The liquid crystal display product for note PC of the thin-shaped light weight which uses LED back light
About line-up
|
The toshiba Matsushita display technology corporation (president: Masaru Osamu Fujita), because thin shape, light weight, low electric power consumption is actualized for note PC as a liquid crystal display, LED (the light-emitting diode) 10.4 types, and 10.6 type liquid crystal displays which use back light were developed anew. Because of this, product line-up conversion was done at picture size of principal 7 types of 8.9 type ~13.3 types.
This corporation in 2005 October in the one for beginning note PC 11.1 type WXGA types of LED back light adoption commercialized in the world, started expanding the product line-up of liquid crystal display of the LED back light which combines ever since this corporation individual low temperature polysilicon technology.
LED back light, thin shape, light weight, high brightness, low is a merit of electric power consumption former CCFL (the cold cathode tube) in comparison with type. In addition, because it becomes with the mercury less, because it is kind in environment, drive voltage is low, it has possessed the merit which is superior in the design aspect and the safe aspect. Furthermore, vis-a-vis impact and the vibration it has possessed high durability.
As for picture size of the latest line-up with 8.9~13.3 type, as for resolution it is XGA and WXGA and WXGA+. It is, the product of the environmental correspondence which such as the light weight conversion is superior on the specification aspect, thin-shaped conversion of PC and long haul conversion of battery drive as a one for note PC of the Mobile use which is done to carry.
For PC of this corporation as a liquid crystal display product, it is the schedule where production ratio of LED back light type exceeds 50% on 07 latter halves.
In addition, other than adoption of LED back light, use of the thin-shaped glass below 0.3mm, in addition reduction and optimum arrangement design of the component are done for lightening, in the product of 10.4XGA with 120g and 12.1XGA 135g is actualized. And, we actualize thickness 2.5mm level because of this with the liquid crystal display product. While and, light weight, assuring thin-shaped conversion, it actualizes the high brightness of 200~300cd/m2 regarding brightness.
At this corporation, in order for us to be able to answer the needs of the customer precisely, continuation thin shape, the usability improvement of Mobile PC is supported positively by the fact that the product which actualizes lightweight/low electric power consumption consecutively is added to line-up.
