TOUCH SIGNAL DETECTION APPARATUS AND TOUCH SIGNAL DETECTION METHOD

摘要

Disclosed herein is a capacitive touch input apparatus of a human finger or a touch input means having conductive characteristics similar thereto, and more particularly, are a touch signal detection apparatus and a touch signal detection method capable of being widely used for a touch detection sensor having different array arrangements. According to the touch signal detection apparatus and the touch signal detection method according to the present invention, one touch signal detection apparatus may be widely used for the touch detection sensor having different arrays by using a re-map technology. According to the touch signal detection apparatus and the touch signal detection method according to the present invention, it is possible to save costs using the same touch signal detection apparatus without producing the separate touch signal detection apparatus for a display device including the touch detection sensor having different arrays.

主权项

1. A touch signal detection apparatus detecting whether a touch is performed at a touch pad including a plurality of touch detection sensors arranged in a matrix form, the touch signal detection apparatus comprising:
a memory unit receiving and storing touch signals through a plurality of touch signal lines connected to the plurality of touch detection sensors of each column to transfer the touch signals generated from the touch detection sensor, a storage array of the memory unit being different from an array of the touch detection sensors; a touch detection unit detecting the touch signals stored in the memory unit to determine whether the touch is performed; a plurality of multiplexers receiving the touch signals through the plurality of touch signal lines connected to the plurality of touch detection sensors of each column to transfer the touch signals generated from the touch detection sensors; and at least one selection signal generator generating a selection signal for selecting some of the touch signals received by each of the multiplexers, wherein a re-map process is performed to match the touch signals stored in the memory unit with the array of the touch detection sensors.
