FIG. 3 is a block diagram of a display device according to an embodiment of the present invention. Referring to FIGS. 1 to 3 , the light source positioning system 100 includes a light source emitter 110 and a display device 120 .

光源發射器110包括微控制器111、控制開關112、雷射二級體113、雷射接收器114、無線通訊模組115以及收音器116。顯示裝置120包括處理器121、顯示面板126、光學觸控模組122、無線通訊模組123、音效晶片124以及揚聲器125。其中，光學觸控模組122整合在顯示面板126中。The light source transmitter 110 includes a microcontroller 111 , a control switch 112 , a laser secondary body 113 , a laser receiver 114 , a wireless communication module 115 and a radio 116 . The display device 120 includes a processor 121 , a display panel 126 , an optical touch module 122 , a wireless communication module 123 , a sound effect chip 124 and a speaker 125 . The optical touch module 122 is integrated in the display panel 126 .

微控制器111是將微型計算機的主要部分集成在一個晶片上的單晶片微型計算機。微型計算機是由大規模集成電路組成的、體積較小的電子計算機。微控制器111耦接至控制開關112、雷射接收器114、無線通訊模組115以及收音器116。控制開關112耦接至雷射二極體113。微控制器111用以切換控制開關112來驅動雷射二極體113開始或停止發送雷射光。The microcontroller 111 is a single-chip microcomputer in which the main parts of the microcomputer are integrated on one wafer. Microcomputers are small electronic computers composed of large-scale integrated circuits. The microcontroller 111 is coupled to the control switch 112 , the laser receiver 114 , the wireless communication module 115 and the radio 116 . The control switch 112 is coupled to the laser diode 113 . The microcontroller 111 is used to switch the control switch 112 to drive the laser diode 113 to start or stop sending laser light.

處理器121例如為中央處理單元（Central Processing Unit，CPU）、物理處理單元（Physics Processing Unit，PPU）、可程式化之微處理器（Microprocessor）、嵌入式控制晶片、數位訊號處理器（Digital Signal Processor，DSP）、特殊應用積體電路（Application Specific Integrated Circuits，ASIC）或其他類似裝置。顯示裝置120中還包括了儲存有多個程式碼片段的儲存裝置（未繪示），而上述程式碼片段在被安裝後，由處理器121來執行，藉此來控制顯示裝置120的輸出。The processor 121 is, for example, a central processing unit (Central Processing Unit, CPU), a physical processing unit (Physics Processing Unit, PPU), a programmable microprocessor (Microprocessor), an embedded control chip, a digital signal processor (Digital Signal Processor) Processor, DSP), Application Specific Integrated Circuits (ASIC), or other similar devices. The display device 120 further includes a storage device (not shown) storing a plurality of code fragments. After the above code fragments are installed, the processor 121 executes them to control the output of the display device 120 .

光學觸控模組122採用光感測器（Photo Sensor）來實現並整合至顯示面板126上，兼顧電容式或光學式觸控的應用，利用光學觸控模組122來偵測光源發射器110的雷射二極體113所發射的雷射光。The optical touch module 122 is realized and integrated on the display panel 126 by a photo sensor, taking into account the application of capacitive or optical touch, and the optical touch module 122 is used to detect the light source emitter 110 the laser light emitted by the laser diode 113 .

無線通訊模組115、123為可雙向傳輸的通訊架構，例如為支援Wi-Fi、全球行動通訊系統（Global System for Mobile Communications，GSM）、第三代行動通訊技術（third-Generation，3G）、***行動通訊技術（fourth-Generation，4G）、第五代行動通訊技術（fifth-Generation，5G）、藍牙（Bluetooth、BLE）等無線通訊協定的晶片或電路。The wireless communication modules 115 and 123 are communication structures capable of bidirectional transmission, such as supporting Wi-Fi, Global System for Mobile Communications (GSM), third-generation mobile communication technology (3G), Chips or circuits of wireless communication protocols such as fourth-generation mobile communication technology (fourth-Generation, 4G), fifth-generation mobile communication technology (fifth-Generation, 5G), Bluetooth (Bluetooth, BLE).

光源發射器110具有測距功能。例如，微控制器111在雷射二極體113向待測距物體（如顯示裝置120）發射雷射光時開始計時，並在雷射接收器114接收到雷射光的反射光時停止計時，並將這段時間轉換為光源發射器110與待測距物體之間的距離。The light source transmitter 110 has a ranging function. For example, the microcontroller 111 starts timing when the laser diode 113 emits laser light to the object to be ranged (such as the display device 120 ), and stops the timing when the laser receiver 114 receives the reflected light of the laser light, and This time is converted into the distance between the light source emitter 110 and the object to be measured.

