In other words, the first display area 111 and the third display area 114 in the unit area have more light sensing units 216 and light sensing units 226. In contrast, the density of the pixel PX per unit area in the first display area 111 and the third display area 114 is smaller than the density of the pixel PX per unit area in the first display area 112. However, because the first display area 111 and the third display area 114 correspond to the display area of the curved surface, and the first display area 111 and the third display area 114 are located on both sides of the display device 100 and are located above the display position of the curved surface, The reduction in pixel PX density is relatively small for the visual impact of use.

除此之外，請參考圖6，圖6係為本發明實施例指紋感測操作示意圖。在操作上，由於本發明實施例的顯示裝置100兩側都可以具有指紋(可包含掌紋)的感測功能，因此，控制電路300電性耦接第一指紋感測模組210與第二指紋感測模組220，可用以根據第一指紋感測模組210提供的信號S1以及該第二指紋感測模組220感測的信號S2產生進行使用者身分的認證或識別。詳言之，第一指紋感測模組210提供的信號S1係對應於使用者握持顯示裝置100時，接觸於第一指紋感測模組210的手指或者手掌部分的指紋611的紋理而產生的訊號(例如為對應於指紋611紋理造成的電容大小的變化訊號，或者是對應於指紋611紋理而產生的影像變化信號)。而第二指紋感測模組220提供的信號S2係對應於使用者握持顯示裝置100時，接觸於第二指紋感測模組220的手指或者手掌部分的指紋621、622的紋理而產生的訊號(例如為對應於指紋621、622的紋理造成的電容大小的變化訊號，或者是對應於指紋621、622的紋理而產生的影像變化信號)。而這兩信號S1及信號S2將會被同時用以進行使用者身分的認證或識別。舉例而言，顯示裝置100可以針對信號S1與內存的使用者生物特徵資訊(例如指紋/掌紋紋理資訊進行比對)，如果因為感測資訊不完整、或感測面積過小等因素導致無法進行正確認證，則再輔以信號S2與內存的使用者生物特徵進行比對，進而決定是否將顯示裝置100由鎖定狀態進行解鎖操作、或者是將鎖定的操作/存取權限進行解鎖。或者是顯示裝置100可以要求信號S1及信號S2與顯示裝置100內存的生物特徵資訊進行比對，當兩者進行比對後階符合認證要求，再執行將顯示裝置100由鎖定狀態進行解鎖操作、或者是將鎖定的操作/存取權限進行解鎖。藉此，顯示裝置100可以解決因為指紋偵測設置於邊緣而造成的使用者指紋/掌紋觸碰面積過小的問題，因為兩側的第一指紋感測模組210與指紋感測模組220均可以提供一定面積的指紋感測結果。除此之外，此結構與操作下，也可以提供更嚴謹或者錯誤率更低的身分識別效果，因在部分實施例中，使用者必須兩側的第一指紋感測模組210與指紋感測模組220都提供對應且正確的指紋/掌紋以解鎖顯示裝置100的存取限制，因此，能夠提高破解的難度。In addition, please refer to FIG. 6, which is a schematic diagram of a fingerprint sensing operation according to an embodiment of the present invention. In operation, the display device 100 of the embodiment of the present invention may have a sensing function of a fingerprint (including a palm print) on both sides of the display device 100. Therefore, the control circuit 300 is electrically coupled to the first fingerprint sensing module 210 and the second fingerprint. The sensing module 220 can be used to generate authentication or identification of the user identity according to the signal S1 provided by the first fingerprint sensing module 210 and the signal S2 sensed by the second fingerprint sensing module 220. In detail, the signal S1 provided by the first fingerprint sensing module 210 corresponds to the texture of the fingerprint 611 contacting the finger or the palm portion of the first fingerprint sensing module 210 when the user holds the display device 100. The signal (for example, a change signal corresponding to the size of the capacitance caused by the fingerprint 611 texture, or an image change signal corresponding to the texture of the fingerprint 611). The signal S2 provided by the second fingerprint sensing module 220 is generated corresponding to the texture of the fingerprints 621 and 622 of the finger or palm portion of the second fingerprint sensing module 220 when the user holds the display device 100. The signal (for example, a change signal of the magnitude of the capacitance caused by the texture corresponding to the fingerprints 621, 622, or an image change signal corresponding to the texture of the fingerprints 621, 622). The two signals S1 and S2 will be used for authentication or identification of the user identity at the same time. For example, the display device 100 can compare the signal S1 with the user biometric information of the memory (eg, fingerprint/palm texture information), and cannot be correctly performed because the sensing information is incomplete or the sensing area is too small. The authentication is additionally performed by comparing the signal S2 with the user biometrics of the memory, and further determining whether to unlock the display device 100 from the locked state or unlocking the locked operation/access authority. Alternatively, the display device 100 may require the signal S1 and the signal S2 to be compared with the biometric information stored in the display device 100. When the two meet the authentication requirements, the display device 100 is unlocked by the locked state. Or unlock the locked operation/access rights. Therefore, the display device 100 can solve the problem that the user fingerprint/palm touch area is too small due to the fingerprint detection being disposed on the edge, because the first fingerprint sensing module 210 and the fingerprint sensing module 220 on both sides are both A certain area of fingerprint sensing results can be provided. In addition, this structure and operation can also provide a more rigorous or lower error rate identity recognition effect, because in some embodiments, the user must have the first fingerprint sensing module 210 on both sides and the fingerprint sense. The test module 220 provides corresponding and correct fingerprints/palms to unlock the access restrictions of the display device 100, and thus, the difficulty of cracking can be improved.

