Abstract: The present invention is a method for measuring touching position, touching energy and display device thereof. While touching position is measured, at least two sensors are installed in dispersing form under the sensing panel of touch control equipment. The sensing panel is divided into a plurality of grids.

While touching energy is measured, at least one sensor is installed under the sensing panel. The sensing panel is divided into a plurality of grids. Touching position would be obtained by the above method for measuring touching position or other methods. The touching energy could be calculated by comparing the detected touching signal energy with energy of benchmark signal at touching position in corresponding grid.

Abstract: To provide a semiconductor device including a small-area circuit with high withstand voltage, an oxide semiconductor (OS) transistor is used as some of transistors included in a circuit handling an analog signal in a circuit to which high voltage is applied. The use of an OS transistor with high withstand voltage as a transistor requiring resistance to high voltage enables the circuit area to be reduced without lowering the performance, as compared to the case using a Si transistor. Furthermore, an OS transistor can be provided over a Si transistor, so that transistors using different semiconductor layers can be stacked, resulting in a much smaller circuit area.

Accordingly, a sense of incongruity due to discontinuity of a displayed image by frame parts can be reduced and a lack of display information can be prevented.
Abstract: A touch-sensitive surface for a computer animator to create or modify a computer-generated image includes processes for differentiating between click and drag operations. The included processes also beneficially reduce input errors. When a touch object (e.g., finger or stylus) touches the drawing table, information regarding the duration of the touch and the movement of the touch are used to determine whether the touch input represents a (graphical user interface) click or a drag operation.
Abstract: A signal processing circuit is provided, which is suitable to be connected to a signal receiving conductor of a capacitive position detecting sensor, which has low power consumption and small circuit scale, and which allows setting of a small value as the capacitance value of a capacitor used for I-V conversion. After a receiving conductor is clamped to a predetermined potential by a clamp circuit, this receiving conductor clamped to the predetermined potential is connected to a capacitor circuit via a gate circuit. Thereby, a potential that changes corresponding to a position indicated by an indicator such as a finger is generated in the capacitor circuit, and a voltage signal generated in this capacitor circuit is converted to a digital signal to be output.

In response to detecting a predetermined pressure change of a single contact on the trackpad, the single contact is ignored. After detecting a new contact on the trackpad after a predetermined period of time without any contact on the trackpad, any movement tied to a predetermined amount of increasing pressure on the trackpad for the new contact is temporarily discarded, for a preset amount of time.
