Patent number: 5552800Abstract: According to this invention, a panel controller converts display data having 64 gray scale levels for a color CRT output from an RAMDAC into display data having 57 gray scale levels to perform display driving of a color LCD. The panel display controller has a function of generating 7 intermediate pseudo gray scales between the base frames of R, G, and B signals by a frame rate control method in the color LCD having 8 base gray scale levels of each of the R, G, and B signals to generate (180K colors) display data having 57 gray scale levels and a function of generating 3 intermediate pseudo gray scales between the base gray scales of the signals by a dither method to generate (24K colors) display data having 39 gray scale levels. The selection of the frame rate control or the dither method and the selection of the 512-color, 180-K-color, or 24-K-color display are arbitrarily performed, or these selection operations are automatically performed in accordance with a display mode.Type: GrantFiled: August 23, 1994Date of Patent: September 3, 1996Assignee: Kabushiki Kaisha ToshibaInventors: Hiroshi Uchikoga, Hiroki Zenda, Hajime Shimamoto

Patent number: 5448260Abstract: A value obtained by adding a back porch period following a vertical sync signal output from a CRT controller to the total number of horizontal display lines of a display resolution is set in a register. A counter counts the value set in the register in synchronism with a horizontal sync signal, and outputs a scanning start signal to a Y driver. With this operation, when a designated display resolution is lower than the physical resolution of an LCD, the scanning start signal is output before scanning of all the physical display lines of the LCD is completed. As a result, upper and lower non-display portions on the LCD display screen are simultaneously scanned.Type: GrantFiled: June 16, 1994Date of Patent: September 5, 1995Assignee: Kabushiki Kaisha ToshibaInventors: Hiroki Zenda, Hajime Shimamoto

Patent number: 5300874Abstract: An intelligent power supply system for a portable computer, the computer having a central processing unit (CPU), and being operable in response to power supplied from at least two chargeable batteries or an alternating current (AC) adapter, includes means for detachably coupling the batteries to the computer and a PC-CPU for controlling power supply independent of the CPU. The PC-CPU has means for receiving battery select information for controlling power supply and generating a control signal. The power supply system further includes battery control circuit means, connected to the AC adapter and the batteries, for selecting and controlling the AC adapter or one of the batteries based on the control signal. Accordingly, the proper battery for the usage can be installed in the portable computer operable on battery power, and the computer can be operated continuously on the battery power for a long period of time.Type: GrantFiled: September 20, 1990Date of Patent: April 5, 1994Assignee: Kabushiki Kaisha ToshibaInventors: Hajime Shimamoto, Yasuhiro Ishida
