Abstract: There is provided a failure identification method of an optical navigation device including the steps of: constructing a fixed noise map according to image frames captured by an image sensor; calculating a feature value of the fixed noise map; identifying whether the fixed noise map is uniform or not according to the feature value; and generating an alert signal when the fixed noise map is non-uniform for indicating failure of the optical navigation device.

Abstract: Disclosed are a mobile terminal having a rollable touch screen, and a method of controlling the same. The mobile terminal includes: a touch screen configured to be rollable; a first body portion connected to a first end of the touch screen and configured to accommodate the touch screen in a rolled state; a second body portion connected to a second end of the touch screen; a sensing unit configured to sense at least one region of the touch screen exposed external to the first body portion; and a controller configured to cause the touch screen to display a first icon on a display region, the display region corresponding to the sensed at least one region, wherein the first icon corresponds to a first application which supports a screen ratio of the display region, wherein the first application is one of a plurality of applications installed at the mobile terminal.

Abstract: An in-cell touch panel and a display device are provided, and the in-cell touch panel includes: an upper substrate and a lower substrate arranged oppositely to each other; a plurality of self-capacitance electrodes arranged in a same layer and insulated from each other at a side, facing the lower substrate, of the upper substrate or a side, facing the upper substrate, of the lower substrate; a shielding electrode provided at a side, facing the lower substrate, of each of the self-capacitance electrodes, which is insulated from the shielding electrode; and an insulating layer arranged between each of the self-capacitance electrodes and the shielding electrode. Such an in-cell touch panel may isolate the touch detection signals applied to the self-capacitance electrodes from the display signals, so as to avoid mutual interference therebetween.

Abstract: The present invention discloses a touch display device and an electronic apparatus. The touch display device includes a display unit and a touch unit. The touch unit include a transparent electrode, and a pattern of the transparent electrode includes a plurality of first touch electrodes and a plurality of dummy electrodes; and each of the dummy electrodes includes at least two columns of dummy sub-electrodes, each of the columns of dummy sub-electrodes includes a plurality of dummy sub-electrodes arranged in the first direction with each of the dummy sub-electrodes extending in the first direction, there is a sub-slit formed between every two adjacent dummy sub-electrodes in each of the columns of dummy sub-electrodes, and at least a part of the sub-slits of at least two adjacent ones of the columns of dummy sub-electrodes are arranged staggeredly in the first direction. The electronic apparatus includes the touch display device.

Abstract: According to an aspect, a display device with a touch detection function includes: a display region; a plurality of drive electrodes; a control device; a touch detection electrode that is opposed to the drive electrodes and forms capacitance with respect to the drive electrodes; power supply wiring arranged in a frame region positioned outside the display region; and a plurality of drive electrode scanning units that select the drive electrode to be coupled to the power supply wiring. when the drive electrode scanning unit simultaneously selects the drive electrodes of which number is equal to or larger than the number of pieces of the power supply wiring, the control device supplies a touch driving signal that is multiplexed based on a certain code to each of the selected drive electrodes.

Abstract: In a motor vehicle having a plurality of display devices, a gaze direction of a driver of the motor vehicle is detected and used to check whether the driver has directed his gaze to a display region of the display devices for at least a predefined gazing duration. If the gaze has been directed to one of the display regions of one of the display devices for at least the predefined gazing duration, an interaction mode of an operating device for controlling the relevant display device is activated. An extended gazing duration which is longer than the predefined gazing duration is predefined for at least one of the display devices and for this display device, the interaction mode is activated only if it has been detected that the gaze of the driver has been directed to the display region of this display device for at least the extended gazing duration.

Abstract: An electrophoretic display comprising a fluid including a first species of particles and a charge control agent disposed between first and second electrodes. When a first addressing impulse have an electrical polarity is applied to the medium, the first species of particles move in one direction relative to the electric field, but when a second addressing impulse, larger than the first addressing impulse but having the same electrical polarity, is applied to the medium, the first species of particles move in the opposed direction relative to the electric field.

Abstract: Disclosed is a display device for use of a surface display of an arbitrary shape, including a plural number of display element units, each made up of a circuit that forms a single stage of a scanning circuit and a pixel circuit connected to an output of the scanning circuit, are arranged in a unicursal fashion on a display substrate.