光源發射器110中設置有激發鍵，在激發鍵被致能時，微控制器111切換控制開關112來驅動雷射二極體113發送雷射光。在光源發射器110被致能發送雷射光之後，微控制器111將計時器的計數時間歸零，並透過計時器來進行時間的計數。接著，微控制器111判斷是否透過無線通訊模組115接收到回應訊號。若未接收到回應訊號，微控制器111進一步判斷經過時間是否大於一指定時間。在此，指定時間可根據雷射光對眼睛的傷害而預先設定。微控制器111會判斷在指定時間內是否透過無線通訊模組115接收到回應訊號。倘若在指定時間內未接收到回應訊號（即，經過時間大於指定時間），微控制器111將控制開關112切換至關閉狀態，使得雷射二極體113停止發射雷射光。另一方面，倘若在指定時間內接收到回應訊號，則持續驅使雷射二極體113發送雷射光。The light source emitter 110 is provided with an excitation key. When the excitation key is enabled, the microcontroller 111 switches the control switch 112 to drive the laser diode 113 to transmit laser light. After the light source emitter 110 is enabled to transmit the laser light, the microcontroller 111 resets the count time of the timer to zero, and counts the time through the timer. Next, the microcontroller 111 determines whether a response signal is received through the wireless communication module 115 . If no response signal is received, the microcontroller 111 further determines whether the elapsed time is greater than a specified time. Here, the specified time may be preset according to the damage to the eyes by the laser light. The microcontroller 111 determines whether a response signal is received through the wireless communication module 115 within a specified time. If no response signal is received within the specified time (ie, the elapsed time is greater than the specified time), the microcontroller 111 switches the control switch 112 to an off state, so that the laser diode 113 stops emitting laser light. On the other hand, if the response signal is received within the specified time, the laser diode 113 is continuously driven to send laser light.

光源發射器110在持續發送雷射光的期間，會一直判斷是否有收到顯示裝置120的回應訊號。據此，一旦雷射光不是照射在顯示裝置120時，光源發射器110便會停止發送雷射光。The light source emitter 110 will always determine whether a response signal from the display device 120 is received during the period of continuously transmitting the laser light. Accordingly, once the laser light is not irradiated on the display device 120 , the light source emitter 110 will stop transmitting the laser light.

另外，光源發射器110中還可進一步設置功能鍵。功能鍵可與激發鍵整合為一個按鍵，亦可以為不同的按鍵。在功能鍵被致能的情況下，微控制器111可透過無線通訊模組115來傳送功能鍵碼給顯示裝置120，使得顯示裝置120根據功能鍵碼來執行對應的操作。In addition, the light source emitter 110 may further be provided with function keys. The function key and the activation key can be integrated into one key, or can be different keys. When the function key is enabled, the microcontroller 111 can transmit the function key code to the display device 120 through the wireless communication module 115 , so that the display device 120 performs the corresponding operation according to the function key code.

在顯示裝置120中，透過顯示面板126的光學觸控模組122來偵測是否接收到雷射光。在接收到雷射光時，光學觸控模組122例如可傳送感光（light on）訊息至處理器121。而在光學觸控模組122傳送感光訊息至處理器121之後，倘若在判定未持續接收到雷射光時，光學觸控模組122還可傳送無感光（light off）訊息至處理器121。In the display device 120 , whether the laser light is received is detected through the optical touch module 122 of the display panel 126 . When receiving the laser light, the optical touch module 122 may, for example, transmit a light on signal to the processor 121 . After the optical touch module 122 transmits the light-sensitive information to the processor 121 , if it is determined that the laser light is not continuously received, the optical touch module 122 can also transmit a light off signal to the processor 121 .

處理器121在接收到感光訊息後，將計時器的計數時間歸零並啟動計時器來計數時間。之後，處理器121判斷是否接收到無感光訊息。若接收到無感光訊息，則結束本次的處理流程。若沒有接收到無感光訊息，代表雷射光正照射在顯示面板126上。接著，處理器121判斷是否透過無線通訊模組123接收到確認鍵碼。在處理器121接收到確認鍵碼之後，處理器121傳送座標請求指令至顯示面板126，以自顯示面板126接收光點座標，以執行光點座標上的功能。After receiving the photosensitive information, the processor 121 resets the counting time of the timer to zero and starts the timer to count the time. Afterwards, the processor 121 determines whether a no-light-sensing message is received. If a no-photosensitive message is received, this processing flow ends. If no light-sensitive message is received, it means that the laser light is irradiating on the display panel 126 . Next, the processor 121 determines whether the confirmation key code is received through the wireless communication module 123 . After the processor 121 receives the confirmation key code, the processor 121 transmits a coordinate request command to the display panel 126 to receive the coordinates of the light spot from the display panel 126 to execute the function on the coordinates of the light spot.

