摘要： A conductive film is provided on the display unit such that the wiring patterns of the two wiring portions overlap with the pixel array patterns of the display unit. A projected wiring pattern, which is obtained when the wiring patterns of the two wiring portions having three-dimensional shapes are projected onto a plane perpendicular to a point of view, includes a regular wiring pattern which has a mesh shape, or an irregular wiring pattern which has mesh shapes and which is formed by making the regular wiring pattern irregular. An indicator of evaluation of moires, which is caused by interference between a combined wiring pattern formed of the regular wiring pattern and projected pixel array patterns obtained when the pixel array patterns are projected onto the same plane, is equal to or less than an evaluation threshold value.

摘要： A touch display device and a driving circuit (300) are disclosed in which the driving circuit (300) is included in the touch display device. The driving circuit (300) may be capable of reducing a chip size and power consumption by configuring an amplifier disposed in an output terminal of a data voltage to be electrically coupled with a feedback capacitor (Cfb) through a switch, and enabling both display driving and touch sensing to be performed through ON/OFF control of the switch. Further, the accuracy and performance of touch sensing may be improved by adjusting an ON/OFF operation of a switch and the number of amplifiers electrically coupled with the feedback capacitor (Cfb), and a circuit structure for touch driving may be further simplified by generating a load-free driving voltage output in a touch driving period using the amplifiers and a digital-to-analog converter within the driving circuit (300).

摘要： An excitation coil (19) surrounding the periphery of the position detecting area is connected to an oscillating circuit (21), which oscillates at a frequency f 0 , through a drive circuit (20). A CPU (18) supplies control signals to a selecting circuit (12), a sample-and-hold circuit (16), an A/D conversion circuit (17), and the drive circuit (20). Based on the control signal output from the CPU (18), the drive circuit (20) controls the power of the signal output from the excitation coil (19) to ON or OFF. Further, the strength of the excitation signal supplied from the excitation coil (19) is controlled based on information obtained by analyzing a signal received from a position indicator (40), such as the position indicated by the position indicator on the position detecting area and/or a strength of the signal received from the position indicator.

摘要： A conductive film includes a wiring pattern having the following characteristics. For each spectrum in which spectrum peaks obtained by performing two-dimensional Fourier transform on transmittance image data of the entire image has normalized spectrum intensities equal to or greater than a specified value, an angle is set to oscillate by each unit of a specific angle. Intensity differences, each of which is obtained from a maximum value and a minimum value of the normalized spectrum intensity for each angle, are calculated. One or more clusters of bars, which indicate frequencies of a histogram at an average value or more of the intensity difference in a case where the histogram is a histogram of the intensity differences, are isolated from the other cluster. In addition, in a case where a second sample standard deviation indicating a variation of first sample standard deviations, each of which indicates a variation of the normalized spectrum intensities at a single angle, in all angular directions is calculated as a quantitative value of the wiring pattern, the quantitative value is in a specific numerical value range.

摘要： Multi-touch touch-sensing devices and methods are described herein. The touch sensing devices can include multiple sense points, each located at a crossing of a drive line and a sense line. In some embodiments, multiple drive lines may be simultaneously or nearly simultaneously stimulated with drive signals having unique characteristics, such as phase or frequency. A sense signal can occur on each sense line that can be related to the drive signals by an amount of touch present at sense points corresponding to the stimulated drive lines and the sense line. By using processing techniques based on the unique drive signals, an amount of touch corresponding to each sense point can be extracted from the sense signal.; The touch sensing methods and devices can be incorporated into interfaces for a variety of electronic devices such as a desktop, tablet, notebook, and handheld computers, personal digital assistants, media players, and mobile telephones.

摘要： The present disclosure provides an in-cell touch panel and a display device. An entire common electrode layer on an array substrate is divided so as to form a plurality of touch driving sub-electrodes and a plurality of common sub-electrodes spaced apart from each other and arranged alternately. The touch driving sub-electrodes are electrically connected to each other via a touch driving signal line so as to form a touch driving electrode, and the common sub-electrodes are electrically connected to each other via a common electrode signal line to form a common electrode. Touch sensing electrodes are arranged on an opposite substrate and cross the touch driving electrodes. The touch driving electrode is driven in a time-division manner, so as to achieve a touch function and a display function. The touch driving electrode consists of a plurality touch driving sub-electrodes and the common electrode also consists of a plurality of common sub-electrodes, so they have an approximately identical signal transmission load, and at a display stage, the common electrode signal is transmitted in the common electrode at a speed approximately identical to in the touch driving electrode. As a result, it is able to prevent the occurrence of an uneven display image, thereby to improve the image quality.