更詳細而言，請再參考圖7，步驟S710中，顯示裝置100根據使用者的操作或者其他信號開啟顯示裝置100的顯示區，例如對於顯示面板110進行影像的更新，在某些顯示面板型態中，例如液晶顯示器，則會開啟背光模組(圖未示)，以產生光線。步驟S720中，顯示裝置100會判斷顯示裝置是否處於鎖定狀態(如上所定義)，若顯示裝置100並非處於鎖定狀態，則在步驟S720之後，顯示裝置100會進行觸碰感測的操作S770，詳言之，顯示裝置100可透過第二感測電極230、第一感測電極212以及第三感測電極222來感測使用者的手指位置，其中進行觸控感測操作時的說明如前述的操作，在此不再贅述。步驟S720中，若顯示裝置100處於鎖定狀態，則在步驟S720之後，執行步驟S730，此步驟中，第一指紋感測模組210及第二指紋感測模組220會進行如前述的指紋感測動作(例如透過第一指紋感測模組210及/或第二指紋感測模組220分別取得信號S1及信號S2)。在步驟S740中根據信號S1或信號S2，或者根據信號S1及信號S2所轉譯或者處理後的訊息與內存的使用者特徵進行比對，以決定當前使用者是否具有權限解鎖顯示裝置100。若比對結果符合，則步驟S760會解鎖顯示裝置100、或者是將鎖定的操作/存取權限進行解鎖，並且以步驟S770的操作進行作動。若比對結果不符合，則步驟S750會維持在鎖定的狀態或者持續禁止存取/操作權限，並且再執行S730的指紋偵測操作。透過上述的操作流程，可以有目的性的決定當前第一感測電極212以及第三感測電極222係應該執行指紋感測操作或者是觸控感測操作，避免顯示裝置100進行錯誤或者是冗餘的操作過程。In more detail, please refer to FIG. 7. In step S710, the display device 100 turns on the display area of the display device 100 according to the user's operation or other signals, for example, updating the image on the display panel 110, in some display panel types. In the state, such as a liquid crystal display, a backlight module (not shown) is turned on to generate light. In step S720, the display device 100 determines whether the display device is in the locked state (as defined above). If the display device 100 is not in the locked state, after the step S720, the display device 100 performs the touch sensing operation S770. In other words, the display device 100 can sense the position of the user's finger through the second sensing electrode 230, the first sensing electrode 212, and the third sensing electrode 222, wherein the description of the touch sensing operation is as described above. Operation will not be repeated here. In step S720, if the display device 100 is in the locked state, after step S720, step S730 is performed. In this step, the first fingerprint sensing module 210 and the second fingerprint sensing module 220 perform the fingerprint feeling as described above. The detecting action (for example, obtaining the signal S1 and the signal S2 through the first fingerprint sensing module 210 and/or the second fingerprint sensing module 220 respectively). The message translated or processed according to the signal S1 or the signal S2 or the signal S1 and the signal S2 is compared with the user characteristics of the memory in step S740 to determine whether the current user has the authority to unlock the display device 100. If the comparison result is met, step S760 may unlock the display device 100, or unlock the locked operation/access right, and operate in the operation of step S770. If the comparison result does not match, step S750 is maintained in the locked state or the access/operation authority is continuously prohibited, and the fingerprint detecting operation of S730 is performed again. Through the foregoing operation procedure, the first sensing electrode 212 and the third sensing electrode 222 should be purposely determined to perform a fingerprint sensing operation or a touch sensing operation to prevent the display device 100 from making errors or being redundant. The rest of the operation process.