在圖1中，將光源發射器110的發射點以A表示，在第一時間點發射的雷射光以L11表示，將光源發射器110在第二時間點發射的雷射光以L12表示。而雷射光L11在顯示裝置120上形成光點C，雷射光L12在顯示裝置120上形成光點B。In FIG. 1 , the emission point of the light source transmitter 110 is represented by A, the laser light emitted at the first time point is represented by L11, and the laser light emitted by the light source transmitter 110 at the second time point is represented by L12. The laser light L11 forms a light spot C on the display device 120 , and the laser light L12 forms a light spot B on the display device 120 .

在本實施例中，光源發射器110可設定為每隔一指定時間便執行測距功能來計算光源傳輸距離，並將光源傳輸距離傳送至顯示裝置120。並且，顯示裝置120同時設定為：光學觸控面板122自偵測到雷射光起每隔所述指定時間將雷射光落在顯示面板126的光點的座標傳送給處理器121。In this embodiment, the light source transmitter 110 may be configured to perform a distance measurement function every specified time to calculate the light source transmission distance, and transmit the light source transmission distance to the display device 120 . Moreover, the display device 120 is also set so that the optical touch panel 122 transmits the coordinates of the spot where the laser light falls on the display panel 126 to the processor 121 at the specified time interval since the optical touch panel 122 detects the laser light.

The coordinates of the first light spot are the coordinates of the light spot C. In step S415, at the second time point, the second light source transmission distance SB of the laser light L12 emitted by the light source transmitter 110 toward the display device 120 is calculated through the ranging function of the light source transmitter 110, and the second light source transmission distance SB is transmitted to Display device 120 .

在獲得垂直點D的座標(x3, y3)之後，基於垂直點D的座標(x3, y3)與第一直角邊的邊長SE來計算發射點A的位置（即光源發射器110的位置）。After obtaining the coordinates (x3, y3) of the vertical point D, the position of the emission point A (ie, the position of the light source emitter 110) is calculated based on the coordinates (x3, y3) of the vertical point D and the side length SE of the first right-angled side. .

據此，運用光源發射器110的測距功能，透過光源發射器110的雷射光在顯示裝置120上任意移動的兩個光點，便可進行光源發射器110的定位。Accordingly, using the ranging function of the light source transmitter 110 , the positioning of the light source transmitter 110 can be performed through two light spots of the laser light of the light source transmitter 110 that move arbitrarily on the display device 120 .

圖7是依照本發明一實施例的定位空間的示意圖。請參照圖7，在本實施例中，定位空間700可依系統軟體進行設定，定位空間700的範圍可大於顯示裝置120的尺寸。在此，方向D _G為指向顯示裝置120下方的方向，方向D _U為光源發射器110的方向，雷射光L71、L72為在不同時間點所發射的雷射光。顯示裝置120可利用光源發射器110在兩個不同時間點於定位空間700內所發射的雷射光來定位光源發射器110的位置。 FIG. 7 is a schematic diagram of a positioning space according to an embodiment of the present invention. Referring to FIG. 7 , in this embodiment, the positioning space 700 can be set according to the system software, and the range of the positioning space 700 can be larger than the size of the display device 120 . Here, the direction D _G is the direction pointing downward of the display device 120 , the direction D _U is the direction of the light source emitter 110 , and the laser lights L71 and L72 are laser lights emitted at different time points. The display device 120 can use the laser light emitted by the light source emitter 110 in the positioning space 700 at two different time points to locate the position of the light source emitter 110 .

而在獲得光源發射器110的位置之後，還可進一步透過顯示裝置120來自動調整周邊裝置的功能。例如，周邊裝置為揚聲器125。After the position of the light source emitter 110 is obtained, the function of the peripheral device can be further adjusted automatically through the display device 120 . For example, the peripheral device is the speaker 125 .

