在產品出廠前，第一顯示面板模組110的顯示參數（以下稱第一顯示參數）可以被設定為第一初始值，而第二顯示面板模組120的顯示參數（以下稱第二顯示參數）可以被設定為第二初始值。當第一顯示參數被設定為第一初始值且第二顯示參數被設定為第二初始值時，第一顯示面板模組110的顯示特性與第二顯示面板模組120的顯示特性可以趨近一致，因此使用者可以體驗較佳的立體視覺效果。因為第一顯示面板模組110的顯示特性與第二顯示面板模組120的顯示特性可以趨近一致，因此第一初始值與第二初始值被視為（被定義為）相互符合。Before the product leaves the factory, the display parameters of the first display panel module 110 (hereinafter referred to as the first display parameter) may be set as the first initial value, and the display parameters of the second display panel module 120 (hereinafter referred to as the second display parameter) ) can be set to the second initial value. When the first display parameter is set to the first initial value and the second display parameter is set to the second initial value, the display characteristic of the first display panel module 110 and the display characteristic of the second display panel module 120 may approach Consistent, so users can experience better stereoscopic effects. Because the display characteristics of the first display panel module 110 and the display characteristics of the second display panel module 120 can be nearly identical, the first initial value and the second initial value are considered (defined as) to coincide with each other.
在理想狀況下，第一初始值可能等於第二初始值。在一些實施環境下，第一初始值可能接近但不等於第二初始值。無論如何，縱使第一初始值與第二初始值存在著差值，但只要具有第一初始值的第一顯示面板模組110的顯示特性與具有第二初始值的第二顯示面板模組120的顯示特性二者趨近一致，則第一初始值與第二初始值可以被視為（被定義為）相互符合。反之，若具有第一顯示參數的第一顯示面板模組110的顯示特性與具有第二顯示參數的第二顯示面板模組120的顯示特性二者不一致，則第一顯示參數與第二顯示參數可以被視為（被定義為）相互不符合。Under ideal conditions, the first initial value may be equal to the second initial value. In some implementations, the first initial value may be close to but not equal to the second initial value. In any case, even if there is a difference between the first initial value and the second initial value, as long as the display characteristic of the first display panel module 110 having the first initial value and the second display panel module 120 having the second initial value The display characteristics are both consistent, and the first initial value and the second initial value can be considered (defined as) to coincide with each other. On the other hand, if the display characteristics of the first display panel module 110 having the first display parameter are not consistent with the display characteristics of the second display panel module 120 having the second display parameter, the first display parameter and the second display parameter Can be considered (defined as) non-conformance with each other.
圖2是依照本發明的一實施例的一種多顯示面板裝置的顯示參數調整方法的流程示意圖。請參照圖1與圖2，在步驟S210中，第一顯示面板模組110可以依據第一顯示面板模組110的溫度（亦即溫度感測器111所偵測到的溫度，以下稱第一溫度）來決定是否將第一顯示面板模組110的第一顯示參數由第一初始值動態調整至第一目前值。所述第一目前值相關於（響應於）所述第一溫度。在步驟S220中，第二顯示面板模組120可以依據第二顯示面板模組120的溫度（亦即溫度感測器121所偵測到的溫度，以下稱第二溫度）來決定是否將第二顯示面板模組120的第二顯示參數由第二初始值動態調整至第二目前值。所述第二目前值相關於（響應於）所述第二溫度。FIG. 2 is a schematic flow chart of a method for adjusting display parameters of a multi-display panel device according to an embodiment of the invention. Referring to FIG. 1 and FIG. 2, in step S210, the first display panel module 110 can be based on the temperature of the first display panel module 110 (that is, the temperature detected by the temperature sensor 111, hereinafter referred to as the first The temperature determines whether the first display parameter of the first display panel module 110 is dynamically adjusted from the first initial value to the first current value. The first current value is related to (in response to) the first temperature. In step S220, the second display panel module 120 can determine whether to be the second according to the temperature of the second display panel module 120 (that is, the temperature detected by the temperature sensor 121, hereinafter referred to as the second temperature). The second display parameter of the display panel module 120 is dynamically adjusted from the second initial value to the second current value. The second current value is related to (in response to) the second temperature.
