一實施例中顯示面板102的驅動方法可參照第3圖及第4圖的訊號時序示意圖了解，其中第3圖為次顯示畫素相關的驅動時序波形，第4圖為指紋辨識模式期間，指紋感測單元208相關的驅動時序波形。 In one embodiment, the driving method of the display panel 102 can be understood by referring to the signal timing diagrams of FIG. 3 and FIG. 4, where FIG. 3 is the driving timing waveform related to the sub-display pixels, and FIG. 4 is the fingerprint during the fingerprint recognition mode. The driving timing waveform related to the sensing unit 208.

請參照第3圖，顯示面板102的驅動方法包括提供顯示掃描訊號至顯示掃描線Gp以驅動顯示掃描線Gp(例如第3圖顯示提供至顯示掃描線Gp_n、顯示掃描線Gp_n+1的顯示掃描訊號)，並提供顯示資料訊號至顯示資料線S(例如第3圖顯示提供至第一顯示資料線Sn+1、第三顯示資料線Sn的顯示資料訊號)，從而驅動次顯示畫素並控制次顯示畫素的亮、暗態。當顯示開關電晶體Tp為開啟狀態(即閘極下方的通道極性相同於源/汲極)時，顯示資料訊號可寫入次顯示畫素。一實施例中，顯示資料訊號可包括第一顯示資料訊號及第二顯示資料訊號。第一顯示資料訊號可為提供至電性連接白色次畫素W及綠色次畫素G之第一群組顯示資料線SP1的資料顯示訊號，例如第3圖中顯示提供至第一顯示資料線Sn+1的顯示資料訊號。第二顯示資料訊號可為提供至電性連接紅色次畫素R及藍色次畫素B之第二群組顯示資料線SP2的資料顯示訊號，例如第3圖中顯示提供至第三顯示資料線Sn的顯示資料訊號。實施例中，可控制顯示掃描訊號及顯示資料訊號，以在顯示模式期間(即顯示影像模式及/或非指紋感測/辨識的觸控感應期間)利用次顯示畫素顯示影像，並在指紋辨識模式期間控制次顯示畫素的亮、暗態，從而顯示影像。一實施例中，顯示模式期間，感測開關電晶體Tw是維持在關閉的狀態，顯示面板102不會執行指紋感測作用。一實施例中，在指紋辨識模式及顯示模式期間，可在畫面週期(frame)期間利用顯示掃描訊號逐一驅動顯示掃描線Gp。在顯示模式期間，第一顯示資料訊號及第二顯示資料訊號可維持在一亮態電壓(例如白畫面灰階訊號)。在指紋辨識模式期間，第一顯示資料訊號可具有一脈波頻率，第一顯示資料訊號的脈波頻率可大於顯示掃描訊號的顯示掃描頻率(Fd)，且第二顯示資料訊號可維持在一暗態電壓(例如黑畫面灰階訊號)，從而只驅動白色次畫素W及綠色次畫素G其中至少一者為亮態，例如，只驅動白色次畫素W為亮態(此時紅色次畫素R、綠色次畫素G、及藍色次畫素B為暗態)，且顯示亮度可隨之而變；或者，只驅動綠色次畫素G為亮態(此時白色次畫素W、紅色次畫素R、及藍色次畫素B為暗態)。 Referring to FIG. 3, the driving method of the display panel 102 includes providing a display scan signal to the display scan line Gp to drive the display scan line Gp (for example, FIG. 3 shows the display scan provided to the display scan line Gp_n and the display scan line Gp_n+1 Signal), and provide the display data signal to the display data line S (for example, the display data signal provided by the first display data line Sn+1 and the third display data line Sn in the third display) to drive the secondary display pixels and control The light and dark states of the pixels are displayed. When the display switch transistor Tp is turned on (that is, the channel under the gate has the same polarity as the source/drain), the display data signal can be written to the secondary display pixel. In one embodiment, the display data signal may include a first display data signal and a second display data signal. The first display data signal may be a data display signal provided to the first group display data line SP1 electrically connecting the white sub-pixel W and the green sub-pixel G, for example, the display in FIG. 3 is provided to the first display data line Sn+1 display data signal. The second display data signal may be a data display signal provided to the second group display data line SP2 electrically connected to the red sub-pixel R and the blue sub-pixel B, for example, the display in FIG. 3 provides the third display data Display data signal of line Sn. In an embodiment, the display scan signal and the display data signal can be controlled to display the image using the sub-display pixels during the display mode (ie, during the display image mode and/or during non-fingerprint sensing/recognition touch sensing), and the fingerprint During the recognition mode, the light and dark states of the sub-display pixels are controlled to display images. In one embodiment, during the display mode, the sensing switch transistor Tw is maintained in a closed state, and The display panel 102 does not perform fingerprint sensing. In one embodiment, during the fingerprint recognition mode and the display mode, the display scan lines Gp may be driven one by one using the display scan signal during the frame period. During the display mode, the first display data signal and the second display data signal can be maintained at a bright state voltage (such as a white screen gray-scale signal). During the fingerprint identification mode, the first display data signal may have a pulse frequency, the pulse frequency of the first display data signal may be greater than the display scan frequency (Fd) of the display scan signal, and the second display data signal may be maintained at a Dark state voltage (for example, black grayscale signal), so that only one of the white sub-pixel W and the green sub-pixel G is in the bright state, for example, only the white sub-pixel W is in the bright state (in this case, red The sub-pixel R, the green sub-pixel G, and the blue sub-pixel B are in a dark state), and the display brightness can be changed accordingly; or, only the green sub-pixel G is driven in a bright state (the white sub-picture (Pixel W, red sub-pixel R, and blue sub-pixel B are in a dark state).

