Abstract: A touch detection module includes driving electrodes extending parallel to each other, sensing electrodes crossing the driving electrodes, and a touch driver circuit for supplying touch driving signals to the driving electrodes and for detecting touch sensing signals through the sensing electrodes to determine touch position coordinates. The touch driver circuit selects between a group driving scheme and a sequential driving scheme for at least one frame. According to the group driving scheme, the touch driver circuit sorts the driving electrodes into groups, simultaneously drives driving electrodes in a same group among the groups, and drives the groups at different times. According to the sequential driving scheme, the touch driving circuit sequentially drives the driving electrodes.

Abstract: A touch sensor includes first touch cells disposed in a first touch sensing area, the first touch cells each including a first touch pattern and a first dummy pattern, and second touch cells disposed in a second touch sensing area, the second touch cells each including a second touch pattern and a second dummy pattern. An area of a first dummy pattern area in which the first dummy pattern is disposed is greater than an area of a second dummy pattern area in which the second dummy pattern is disposed.

Abstract: The present disclosure relates to an apparatus for fabricating a display panel including: an attachment member having a fixing portion in a pressurization direction to which a pressurization header is fixed, an attachment driving member configured to move the attachment member and the pressurization header in the pressurization direction or a detachment direction through a fixing frame of the attachment member, a first pressure sensing module between the pressurization header and the attachment member and configured to generate first pressure detection signals according to pressure applied to the pressurization header, a gradient setting module configured to set a gradient of the pressurization header based on magnitudes of the first pressure detection signals, and a gradient control module configured to adjust gradients of the pressurization header, the attachment member, and the fixing frame according to control of the gradient setting module.

Abstract: A method for making a silicon wafer includes the steps of generating and stabilizing embryos that become oxygen precipitates by succeeding thermal annealing applied during a semiconductor device manufacturing process. In the silicon wafer, embryos are substantially removed in a denuded zone, and embryos are distributed at a relatively higher concentration in a bulk region. Also, by controlling behaviors of embryos, a silicon wafer having a desired concentration profile of oxygen precipitates by succeeding thermal annealing is manufactured with high reliability and reproducibility.
