在實際操作時,以顯示模組20為液晶顯示模組(LCM)為例,其所顯示的畫面會以60Hz(16.66ms)的頻率更新,也就是時序控制電路43需要以60Hz的頻率產生一個圖框(frame),因此,時序控制電路43會將畫面掃描時間(frame time)分成三個時間週期,第一時間週期T1用於供顯示模組20顯示畫面內容;第二時間週期T2為電磁感應 偵測時間,時序控制電路43會先控制第一閘極驅動器314依序將兩相鄰或兩條特定間距的第一導線1電連接,以形成感應迴路,並控制第一感測電路41發出偵測訊號,以感測一磁性筆(或一具磁通量變化電磁筆,圖未示)的縱向觸壓位置。 In the actual operation, taking the display module 20 as a liquid crystal display module (LCM) as an example, the displayed screen will be updated at a frequency of 60 Hz (16.66 ms), that is, the timing control circuit 43 needs to generate a frequency of 60 Hz. a frame, therefore, the timing control circuit 43 divides the frame time into three time periods, the first time period T1 is used for the display module 20 to display the screen content; the second time period T2 is electromagnetic induction During the detection time, the timing control circuit 43 first controls the first gate driver 314 to electrically connect two adjacent or two specific pitches of the first wires 1 to form an inductive loop, and controls the first sensing circuit 41 to emit The signal is detected to sense the longitudinal touch position of a magnetic pen (or a magnetic flux change electromagnetic pen, not shown).
進一步配合圖9來說明,假設第Xj條的第一導線1與第Xj+2條的第一導線1因對應的第一開關元件313導通而電連接於第一共用線311,使得兩條第一導線1形成一可供偵測訊號之電流流通的感應迴路,此外,第Xj+1條的第一導線1與第Xj+3條的第一導線1也因對應的第一開關元件313導通而電連接於第一共用線311,使得兩條第一導線1形成一可供偵測訊號之電流流通的感應迴路,其中該兩迴路的偵測區域可以有一重疊區(Xj+1到Xj+2),避免感應偵測死角。 Further, with reference to FIG. 9, it is assumed that the first wire 1 of the Xjth strip and the first wire 1 of the Xj+2 strip are electrically connected to the first common line 311 by the corresponding first switching element 313, so that the two A wire 1 forms an inductive loop for detecting the current flow of the signal. Further, the first wire 1 of the Xj+1 and the first wire 1 of the Xj+3 strip are also turned on by the corresponding first switching element 313. And electrically connected to the first common line 311, so that the two first wires 1 form an inductive loop for detecting the current of the signal, wherein the detection areas of the two loops may have an overlapping area (Xj+1 to Xj+) 2) Avoid inductive detection of dead angles.
當然,也可以是第Xj條、第Xj+1條的兩條第一導線1與第Xk條、第Xk+1條的兩條第一導線1因對應的第一開關元件313導通而電連接於第一共用線311,使得四條第一導線1形成一雙迴路可供偵測訊號之電流流通的感應迴路。 Of course, the two first wires 1 of the Xjth and Xj+1th strips and the two first wires 1 of the Xkth and Xk+1th strips may be electrically connected by the corresponding first switching element 313 being turned on. The first common line 311 is such that the four first wires 1 form a double loop inductive loop for detecting the current flow of the signal.
第一感測電路41則可根據偵測電流通過各該感應迴路所產生的電壓、電流、頻率等訊號變化而判斷電磁筆是否觸壓到該感應迴路,以此來檢測、感應觸控之訊號,以數值運算判斷發生感應變化之位置、距離、觸碰高度和觸碰點強度。因此,第一閘極驅動器314會依一定順序 將兩兩相鄰或兩條特定間距的第一導線1電連接於第一共用線311,使第一感測電路41可以針對所有縱向的第一導線1的訊號進行感測。 The first sensing circuit 41 can detect whether the electromagnetic pen touches the sensing circuit according to the voltage, current, frequency and other signal changes generated by the detecting current through the sensing circuit, thereby detecting and sensing the touch signal. The position, distance, touch height, and touch point intensity at which the induced change occurs are determined by numerical operations. Therefore, the first gate driver 314 will be in a certain order The two first or two adjacent first conductors 1 are electrically connected to the first common line 311, so that the first sensing circuit 41 can sense the signals of all the longitudinal first wires 1.
同樣地,當所有縱向的第一導線1感測結束後,時序控制電路43會改控制第二閘極驅動器324依序將兩相鄰或兩條特定間距的第二導線2電連接,以形成感應迴路,使第二感測電路42可感測所有橫向的第二導線2上的感應訊號,以判斷磁性筆的橫向觸壓位置,如此雙向感測後即可得知電磁筆的觸壓位置等訊號。 Similarly, after all the longitudinal first wires 1 are sensed, the timing control circuit 43 controls the second gate driver 324 to sequentially electrically connect two adjacent or two second wires 2 of a specific pitch to form The sensing circuit enables the second sensing circuit 42 to sense the sensing signals on all the lateral second wires 2 to determine the lateral touch position of the magnetic pen, so that the contact position of the electromagnetic pen can be known after two-way sensing Wait for the signal.