在實際使用情境中，第一顯示面板模組110的溫度（亦即溫度感測器111所偵測到的溫度）可能不同於第二顯示面板模組120的溫度（亦即溫度感測器121所偵測到的溫度）。因此，第一顯示面板模組110的第一顯示參數（第一目前值）與第二顯示面板模組120的第二顯示參數（第二目前值）可能相互不符合。第一目前值（第一顯示參數）與的第二目前值（第二顯示參數）相互不符合，意味著第一顯示面板模組110的顯示特性與第二顯示面板模組120的顯示特性二者不一致。In the actual use scenario, the temperature of the first display panel module 110 (ie, the temperature detected by the temperature sensor 111) may be different from the temperature of the second display panel module 120 (ie, the temperature sensor 121). The detected temperature). Therefore, the first display parameter (the first current value) of the first display panel module 110 and the second display parameter (the second current value) of the second display panel module 120 may not coincide with each other. The first current value (the first display parameter) and the second current value (the second display parameter) do not match each other, which means that the display characteristic of the first display panel module 110 and the display characteristic of the second display panel module 120 are two. Inconsistent.
處理電路130耦接至第一顯示面板模組110與第二顯示面板模組120，以獲知第一顯示參數與第二顯示參數。在步驟S230中，處理電路130可以決定是否進一步調整第一顯示面板模組110的第一顯示參數及/或第二顯示面板模組120的第二顯示參數，以使第一顯示參數與第二顯示參數相互符合。The processing circuit 130 is coupled to the first display panel module 110 and the second display panel module 120 to learn the first display parameter and the second display parameter. In step S230, the processing circuit 130 may determine whether to further adjust the first display parameter of the first display panel module 110 and/or the second display parameter of the second display panel module 120 to make the first display parameter and the second The display parameters match each other.
舉例來說，第一顯示面板模組110可以比較第一顯示面板模組110的第一溫度與第一門檻溫度，而獲得第一比較結果。依據第一比較結果，第一顯示面板模組110可以決定是否調整第一顯示參數。第二顯示面板模組120可以比較第二顯示面板模組120的第二溫度與第二門檻溫度，而獲得第二比較結果。依據第二比較結果，第二顯示面板模組120可以決定是否調整第二顯示參數。所述第一門檻溫度與所述第二門檻溫度可以依照設計需求來決定。在一些實施例中（但不限於此），所述第一門檻溫度可以等於所述第二門檻溫度。依據所述第一比較結果與所述第二比較結果，處理電路130可以知道第一溫度與第二溫度的差異，進而推知第一顯示面板模組110的第一顯示參數與第二顯示面板模組120的第二顯示參數相互不符合。因此在步驟S230中，處理電路130可以進一步調整第一顯示參數及/或第二顯示參數，以使第一顯示參數與第二顯示參數相互符合。For example, the first display panel module 110 can compare the first temperature of the first display panel module 110 with the first threshold temperature to obtain a first comparison result. According to the first comparison result, the first display panel module 110 can determine whether to adjust the first display parameter. The second display panel module 120 can compare the second temperature of the second display panel module 120 with the second threshold temperature to obtain a second comparison result. According to the second comparison result, the second display panel module 120 can determine whether to adjust the second display parameter. The first threshold temperature and the second threshold temperature may be determined according to design requirements. In some embodiments, but not limited thereto, the first threshold temperature may be equal to the second threshold temperature. According to the first comparison result and the second comparison result, the processing circuit 130 can know the difference between the first temperature and the second temperature, and further infer the first display parameter of the first display panel module 110 and the second display panel module. The second display parameters of group 120 do not match each other. Therefore, in step S230, the processing circuit 130 may further adjust the first display parameter and/or the second display parameter to make the first display parameter and the second display parameter coincide with each other.
