However, the use environment of display device is relatively complex, especially the ambient light brightness. In the environment with sufficient sunlight, the ambient light brightness is relatively high, while in the environment at night, the ambient light brightness is relatively low. The ambient light brightness will affect the viewing effect of the user. When the ambient light brightness is relatively high, it is difficult to see the real picture of the display device clearly, and when the ambient light brightness is relatively low, the picture brightness of the display device may make the user feel relatively dazzling. Therefore, the display device increases the light sensing function, which can automatically adjust the backlight brightness of the display device according to the brightness of the ambient light. Thus, the user can have a good viewing effect under different ambient light conditions.

[0124] In some embodiments, the user can input user commands through the graphical user interface (GUI) displayed on the display 275, and the user input interface receives the user input commands through the graphical user interface (GUI). Alternatively, the user can input user commands by inputting specific sounds or gestures, and the user input interface receives the user input commands by recognizing the sounds or gestures through sensors.

[0125] In some embodiments, a "user interface" is the medium through which an application or operating system interacts and exchanges information with a user, converting information between its internal form and a form acceptable to the user. A common form of user interface is the graphical user interface (GUI), which refers to a user interface related to computer operation displayed graphically. It can be an icon, window, control, or other interface element displayed on the screen of an electronic device. Controls can include visual interface elements such as icons, buttons, menus, tabs, text boxes, dialog boxes, status bars, navigation bars, and widgets.

For example, the various software modules stored in the first memory include at least one of the following: a basic module, a detection module, a communication module, a display control module, a browser module, and various service modules.

[0127] The basic module is a low-level software module used for signal communication between various hardware components in the display device 200 and for sending processing and control signals to higher-level modules. The detection module is a management module used to collect various information from various sensors or user input interfaces, perform digital-to-analog conversion, and analyze and manage the data.

[0129] Figure 3 An exemplary block diagram of the configuration of the control device 100 according to an exemplary embodiment is shown. Figure 3 As shown, the control device 100 includes a controller 110, a communication interface 130, a user input / output interface, a memory, and a power supply.

[0130] The control device 100 is configured to control the display device 200, and to receive user input commands, converting the commands into commands that the display device 200 can recognize and respond to, thus acting as an intermediary for interaction between the user and the display device 200. For example, if the user operates the channel up / down keys on the control device 100, the display device 200 will respond with the channel up / down operation.

[0131] In some embodiments, the control device 100 can be a smart device. For example, the control device 100 can install various applications for controlling the display device 200 according to user needs.

[0132] In some embodiments, as shown in FIG. 3, the mobile terminal 300 or other smart electronic device can play a similar function of the control device 100 after installing the application for controlling the display device 200. For example, the user can install the application to provide various function keys or virtual buttons on the graphical user interface of the mobile terminal 300 or other smart electronic device to realize the function of the physical keys of the control device 100. Figure 1

[0133] The controller 110 includes a processor 112 and a RAM 113 and a ROM 114, a communication interface 130, and a communication bus. The controller is used to control the operation and operation of the control device 100, and the communication and cooperation between the internal components and the external and internal data processing functions.

[0134] The communication interface 130 is controlled by the controller 110 to realize the communication of control signals and data signals between the display device 200. For example, the received user input signal is sent to the display device 200. The communication interface 130 can include at least one of a WiFi chip 131, a Bluetooth module 132, an NFC module 133, and other near field communication modules.

[0135] The user input / output interface 140, wherein the input interface includes at least one of a microphone 141, a touchpad 142, a sensor 143, a key 144, and other input interfaces. For example, the user can realize the user instruction input function through voice, touch, gesture, pressing, etc. The input interface converts the received analog signal into a digital signal, and the digital signal into a corresponding instruction signal, and sends it to the display device 200.

