A display driver chip includes interface circuitry, image data processing circuitry, and drive circuitry. The interface circuitry is configured to receive first frame image data for a first frame image. The image data processing circuitry includes a buffer memory configured to store at least part of the first frame image data. The image data processing circuitry is configured to supply, based on the at least part of the first frame image data stored in the buffer memory, first display data for a first display area of a plurality of display areas of a display panel having a zigzag pixel arrangement. The drive circuit is configured to drive a display element in the first display area based on the first display data.

Device and method for driving a display panel

A display driver is disclosed that includes: an external interface circuit having input modes as interface modes to input display data. The display driver keeps the scan driving of a display panel stopped during a predetermined period until the driving of the display panel by display data input in the interface mode after switching is enabled in case that the interface mode of the external interface circuit is switched in the middle of driving the display panel based on display data input through the external interface circuit.

Display driver

A semiconductor device includes an analog front end and processing circuitry. The analog front end is configured to obtain capacitance detection data depending on capacitances of a plurality of sense electrodes of a liquid crystal display panel. The processing circuitry is configured to generate touch sensing data associated with a current touch sensing frame, based on capacitance detection data associated with the current touch sensing frame and capacitance detection data associated with a former touch sensing frame selected in response to a state in which the liquid crystal display panel is placed in the current touch sensing frame.

Device and method for touch sensing on display panel

A semiconductor device and a mobile terminal are described herein. In one example, a semiconductor device is provided that includes: a power-source part; an interface part; a logic part; and a driving part. In the semiconductor device, the power-source part includes a power-source-cutoff-detection circuit operable to detect a first state in which supply of an external power source is cut off. The logic part includes: a data-cutoff-detection circuit operable to detect a second state in which supply of stream data accompanied by synchronizing signals from outside the semiconductor device is cut off undesirably; and a control circuit operable to perform control for having the driving part cope with the power source cutoff with the power-source-cutoff-detection circuit detecting the first state or the data-cutoff-detection circuit detecting the second state.

This invention provides an electronic scale printer, and more particularly an electronic scale printer in which a printer is connected electrically to the electronic scale used in a department store or supermarket etc., and required data are printed on a printing sheet under an instruction from the electronic scale and issued from the printer. The invention provides a printer capable of issuing both a label and a receipt through one printing means and more particularly an electronic scale printer in which either a label or a receipt corresponding to the kind of printing sheet stored in a cassette is printed and issued under proper replacement of the cassette having printing sheet for label stored therein with a cassette having a printing sheet for receipt stored therein.