在另一些實施例中，第一過溫事件可以被定義為「第一顯示面板模組110的第一溫度大於所述第一門檻溫度」，而第二過溫事件被定義為「第二顯示面板模組120的第二溫度大於所述第二門檻溫度」。依據所述第一過溫事件及/或所述第二過溫事件，處理電路130在步驟S230中可以決定是否進一步調整第一顯示面板模組110的第一顯示參數及/或第二顯示面板模組120的第二顯示參數，以使第一顯示參數與第二顯示參數相互符合。In other embodiments, the first over temperature event may be defined as “the first temperature of the first display panel module 110 is greater than the first threshold temperature”, and the second over temperature event is defined as “the second display” The second temperature of the panel module 120 is greater than the second threshold temperature. According to the first over temperature event and/or the second over temperature event, the processing circuit 130 may determine whether to further adjust the first display parameter of the first display panel module 110 and/or the second display panel in step S230. The second display parameter of the module 120 is such that the first display parameter and the second display parameter conform to each other.
圖3是依照本發明的一實施例說明圖2所示顯示參數調整方法的詳細流程示意圖。請參照圖1與圖3。圖3所示步驟S210包括步驟S211、步驟S212與步驟S213，而步驟S220包括步驟S221、步驟S222與步驟S223。在初始化期間，第一顯示面板模組110的第一顯示參數可以被設定為所述第一初始值（步驟S211），而第二顯示面板模組120的第二顯示參數可以被設定為所述第二初始值（步驟S221）。完成初始化期間後，溫度感測器111可以偵測第一顯示面板模組110的溫度（步驟S212），而溫度感測器121可以偵測第二顯示面板模組120的溫度（步驟S222）。FIG. 3 is a detailed flow chart illustrating the method for adjusting display parameters shown in FIG. 2 according to an embodiment of the invention. Please refer to FIG. 1 and FIG. 3. Step S210 shown in FIG. 3 includes step S211, step S212, and step S213, and step S220 includes step S221, step S222, and step S223. During initialization, the first display parameter of the first display panel module 110 may be set to the first initial value (step S211), and the second display parameter of the second display panel module 120 may be set to the The second initial value (step S221). After the initialization period is completed, the temperature sensor 111 can detect the temperature of the first display panel module 110 (step S212), and the temperature sensor 121 can detect the temperature of the second display panel module 120 (step S222).
當步驟S212的判斷結果表示發生了第一過溫事件（亦即，第一顯示面板模組110的第一溫度大於所述第一門檻溫度）時，第一顯示面板模組110可以將第一顯示面板模組110的第一顯示參數由第一初始值動態調整至第一目前值（步驟S213）。步驟S213的實施方式可以是習知的動態調整演算法或是其他演算法，故不再贅述。當步驟S222的判斷結果表示發生了第二過溫事件（亦即，第二顯示面板模組120的第二溫度大於所述第二門檻溫度）時，第二顯示面板模組120可以將第二顯示面板模組120的第二顯示參數由第二初始值動態調整至第二目前值（步驟S223）。步驟S223的實施方式可以是習知的動態調整演算法或是其他演算法，故不再贅述。When the result of the determination in step S212 indicates that the first over temperature event occurs (that is, the first temperature of the first display panel module 110 is greater than the first threshold temperature), the first display panel module 110 may be the first The first display parameter of the display panel module 110 is dynamically adjusted from the first initial value to the first current value (step S213). The implementation of step S213 may be a conventional dynamic adjustment algorithm or other algorithms, and therefore will not be described again. When the result of the determination in step S222 indicates that the second over temperature event occurs (that is, the second temperature of the second display panel module 120 is greater than the second threshold temperature), the second display panel module 120 may be the second The second display parameter of the display panel module 120 is dynamically adjusted from the second initial value to the second current value (step S223). The implementation of step S223 may be a conventional dynamic adjustment algorithm or other algorithms, and therefore will not be described again.
圖3所示步驟S2130包括步驟S231、步驟S232、步驟S233、步驟S234與步驟S235。在步驟S231中，處理電路130可以判斷第一顯示面板模組110是否發生第一過溫事件，與/或判斷第二顯示面板模組120是否發生第二過溫事件。Step S2130 shown in FIG. 3 includes step S231, step S232, step S233, step S234, and step S235. In step S231, the processing circuit 130 may determine whether the first over-temperature event occurs in the first display panel module 110, and/or determine whether the second over-temperature event occurs in the second display panel module 120.
