References now are made to FIG. 1 and FIG. 2, which are respectively depicting an exploded perspective diagram and a diagram of perspective view of assembly of the computer in accordance with the present invention. The laptop computer printed with the luminous full-color pattern is disclosed.
The laptop computer is essentially made of a host body 1 and a screen cover 2. The host body 1 and the screen cover 2 are pivotally connected. The host body 1 includes an input unit 11, an output unit 12, a power supply unit 13, and a mainboard 14, which are the essential elements usually included in a computer. It is characterized in that the screen cover 2 is essentially made of a liquid crystal display panel 21, an active light source 22, and a light-transmissive rear cover 24 on which a pattern 23 is printed. The liquid crystal display panel 21, the active light source 22 are respectively connected to the mainboard 14 of the host body 1, and therefore allowing the active light source 22 to be powered by the power supply unit 13 over the mainboard 14.
The light-transmissive rear cover 24 printed with the pattern 23 as described above is preferably made by a light-transmissive plastic material. For example, the preferred material is such as Polycarbonate (PC) SABIC 9925A which is featured to have high transparency and high strength.
While the laptop computer is in booting, in shutdown process, or in standby state, the light-transmissive rear cover 24 of the laptop computer allows the light generated by the active light source 22 disposed inside the cover 24 to pass through the cover 24 directly. Therefore, the pattern 23 printed onto the surface of cover 24 may be much clear and beautiful.
The pattern 23 on the rear cover 24 may be formed by various schemes. For example, the pattern 23 may be directly printed onto the rear cover 24, formed by a transfer printing process, or pasted with a patterned transparent film. Even though the different ways to form the pattern 23 onto the rear cover 24 may appear different visions, the present invention may be able to provide a certain level of visual effect. It is worth noting that the plateless transfer printing is the preferred solution to form the pattern 23.
