Description
本發明係關於觸控屏之觸控偵測方法，尤指一種採用多觸控晶片之觸控偵測方法。The present invention relates to a touch detection method for a touch screen, and more particularly to a touch detection method using a multi-touch chip.
觸控屏已廣見於各種電子設備。一般的觸控屏是以一觸控晶片支援其觸控感測器陣列，而大尺寸的觸控屏則需配置多個觸控晶片。Touch screens are widely used in various electronic devices. A general touch screen uses a touch chip to support its touch sensor array, while a large-sized touch screen needs to be equipped with multiple touch chips.
當觸控屏搭配由一主晶片及一從晶片組成之二觸控晶片時，亦即各觸控晶片各負責一半的觸控屏時，一般的觸控偵測方法是直接將從晶片中的各通道資料傳輸給主晶片，再由主晶片的微控制器統一計算整個觸控屏的觸摸位置。When the touch screen is equipped with two touch chips consisting of a master chip and a slave chip, that is, each touch chip is responsible for half of the touch screen, the general touch detection method is to directly transmit the channel data in the slave chip to the master chip, and then the microcontroller of the master chip uniformly calculates the touch position of the entire touch screen.
然而，此作法需要在每顆晶片都配置足夠大的暫存記憶空間來存放整個觸控屏的感測資料，導致晶片面積和成本增加，且傳輸從晶片通道資料到主晶片會增加額外的時間而降低觸控反應速度。However, this approach requires that each chip be equipped with a sufficient temporary memory space to store the sensing data of the entire touch screen, which increases the chip area and cost. In addition, the transmission of chip channel data from the main chip will increase the extra time and reduce the touch response speed.
為解決上述的問題，本領域亟需一種新穎的多觸控晶片聯合偵測方法。In order to solve the above problems, a novel multi-touch chip joint detection method is urgently needed in the art.

本發明之另一目的在於揭露一種多觸控晶片聯合偵測方法，其可在一手指觸摸操作發生在兩個觸控晶片所對應之兩個子陣列的鄰接區域時，獲得該手指觸摸操作之較完整的觸摸感測分布，從而能夠在該鄰接區域提供精確的觸摸點座標。Another object of the present invention is to disclose a multi-touch chip joint detection method, which can obtain a more complete touch sensing distribution of a finger touch operation when a finger touch operation occurs in adjacent areas of two sub-arrays corresponding to two touch chips, thereby providing accurate touch point coordinates in the adjacent area.
本發明之另一目的在於揭露一種觸控模組，其可藉由前述之方法極小化觸控晶片的暫存記憶空間、優化觸控屏的整體觸控反應速度及在兩個子陣列的鄰接區域提供精確的觸摸點座標。Another object of the present invention is to disclose a touch module which can minimize the temporary storage space of the touch chip, optimize the overall touch response speed of the touch screen, and provide accurate touch point coordinates in the adjacent area of two sub-arrays through the aforementioned method.

本發明之原理在於：The principle of the present invention is:
(一)將一觸控屏之觸控感測陣列分成相鄰之一第一半陣列和一第二半陣列，並使一主晶片負責掃描該第一半陣列及使一從晶片負責掃描該第二半陣列；(1) dividing a touch sensing array of a touch screen into a first half array and a second half array adjacent to each other, and making a master chip responsible for scanning the first half array and making a slave chip responsible for scanning the second half array;
(二)將該第一半陣列中與該第二半陣列相鄰之部分列定義為第一相鄰區，將該第二半陣列中與該第一半陣列相鄰之部分列定義為第二相鄰區；(ii) defining a portion of the rows in the first half array that are adjacent to the second half array as a first adjacent region, and defining a portion of the rows in the second half array that are adjacent to the first half array as a second adjacent region;
(三)該主晶片掃描該第一半陣列以獲得一第一幀感測數據並將該第一幀感測數據中與該第一相鄰區對應的第一邊界感測數據傳送至該從晶片，且該從晶片掃描該第二半陣列以獲得一第二幀感測數據並將該第二幀感測數據中與該第二相鄰區對應的第二邊界感測數據傳送至該主晶片；以及(iii) the master chip scans the first half array to obtain a first frame of sensing data and transmits first boundary sensing data corresponding to the first adjacent region in the first frame of sensing data to the slave chip, and the slave chip scans the second half array to obtain a second frame of sensing data and transmits second boundary sensing data corresponding to the second adjacent region in the second frame of sensing data to the master chip; and
(四)該主晶片將該第一幀感測數據和該第二邊界感測數據併成一幀第一等效感測數據，並依一閾值對該幀第一等效感測數據進行一觸摸判斷處理以產生第一組觸摸位置數據，及將該第一組觸摸位置數據傳送至一應用處理器；且該從晶片將該第二幀感測數據和該第一邊界感測數據併成一幀第二等效感測數據，並依該閾值對該幀第二等效感測數據進行該觸摸判斷處理以產生第二組觸摸位置數據，及將該第二組觸摸位置數據傳送至該應用處理器。(iv) the master chip combines the first frame of sensing data and the second boundary sensing data into a frame of first equivalent sensing data, performs a touch judgment processing on the frame of first equivalent sensing data according to a threshold value to generate a first set of touch position data, and transmits the first set of touch position data to an application processor; and the slave chip combines the second frame of sensing data and the first boundary sensing data into a frame of second equivalent sensing data, performs the touch judgment processing on the frame of second equivalent sensing data according to the threshold value to generate a second set of touch position data, and transmits the second set of touch position data to the application processor.
另外，較佳地，該第一組觸摸位置數據和該第二組觸摸位置數據代表各觸摸點在觸控感測陣列中的絕對位置，亦即，該主晶片和該從晶片在計算有效觸摸點的座標時已將該幀第一等效感測數據和該幀第二等效感測數據在該觸控感測陣列中的對應位置納入考慮。In addition, preferably, the first set of touch position data and the second set of touch position data represent the absolute position of each touch point in the touch sensing array, that is, the master chip and the slave chip have taken into account the corresponding positions of the frame of first equivalent sensing data and the frame of second equivalent sensing data in the touch sensing array when calculating the coordinates of the effective touch point.

In addition, it is worth mentioning that when a finger touch operation occurs in the middle of the first half array and the second half array, the present invention can obtain a more complete touch sensing distribution of the finger touch operation from the first equivalent sensing data of the frame of the main chip, and/or obtain a more complete touch sensing distribution of the finger touch operation from the second equivalent sensing data of the frame of the slave chip, thereby providing accurate touch point coordinates in the middle of the first half array and the second half array.