一般使用者家用的顯示器喇叭或家庭劇院系統會因客廳的格局和深度有所不同，加上使用者所坐的位置不同，會造成音場、音效非最佳化。例如，電視的左邊是牆、右邊是走道或是相反。而透過上述光源定位方法，搭配光源發射器110上的收音器116和無線通訊模組115，來啟動顯示裝置120的音效晶片124的音場、音效自動校正，改變聲音的平衡、相位對空間進行精確補償，然後運用動態定位功能來改變偏移值，讓使用者所在位置可以得到最佳的音場和音效。Generally, the monitor speakers or home theater systems used by users at home will be different due to the layout and depth of the living room, and the different positions of the users will cause the sound field and sound effects to be non-optimized. For example, the left side of the TV is the wall, the right side is the aisle, or vice versa. Through the above-mentioned light source positioning method, in conjunction with the radio 116 on the light source transmitter 110 and the wireless communication module 115, the sound field and sound effects of the sound effect chip 124 of the display device 120 are activated to automatically calibrate the sound field and sound effects, and the balance and phase of the sound are changed to perform spatial adjustment. Precisely compensate, and then use dynamic positioning to change the offset value so that the user's location can get the best soundstage and sound.

圖8是依照本發明一實施例的調整揚聲器輸出的示意圖。請同時參照圖3及圖8，在本實施例中，揚聲器125包括音箱801、802。音箱801、802設置在顯示裝置120的兩側。顯示裝置120在獲得光源發射器110的位置之後，可進一步來自動調整揚聲器125的輸出，即音箱801、802兩者的輸出。FIG. 8 is a schematic diagram of adjusting speaker output according to an embodiment of the present invention. Please refer to FIG. 3 and FIG. 8 at the same time. In this embodiment, the speaker 125 includes sound boxes 801 and 802 . Speakers 801 and 802 are provided on both sides of the display device 120 . After obtaining the position of the light source emitter 110 , the display device 120 can further automatically adjust the output of the speaker 125 , that is, the outputs of both the sound boxes 801 and 802 .

進一步地說，在光源發射器110中設置一功能鍵用來執行聲音自動校正功能。在致能所述功能鍵後，如上述光源定位方法所述，顯示裝置120可根據任意兩個光點來獲得光源發射器110的位置，之後，依據光源發射器110的位置來調整左音箱801與右音箱802兩者輸出聲的左右平衡和相位，並從音箱801與音箱802依序發出特定聲音。而顯示裝置120依據光源發射器110的收音器116接收到的聲音對空間做校正補償。Further, a function key is provided in the light source transmitter 110 for executing the automatic sound correction function. After the function keys are enabled, as described in the light source positioning method, the display device 120 can obtain the position of the light source emitter 110 according to any two light points, and then adjust the left speaker 801 according to the position of the light source emitter 110 Both the right speaker 802 and the right speaker 802 output the left and right balance and phase of the sound, and a specific sound is emitted from the speaker 801 and the speaker 802 in sequence. The display device 120 performs correction and compensation for the space according to the sound received by the sound receiver 116 of the light source transmitter 110 .

運用光源發射器110的測距功能，透過光源發射器110在不同時間點的雷射光L81、L82在顯示裝置120上形成的兩個光點，便可進行光源發射器110的定位。顯示裝置120可進一步基於光源發射器110的位置來調整音箱801、802兩者輸出的偏移值。Using the ranging function of the light source transmitter 110 , the positioning of the light source transmitter 110 can be performed through the two light spots formed on the display device 120 by the laser light L81 and L82 of the light source transmitter 110 at different time points. The display device 120 may further adjust the offset values output by the sound boxes 801 and 802 based on the position of the light source emitter 110 .

另外，還可透過顯示裝置120來調整顯示裝置120正在執行的遊戲的遊戲場景方向。圖9是依照本發明一實施例的調整顯示畫面的示意圖。請參照圖9，顯示裝置120現場一遊戲的遊戲場景。運用光源發射器110的測距功能，透過光源發射器110在不同時間點的雷射光L91、L92在顯示裝置120上形成的兩個光點，便可進行光源發射器110的定位。In addition, the direction of the game scene of the game being executed by the display device 120 can also be adjusted through the display device 120 . FIG. 9 is a schematic diagram of adjusting a display screen according to an embodiment of the present invention. Referring to FIG. 9 , the display device 120 displays a game scene of a live game. Using the ranging function of the light source transmitter 110 , the positioning of the light source transmitter 110 can be performed through the two light spots formed on the display device 120 by the laser lights L91 and L92 of the light source transmitter 110 at different time points.

