Patent number: 8350165Abstract: A flexible tablet is disclosed, and particular disclosed a flexible tablet having both of a hard housing structure and a soft housing structure. The flexible tablet fix a control board in the hard housing structure for preventing the control board form bending and break resulting from external force. In the flexible tablet, the soft housing structure is applied instead of the hard housing of a conventional tablet to fix a sensing board therein. Therefore, the soft housing structure and the sensing board are integrated to form a flexible writing member of the flexible tablet. As a consequence of foregoing structure, the tablet is flexible and convenient to be stored and carried, and the cost of the tablet is reduced.Type: GrantFiled: August 11, 2009Date of Patent: January 8, 2013Assignee: Waltop International CorporationInventors: Chung-Fu Mao, Chung-Wen Hsu, Chien-Chia Lien, Kuang-Yao Hsieh

Patent number: 8339343Abstract: The present invention discloses a liquid crystal display (LCD) device. The LCD device comprises an upper substrate and a lower substrate. Every two data lines and two scan lines define two pixels. Each pixel comprises a pixel electrode and a transistor, and a biased electrode is arranged under a slot between two pixel electrodes of the two pixels. When positive frame, the voltage of the biased electrode, VE, is greater than the voltage the pixel electrode, VP; when negative frame, the voltage of the biased electrode, VE, is smaller than the voltage the pixel electrode, VP.Type: GrantFiled: December 30, 2008Date of Patent: December 25, 2012Assignee: Hannstar Display Corp.Inventor: Ching-Chao Chang

Patent number: 8269751Abstract: A photo element includes a photo thin film transistor (TFT), a switch thin film transistor, and a compensation thin film transistor. A bias line provides a bias voltage to the photo TFT. The photo TFT generates a photo-induced current under an illuminated environment. A first switch line provides a voltage to open the switch TFT, and thus the photo-induced current is read out through a readout line. A second switch line provides compensation current to open the compensation TFT. The compensation current applies a reverse-biased stress to the photo TFT; therefore the threshold voltage and sensitivity of the photo TFT can be maintained.Type: GrantFiled: November 26, 2009Date of Patent: September 18, 2012Assignee: Hannstar Display Corp.Inventors: Ting-Chung Liu, Po-Yang Chen, Hsien-Tang Hu, Chien-Chih Hsiau