當步驟S231的判斷結果表示所述第一過溫事件與所述第二過溫事件均未發生時，處理電路130可以將第一顯示面板模組110的第一顯示參數維持於所述第一初始值，以及將第二顯示面板模組120的第二顯示參數維持於所述第二初始值（步驟S232）。由於第一初始值與第二初始值相互符合，因此第一顯示面板模組110的顯示特性與第二顯示面板模組120的顯示特性可以趨近一致。When the result of the determination in step S231 indicates that neither the first over-temperature event nor the second over-temperature event occurs, the processing circuit 130 may maintain the first display parameter of the first display panel module 110 at the first The initial value, and maintaining the second display parameter of the second display panel module 120 at the second initial value (step S232). Since the first initial value and the second initial value coincide with each other, the display characteristics of the first display panel module 110 and the display characteristics of the second display panel module 120 may be close to each other.
當第一顯示面板模組110發生第一過溫事件，但是第二顯示面板模組120未發生第二過溫事件時，第一顯示面板模組110會將第一顯示參數由所述第一初始值調整至所述第一目前值（步驟S213），但是第二顯示面板模組120不會去動態調整第二顯示參數。因為第二顯示面板模組120沒有動態調整第二顯示參數，因此在處理電路130調整第二顯示參數之前，第二顯示面板模組120的第二顯示參數仍然維持於第二初始值。當步驟S231的判斷結果表示第一顯示面板模組110發生第一過溫事件且第二顯示面板模組120未發生第二過溫事件時，處理電路130可以調整第二顯示面板模組120的第二顯示參數，以使第二顯示參數符合第一顯示面板模組110的第一顯示參數。舉例來說（但不限於此），當第一顯示面板模組110將第一顯示參數由所述第一初始值調整至所述第一目前值，但第二顯示面板模組120沒有動態調整第二顯示參數時，處理電路130可以將第二顯示參數由所述第二初始值調整至所述第一目前值。由於第一顯示參數與第二顯示參數相互符合，因此第一顯示面板模組110的顯示特性與第二顯示面板模組120的顯示特性可以趨近一致。When the first over-temperature event occurs in the first display panel module 110, but the second over-temperature event does not occur in the second display panel module 120, the first display panel module 110 will use the first display parameter by the first The initial value is adjusted to the first current value (step S213), but the second display panel module 120 does not dynamically adjust the second display parameter. Because the second display panel module 120 does not dynamically adjust the second display parameter, the second display parameter of the second display panel module 120 is still maintained at the second initial value before the processing circuit 130 adjusts the second display parameter. When the result of the determination in step S231 indicates that the first over-temperature event occurs in the first display panel module 110 and the second over-temperature event does not occur in the second display panel module 120, the processing circuit 130 can adjust the second display panel module 120. The second display parameter is such that the second display parameter conforms to the first display parameter of the first display panel module 110. For example, but not limited to, when the first display panel module 110 adjusts the first display parameter from the first initial value to the first current value, the second display panel module 120 has no dynamic adjustment. When the second display parameter is displayed, the processing circuit 130 may adjust the second display parameter from the second initial value to the first current value. Since the first display parameter and the second display parameter are mutually consistent, the display characteristics of the first display panel module 110 and the display characteristics of the second display panel module 120 may be similar.
