  • ELECTRONIC DEVICE
    Publication number: 20240135745
    Abstract: An electronic device has a narrow viewing angle state and a wide viewing angle state, and includes a panel and a light source providing a light passing through the panel. In the narrow viewing angle state, the light has a first relative light intensity and a second relative light intensity. The first relative light intensity is the strongest light intensity, the second relative light intensity is 50% of the strongest light intensity, the first relative light intensity corresponds to an angle of 0°, the second relative light intensity corresponds to a half-value angle, and the half-value angle is between ?15° and 15°. In the narrow angle state, a third relative light intensity at each angle between 20° and 60° or each angle between ?20° and ?60° is lower than 20% of the strongest light intensity.

  • System and method for automatically saving memory contents of a data processing device on power failure
    Patent number: 7634688
    Abstract: A system and method for automatically saving the contents of volatile memory in a data processing device on power failure. A secondary power supply is provided, which upon failure of the primary power supply supplies power long enough for all modified information stored in volatile memory to be written to a non-volatile memory device such as NAND flash in an AutoSave procedure. In the preferred embodiment modified sectors in volatile memory are flagged, and only modified sectors with a directory list are written to non-volatile memory during the AutoSave procedure.

  • Automatic detection of the bit width of a data bus
    Patent number: 7552267
    Abstract: A device employs a method for determining the data bus width of a non-volatile memory, such as NAND flash memory. The method performs at least two read operations on the non-volatile memory so as to test the changing of selected data bits. The method may be performed such that weak pull down and pull up operations are performed to test the data outputs of the non-volatile memory.
