    • 본발명은전자소자용유연성기판에관한것으로서, 기판의재질이비정질합금재질인고탄성비정질합금유연성기판인것을특징으로한다. 이때, 기판소재로사용되는비정질합금은대량연속생산에적합한상용합금기지고탄성(resilience) 비정질합금시스템인 IIA 족 Mg 계와 Ca 계, IIIA 족 Al 계, 그리고전이금속인 Ti 계, Zr 계, Hf 계, Fe계, Co계, Ni 계그리고 Cu계비정질합금중에서선택된하나의재질로, 공정가능온도를결정하는결정화온도가 200℃이상인것이바람직하다. 그리고기판의탄성력값이 1.5 MJ/m이상인것이바람직하고, 전자소자와의계면특성향상을위해열팽창계수(CTE)가 1~20ppm/℃작은범위인것인것이좋다. 본발명은, 유연성기판의소재로서고탄성비정질합금재질을사용함으로써, 고분자재질과금속재질기존유연성기판의단점은해소하고장점만을갖는유연성기판을제공할수 있는효과가있다.
    • 本发明涉及一种用于电子元件的柔性基板,更具体地说,涉及一种由非晶合金制成的具有高回弹性的柔性非晶合金基底。 非晶态合金是一种适用于连续大规模生产的具有高回弹性的商业合金基非晶合金体系,可以选自IIA族中的Mg-和Ca-型非晶合金,IIIAA族中的Al-型非晶态合金 ,以及作为过渡金属的Ti-,Zr-,Hf-,Fe-,Co-,Ni-和Cu-非晶态合金。 优选地,确定工艺允许温度的结晶温度为200℃以上。 并且,所述基材的回弹性优选为1.5MJ / m 3以上。 热膨胀系数(CTE)在1-20ppm /℃的小范围内,以提高与电子元件的界面性能。 本发明使用高弹性非晶合金作为柔性基板的材料来解决传统的聚合物材料和金属材料的柔性基板的缺点,并且仅保持优点。

    • PURPOSE: A method for providing a mobile internet protocol television service and a system thereof are provided to minimize average processing complexity when a user changes a channel to other channels in the same channel group by using a mobile terminal. CONSTITUTION: A base station executes channel grouping corresponding to channel preference of a user(S501). The base station distinguishes a channel group with a channel requested in a mobile terminal. The base station broadcasts a multicast stream to the mobile terminal(S503). The multicast stream includes a channel stream of the requested channel and channel streams of other channels included in the channel group. When a current channel and a changed channel are included in the same channel group, the mobile terminal decodes the channel stream of the changed channel in a stream of the current channel(S505). [Reference numerals] (220) Base station; (300) Mobile terminal; (AA) No; (BB) Yes; (S501) Grouping a channel according to the channel preference of a user; (S502) Power on for watching a TV; (S503) Transmitting channel stream corresponding to a currently watching channel and channels included in a channel group which is the same as the channel; (S504) Same group?; (S505) Displaying by performing decoding for channel stream corresponding to a channel to be changed; (S506) Transmitting a channel request message; (S507) Transmitting channel stream corresponding to the requested channel and channels included in a channel group which is the same as the channel; (S508) Displaying by performing decoding for the channel stream corresponding to the channel to be changed;
    • 目的:提供一种用于提供移动因特网协议电视服务的方法及其系统,以便当用户通过使用移动终端将信道改变到同一信道组中的其他信道时,使平均处理复杂度最小化。 构成:基站执行与用户的频道偏好对应的信道分组(S501)。 基站将信道组与移动终端中请求的信道进行区分。 基站向移动终端广播多播流(S503)。 多播流包括所请求的信道的信道流和信道组中包括的其它信道的信道流。 当当前信道和改变的信道被包括在同一信道组中时,移动终端在当前信道的流中解码改变的信道的信道流(S505)。 (220)基站; (300)移动终端; (AA)否 (BB)是的; (S501)根据用户的频道偏好对频道进行分组; (S502)看电视开机; (S503)与当前观看频道相对应的发送频道流和包含在与频道相同的频道组中的频道; (S504)同组?
