A method for performing adaptive locking range management, an associated data storage device and a controller thereof are provided. The method may include: receiving a security command from outside of the data storage device, wherein the security command is related to changing an old locking range into a new locking range; obtaining a start Logical Block Address (LBA) and a length value of the new locking range according to the security command; determining whether the start LBA of the new locking range is less than an end LBA of the old locking range, and determining whether an end LBA of the new locking range is greater than a start LBA of the old locking range; and in response to both determination results being true, performing data trimming on any respective non-overlapped portions of the new locking range and the old locking range.

Method for performing adaptive locking range management, associated data storage device and controller thereof

A security extension design for non-volatile memory is shown. There is an in-system program loaded into the non-volatile memory. A memory controller downloads the in-system program to a data register to provide base firmware code, a function pointer structure and security firmware code on the data register. The memory controller executes the base firmware code, and security functions of the security firmware code are called by the base firmware code through information recorded in the function pointer structure and thereby the memory controller is switched to operate the non-volatile memory at a higher security level. The security firmware code uses an application programming interface (API) and is compatible with multiple projects.

Data storage device and non-volatile memory control method, with security extension

A touch display device includes a display area and a non-display area and further includes a touch electrode layer; wherein a plurality of sensing electrodes is configured in the electrode layer; wherein each sensing electrode extends from the display area to the non-display area and is coupled to a driver chip via a connection structure; wherein the connection structure locates in the non-display area.

Touch display device

The present invention provides a circuit for controlling a color sequential liquid crystal display (LCD) and a method for controlling the same. The control circuit comprises a light-source driving circuit, a data driving circuit, and a scan driving circuit. The light-source driving circuit produces a driving signal for controlling the color sequential LCD to produce backlight with different colors. The data driving circuit produces a data signal and includes a plurality of data pulses. The scan driving signal produces a scan signal and includes a plurality of scan pulses corresponding to the plurality of data pulses, respectively. By controlling the pluralities of data pulses and scan pulses and the backlight, the color sequential LCD will display an image. The voltage levels of the pluralities of data pulses and scan pulses change according to different images. Thereby, power consumed by the control circuit can be reduced. In addition, color-mixing problems will be reduced according to the present invention.

Circuit for controlling color sequential liquid crystal display and method for controlling the same

A control IC (integrated circuit) for color sequential liquid crystal displays (LCD) is revealed. The control IC includes an interface for receiving a command and at least one display data and a timing generator to generate a scan timing signal, a data timing signal, and a driving timing signal. According to the scan timing signal, a scan driving circuit generates a scan signal that is sent to the color sequential LCD. In accordance with the data timing signal, a data driving circuit receives the display data for generating a data signal sent to the color sequential LCD. According to the driving timing signal, a light-source driving circuit generates a plurality of driving signals sent to the color sequential LCD so as to generate a plurality of color backlights. In accordance with the scan signal, the data signal and the plurality of backlights, the color sequential LCD displays a frame.