請參照第4圖，一實施例中，可利用第4圖的波形時序在指紋辨識模式期間驅動白色次畫素W為亮態，即白色次畫素W的液晶傾倒方位允許光線穿過其中，因此來自背光源的光線可穿過白色次畫素W的液晶層，然後經指紋反射至白色次畫素W的指紋感測單元208中。在白色次畫素W為亮態期間進行感測指紋辨識可得到優異的指紋辨識品質。亦可透過亮態的白色次畫素W調控指紋辨識期間顯示畫面的亮度。 Please refer to FIG. 4. In one embodiment, the waveform timing of FIG. 4 can be used to drive the white sub-pixel W to be in a bright state during the fingerprint recognition mode, that is, the liquid crystal tilting orientation of the white sub-pixel W allows light to pass through it. Therefore, the light from the backlight can pass through the liquid crystal layer of the white sub-pixel W, and then reflected by the fingerprint to the fingerprint sensing unit 208 of the white sub-pixel W. Sensing fingerprint recognition while the white sub-pixel W is in the bright state can obtain excellent fingerprint recognition quality. The brightness of the display screen during fingerprint recognition can also be adjusted through the bright white sub-pixel W.

一實施例中，可利用第5圖的波形時序在指紋辨識模式期間驅動綠色次畫素G為亮態，即綠色次畫素G的液晶傾倒方位允許光線穿過其中，因此來自背光源的光線可穿過綠色次畫素G的液晶層，然後穿過綠色濾光層過濾射出綠光波段的光線，並以綠光波段的光線經指紋反射至白色次畫素W的指紋感測單元208中。此實施例中，由於綠光波段的光線對於人體血液具有較高的吸收率，故可做為個人特徵值辨識，達到防偽效果。 In one embodiment, the waveform timing of FIG. 5 can be used to drive the green sub-pixel G to be in a bright state during the fingerprint recognition mode, that is, the liquid crystal tilting orientation of the green sub-pixel G allows light to pass through it, so the light from the backlight It can pass through the liquid crystal layer of the green sub-pixel G, and then passes through the green filter layer to filter the light emitted from the green light band, and the light of the green light band is reflected by the fingerprint to the fingerprint sensing unit 208 of the white sub-pixel W . In this embodiment, since the light in the green band has a high absorption rate for human blood, it can be used as a personal characteristic value identification to achieve the anti-counterfeiting effect.

顯示面板102的驅動方法包括在指紋辨識模式期間，提供感測掃描訊號至感測掃描線Gs以驅動感測掃描線Gs並進而驅動指紋感測單元208，且讀取從感測訊號輸出線K輸出的指紋感測輸出訊號。每個frame期間利用感測掃描訊號逐一驅動感測掃描線Gs。實施例中，當在感測開關電晶體Tw開啟期間(即積分電路211讀取期間)，積分電路211對指紋感測單元208的節點(例如指紋感測單元208₁的節點N1、指紋感測單元208₂的節點N2)充入參考電位Vref。指紋感測單元208的端點(例如指紋感測單元208₁的端點Q、指紋感測單元208₂的端點Q)具有位準電位Vb。當感測開關電晶體Tw關閉，感測元件207因受手指反射光照射，逐漸漏電至位準電位Vb。參考電位Vref與位準電位Vb電位之間的電位差會隨著感測到的指紋波峰、波谷的反射光強而變。一實施例中，如第4圖所示，經由電性連接感測掃描線Gs_n+1與感測訊號輸出線Kn的指紋感測單元208₁感測到的電位差△V1為節點N1處的參考電位Vref與位準電位Vb之間的電位差，而經由電性連接感測掃描線Gs_n+2 與感測訊號輸出線Kn+1的指紋感測單元208₂感測到的電位差△V2不同於△V1，即△V1>△V2，其中△V1可表示指紋波峰訊號，且△V2可表示指紋波谷訊號。 The driving method of the display panel 102 includes providing a sensing scanning signal to the sensing scanning line Gs during the fingerprint recognition mode to drive the sensing scanning line Gs and thereby the fingerprint sensing unit 208, and reading the output line K from the sensing signal The output fingerprint senses the output signal. During each frame, the sensing scan signals Gs are driven one by one using the sensing scan signals. Embodiment, when the sensing switch is turned on during the transistor Tw (i.e., the integrating circuit 211 during the read), the integrating circuit 211 node fingerprint sensing unit 208 (e.g., a fingerprint sensing unit ₂₀₈₁ of the node N1, fingerprint sensing The node N2 of the unit 208 ₂ is charged with the reference potential Vref. Endpoints 208 (e.g., a fingerprint sensing unit node Q _2081, Q fingerprint sensing unit 208 Endpoint ₂₎ of fingerprint sensing unit having a potential level Vb. When the sensing switch transistor Tw is turned off, the sensing element 207 is gradually leaked to the level potential Vb due to the light reflected by the finger. The potential difference between the reference potential Vref and the level potential Vb potential will vary with the reflected light intensity of the peaks and troughs of the sensed fingerprint. In one embodiment, as Fig. 4, the via is electrically connected to the sensing scan line Gs_n + 1 and the sensing signal output line Kn fingerprint sensing unit ₂₀₈₁ senses the potential difference △ V1 as a reference at node N1 The potential difference between the potential Vref and the level potential Vb, and the potential difference △V2 sensed by the fingerprint sensing unit 208 ₂ electrically connected to the scanning line Gs_n+2 and the sensing signal output line Kn+1 is △V2 different from △ V1, namely △V1>△V2, where △V1 can represent the fingerprint peak signal, and △V2 can represent the fingerprint valley signal.
