. One side surface of each keypad is provided with an icon, and a plurality of hollowed portions is provided between each keypad and the panel. Each hollowed portion encloses a rectangular shape and corresponds to the protruding strip of the carrier. After the protruding strip passes through the hollowed portion, the height of the protruding strip is larger than those of the keypad and the icon. After the light generated by a backlight source of the electronic device is introduced from one side of the light-guiding plate, the light-guiding particles focus the light on the protruding strip. Then, the light illuminates the keypad surface from both sides of the protruding strip, so that a user can see the icon displayed on the keypad surface clearly.

Meanwhile, the light source can be assembled more conveniently through the light guide plates with the structures, so that the assembling process of the backlight source is simplified greatly, and the rejection ratio in the assembling process of the backlight source is greatly lowered.

The invention relates to a method for plating a metal on the surface of an insulating base material. The method comprises the following steps: alternately touching the surface of the insulating base material with polycations and polyanions to produce a modified surface; touching the modified surface with an aqueous solution containing permanganate ions to form a manganese dioxide adsorption layeron the modified surface; forming a conductive polymer layer on the surface of the manganese dioxide adsorption layer; and performing plating on the surface of the conductive polymer layer to form a metal layer. According to the method, by means of the alternate deposition of the polycations and polyanions on the surface of the insulating base material to form a firmly combined coating layer withthe surface of the base material, after a thin film with a certain thickness is uniformly formed on the surface by means of the modification and adsorption, under the same metal plating solution and plating conditions, the deep plating ability and the dispersing ability of the plating solution are greatly improved, the obtained metal plating layer has the characteristics of flatness, uniformity and good backlight effect, and the phenomena of hole breakage and that the Plating metal layer at a certain site in the hole is too thin are avoided.