當第一顯示面板模組110未發生第一過溫事件，但是第二顯示面板模組120發生第二過溫事件時，第一顯示面板模組110不會去動態調整所述第一顯示參數，但是第二顯示面板模組120會將第二顯示參數由所述第二初始值調整至所述第二目前值（步驟S223）。因為第一顯示面板模組110沒有動態調整第一顯示參數，因此在處理電路130調整第一顯示參數之前，第一顯示面板模組110的第一顯示參數仍然維持於第一初始值。當步驟S231的判斷結果表示第一顯示面板模組110未發生第一過溫事件，且第二顯示面板模組120發生第二過溫事件時，處理電路130可以調整第一顯示面板模組110的第一顯示參數，以使第一顯示參數符合第二顯示面板模組120的第二顯示參數。舉例來說（但不限於此），當第二顯示面板模組120將第二顯示參數由所述第二初始值調整至所述第二目前值，但第一顯示面板模組110沒有動態調整第一顯示參數時，處理電路130可以將第一顯示參數由所述第一初始值調整至所述第二目前值。由於第一顯示參數與第二顯示參數相互符合，因此第一顯示面板模組110的顯示特性與第二顯示面板模組120的顯示特性可以趨近一致。When the first over-temperature event does not occur in the first display panel module 110, but the second over-temperature event occurs in the second display panel module 120, the first display panel module 110 does not dynamically adjust the first display parameter. However, the second display panel module 120 adjusts the second display parameter from the second initial value to the second current value (step S223). Because the first display panel module 110 does not dynamically adjust the first display parameter, the first display parameter of the first display panel module 110 remains at the first initial value before the processing circuit 130 adjusts the first display parameter. When the result of the determination in step S231 indicates that the first over-temperature event has not occurred in the first display panel module 110, and the second over-temperature event occurs in the second display panel module 120, the processing circuit 130 can adjust the first display panel module 110. The first display parameter is such that the first display parameter conforms to the second display parameter of the second display panel module 120. For example, but not limited to, when the second display panel module 120 adjusts the second display parameter from the second initial value to the second current value, the first display panel module 110 is not dynamically adjusted. When the parameter is first displayed, the processing circuit 130 may adjust the first display parameter from the first initial value to the second current value. Since the first display parameter and the second display parameter are mutually consistent, the display characteristics of the first display panel module 110 and the display characteristics of the second display panel module 120 may be similar.
當第一顯示面板模組110發生第一過溫事件，而且第二顯示面板模組120發生第二過溫事件時，第一顯示面板模組110會去動態調整所述第一顯示參數（步驟S213），而且第二顯示面板模組120會去動態調整第二顯示參數（步驟S223）。當步驟S231的判斷結果表示第一過溫事件與第二過溫事件均發生時，處理電路130可以將第一顯示面板模組110的第一顯示參數調回至所述第一初始值，以及處理電路130可以將第二顯示面板模組120的第二顯示參數調回至所述第二初始值。由於第一初始值與第二初始值相互符合，因此第一顯示面板模組110的顯示特性與第二顯示面板模組120的顯示特性可以趨近一致。When the first over-temperature event occurs in the first display panel module 110, and the second over-temperature event occurs in the second display panel module 120, the first display panel module 110 dynamically adjusts the first display parameter (step S213), and the second display panel module 120 dynamically adjusts the second display parameter (step S223). When the determination result of step S231 indicates that both the first over-temperature event and the second over-temperature event occur, the processing circuit 130 may adjust the first display parameter of the first display panel module 110 to the first initial value, and The processing circuit 130 can adjust the second display parameter of the second display panel module 120 to the second initial value. Since the first initial value and the second initial value coincide with each other, the display characteristics of the first display panel module 110 and the display characteristics of the second display panel module 120 may be close to each other.
值得注意的是，在不同的應用情境中，第一顯示面板模組110、第二顯示面板模組120及/或處理電路130的相關功能可以利用一般的編程語言（programming languages，例如C或C++）、硬體描述語言（hardware description languages，例如Verilog HDL或VHDL）或其他合適的編程語言來實現為軟體、韌體或硬體。可執行所述相關功能的編程語言可以被佈置為任何已知的計算機可存取媒體（computer-accessible medias），例如磁帶（magnetic tapes）、半導體（semiconductors）記憶體、磁盤（magnetic disks）或光盤（compact disks，例如CD-ROM或DVD-ROM），或者可通過互聯網（Internet）、有線通信（wired communication）、無線通信（wireless communication）或其它通信介質傳送所述編程語言。所述編程語言可以被存放在計算機的可存取媒體中，以便於由計算機的處理器來存取/執行所述編程語言的編程碼（programming codes）。另外，本發明的裝置和方法可以通過硬體和軟體的組合來實現。It should be noted that, in different application scenarios, related functions of the first display panel module 110, the second display panel module 120, and/or the processing circuit 130 may utilize a general programming language (such as C or C++). ), hardware description languages (such as Verilog HDL or VHDL) or other suitable programming language to implement as software, firmware or hardware.

Each of these display panel modules can dynamically adjust display parameters according to temperature, thereby allowing different display panel modules to provide different image frames.