特別說明的是,第一閘極驅動器314(或第二閘極驅動器324)在同一時間內並不僅限於感測一個感應迴路,也可同步感測多數個感應迴路,例如:第Xj條及第Xj+3條所形成之迴路可與第XK條及第XK+1條所形成之迴路同步感測,且感應電路的形成也可以是兩相鄰的或兩相距的第一導線1(或第二導線2),例如:第Xj條及第Xj+1條,或是第XK條及第XK+5條,均不以本實施例為限。 In particular, the first gate driver 314 (or the second gate driver 324) is not limited to sensing one inductive loop at the same time, and can simultaneously sense a plurality of inductive loops, for example, the Xj and the The circuit formed by the Xj+3 strips can be synchronously sensed with the loop formed by the XK and XK+1 strips, and the sensing circuit can also be formed by two adjacent or two spaced first conductors 1 (or The two wires 2), for example, the Xj and Xj+1 bars, or the XK and XK+5 bars, are not limited to this embodiment.
第三時間週期T3為電容感應偵測時間,時序控制電路43會將第一閘極驅動器314及第二閘極驅動器324關閉,即該等第一導線1及第二導線2皆不會相互電連接,第一感測電路41及第二感測電路42係利用第一導線1及第二導線2相互重疊部分的電容和導線間的感應電容,當手指觸控時,因為手指接地而造成電荷、電容重新分布改變,以其所感應發生訊號變化,進行檢測所發生之電荷量、電容感應、或電壓、電流訊號之變化,而藉以偵測觸 摸位置、相距高度、感應強度、數值等訊號。 The third time period T3 is the capacitance sensing detection time, and the timing control circuit 43 turns off the first gate driver 314 and the second gate driver 324, that is, the first wire 1 and the second wire 2 are not electrically connected to each other. The first sensing circuit 41 and the second sensing circuit 42 are connected to each other by using a capacitance between the first wire 1 and the second wire 2 and a sensing capacitance between the wires. When the finger is touched, the charge is caused by the grounding of the finger. The capacitance redistribution changes, and the detected signal changes occur to detect the amount of charge generated, the capacitance sensing, or the voltage and current signals, thereby detecting the touch. Touch the position, height, inductance, value and other signals.

A liquid crystal layer 205, a pixel layer 206, a second substrate 207, and a second polarizer 208. In the embodiment, the first wire 1 and the second wire 2 of the touch sensing module 10 are disposed between the second substrate 207 and the second polarizer 208 to prevent capacitive sensing of the touch sensing module 10 . The effect is affected by the shielding effect of the common electrode layer 204. However, the arrangement positions of the first wire 1 and the second wire 2 are not limited to the embodiment, and may be disposed between the first substrate 202 and the second substrate 207. That is, the first wire 1 and the second wire 2 can be respectively disposed between two adjacent layers between the second polarizer 208 and the first substrate 202.
因此,本實施例之第一導線1及第二導線2相互交錯排列的感應線路,透過開關單元3中第一開關元件313及第二開關元件323的切換(即導通或不導通),感測單元4可刺激、感應、偵測出以電磁筆或磁性元件筆輸入的電磁感應(electromagnetic sensing)觸控及以手指觸控的電容感應(capacitance sensing)觸控的感應訊號的數值、大小(或相對大小)、峰值差異或平均值等相關數據,以達到本發明兼具電容感應式觸控功能和電磁感應式觸控功能之目的,再加上觸控感應模組10佈設於顯示模組20中,更可以減少顯示器100的整體厚度,減少製作成本。 Therefore, the sensing line in which the first wire 1 and the second wire 2 are alternately arranged in the embodiment is switched through the switching (ie, conducting or non-conducting) of the first switching element 313 and the second switching element 323 in the switching unit 3, and sensing The unit 4 can stimulate, sense, and detect the value and size of the electromagnetic sensing touch input by the electromagnetic pen or the magnetic component pen and the sensing signal touched by the finger touch capacitance sensing (or The related data of the relative size, the peak difference, or the average value, in order to achieve the purpose of the capacitive sensing touch function and the electromagnetic induction touch function of the present invention, and the touch sensing module 10 is disposed on the display module 20 In addition, the overall thickness of the display 100 can be reduced, and the manufacturing cost can be reduced.
特別說明的是,顯示模組20可為穿透式、反射 式或是部分穿透部分反射式的顯示器面板,若為反射式顯示器面板,則本實施例之顯示器100將不需要背光源30,以及不需要第一偏光片201,顯示模組20可利用外部光線(例如:陽光)當成光源使用。 In particular, the display module 20 can be transmissive and reflective.