啟動遊戲後，使用者坐於顯示裝置120的前方，觸發光源發射器110發射雷射光使得光點在顯示裝置120上隨意移動來進行定位，來獲得光源發射器110的位置。而雷射光的光點可隨意移動（例如依遊戲場景內容移動）。另外，顯示裝置120計算出光源發射器110的雷射光L91產生的直線與顯示裝置120的平面產生夾角θ，並將此夾角傳送給遊戲主機端（可設置在顯示裝置120亦可額外設置），使得遊戲主機端可運用此夾角θ來改變遊戲場景方向，可讓遊戲更有臨場感。After starting the game, the user sits in front of the display device 120 and triggers the light source emitter 110 to emit laser light so that the light spot moves randomly on the display device 120 for positioning to obtain the position of the light source emitter 110 . The spot of the laser light can move at will (for example, according to the content of the game scene). In addition, the display device 120 calculates the included angle θ between the straight line generated by the laser light L91 of the light source emitter 110 and the plane of the display device 120, and transmits the included angle to the game console (which can be set on the display device 120 or additionally set), The game host side can use this included angle θ to change the direction of the game scene, which can make the game more immersive.

另外，利用上述光源定位方法還可進一步識別出多個使用者的所在位置，並且運用在多個方面。例如，可運用在調整影像擷取裝置（周邊裝置）。圖10是依照本發明一實施例的調整影像擷取裝置的示意圖。請參照圖10，在本實施例中，顯示裝置120外接一影像擷取裝置1010。顯示裝置120的處理器121可透過有線或無線的傳輸方式來控制影像擷取裝置1010的致能與否以及調整影像擷取裝置1010的拍攝方向等。In addition, the above-mentioned light source positioning method can further identify the locations of multiple users, and can be used in multiple aspects. For example, it can be used to adjust the image capture device (peripheral device). FIG. 10 is a schematic diagram of adjusting an image capturing device according to an embodiment of the present invention. Referring to FIG. 10 , in this embodiment, the display device 120 is externally connected to an image capturing device 1010 . The processor 121 of the display device 120 can control whether the image capturing device 1010 is enabled or not and adjust the shooting direction of the image capturing device 1010 through wired or wireless transmission.

在啟動影像擷取裝置1010的視訊功能的情況下，使用者U利用運用光源發射器110在不同時間點發出雷射光L101、L102。顯示裝置120利用雷射光L101、L102來獲得光源發射器110的位置（代表使用者U的所在位置）之後，便可基於光源發射器110的位置來調整影像擷取裝置1010的拍攝方向。如圖10所示，顯示裝置120會控制影像擷取裝置1010轉動角度R使得其拍攝方向對準光源發射器110。When the video function of the image capture device 1010 is activated, the user U uses the light source emitter 110 to emit the laser lights L101 and L102 at different time points. After the display device 120 uses the laser lights L101 and L102 to obtain the position of the light source emitter 110 (representing the position of the user U), the shooting direction of the image capture device 1010 can be adjusted based on the position of the light source emitter 110 . As shown in FIG. 10 , the display device 120 controls the image capturing device 1010 to rotate by an angle R so that the shooting direction thereof is aligned with the light source emitter 110 .

據此，運用所述光源定位方法，找出使用光源發射器110的使用者的位置，藉此讓影像擷取裝置迅速和精確地對準使用者，可避免在多人場景或多人說話的情況下所產生的錯亂和誤差，當用雷射筆簡報的過程中更直接、更準確、更便利。Accordingly, by using the light source positioning method, the position of the user using the light source emitter 110 can be found out, so that the image capture device can be quickly and accurately aimed at the user, which can avoid the situation where there are many people or people talking. The confusion and errors generated by the situation are more direct, more accurate and more convenient when using the laser pen to brief the process.

此外，上述光源定位方法還可運用於射擊遊戲上。利用上述光源定位方法分別識別出多個使用者的所在位置，在遊戲進行時搭配功能鍵後即可瞄準射擊並獨立計分，此方式更直覺，反應速度更快、臨場感更好。In addition, the above-mentioned light source positioning method can also be applied to shooting games. The above-mentioned light source positioning method is used to identify the positions of multiple users, and when the game is in progress, after matching the function keys, you can aim and shoot and score independently.

綜上所述，本揭露運用雷射光的可測距特性進行定位，使得顯示裝置的應用更加多元化，並且可用於聲學的音效、音場調整或校正，更可應用於遊戲，讓大屏的顯示裝置應用可以更加多元。To sum up, the present disclosure utilizes the distance measurement characteristic of laser light for positioning, which makes the application of display devices more diversified, and can be used for acoustic sound effects, sound field adjustment or correction, and can be applied to games, so that large-screen display devices can be adjusted or corrected. Display device applications can be more diverse.