[0136] The output interface includes an interface for sending the received user instruction to the display device 200. In some embodiments, it can be an infrared interface or a radio frequency interface. For example, when the infrared signal interface, the user input instruction needs to be converted into an infrared control signal according to the infrared control protocol, and sent to the display device 200 by the infrared sending module. For example, when the radio frequency signal interface, the user input instruction needs to be converted into a digital signal, and then modulated according to the radio frequency control signal modulation protocol, and then sent to the display device 200 by the radio frequency sending terminal.

[0137] ​In some embodiments, the control device 100 comprises at least one of a communication interface 130 and an input / output interface 140. The communication interface 130, such as a WiFi, Bluetooth, NFC, etc. module, is configured in the control device 100 to encode and send user input instructions to the display device 200 via a WiFi protocol, or a Bluetooth protocol, or an NFC protocol.

[0138] A memory 190 is configured to store various running programs, data and applications for driving and controlling the control device 200 under the control of the controller. The memory 190 can store various control signal instructions input by the user.

[0139] A power supply 180 is configured to provide operating power support for various elements of the control device 100 under the control of the controller. The power supply 180 can be a battery and related control circuit.

[0140] In some embodiments, the system can include a kernel, a shell, a file system and an application. The kernel, the shell and the file system together form a basic operating system structure, which allows the user to manage files, run programs and use the system. After power-on, the kernel starts, activates the kernel space, abstracts hardware, initializes hardware parameters, runs and maintains virtual memory, schedulers, signals and inter-process communication (IPC). After the kernel starts, the shell and user applications are loaded. The application is compiled into machine code after starting, forming a process.

[0141] Referring to Figure 4 In some embodiments, the system is divided into four layers from top to bottom, namely an application layer (referred to as "application layer" for short), an application framework layer (referred to as "framework layer" for short), an Android runtime and system library layer (referred to as "system runtime library layer" for short), and a kernel layer.

[0142] In some embodiments, at least one application program is running in the application layer, which can be a window (Window) program, a system setting program, a clock program, a camera application, etc. provided by the operating system. It can also be an application program developed by a third-party developer, such as a Hi-See program, a K-song program, a magic mirror program, etc. In specific implementation, the application program package in the application layer is not limited to the above examples, and other application program packages can also be included, which are not limited by the embodiments of the present application.

[0143] The framework layer provides application programming interfaces (APIs) and programming frameworks for applications in the application layer. The application framework layer includes some pre-defined functions. The application framework layer is equivalent to a processing center that decides which application in the application layer to act. The application accesses resources in the system and obtains services of the system in execution through the API interface

[0144] As shown in Figure 4 the application embodiment, the application framework layer includes managers (Managers) and content providers (Content Provider), wherein the managers include at least one of the following modules: an activity manager (ActivityManager) for interacting with all activities running in the system. A location manager (Location Manager) for providing access to system location services for system services or applications. A package manager (Package Manager) for retrieving various information related to application packages currently installed on the device. A notification manager (NotificationManager) for controlling the display and clearing of notification messages. A window manager (Window Manager) for managing icons, windows, toolbars, wallpapers and desktop components on the user interface.

[0145] In some embodiments, the activity manager is used to manage the life cycle of each application and the general navigation back function, such as controlling the exit of the application (including switching the user interface currently displayed in the display window to the system desktop), opening, back (including switching the user interface currently displayed in the display window to the upper level user interface of the currently displayed user interface) and the like.

[0146] In some embodiments, the window manager is used to manage all window programs, such as obtaining the size of the display screen, determining whether there is a status bar, locking the screen, intercepting the screen, controlling the change of the display window (such as reducing the display of the display window, shaking the display, twisting the display, etc.) and the like.

[0147] In some embodiments, the system runtime library layer provides support for the upper layer, i.e., the framework layer. When the framework layer is used, the Android operating system runs the C / C++ library contained in the system runtime library layer to realize the functions of the framework layer.

[0148] In some embodiments, the kernel layer is the layer between hardware and software. As Figure 4As shown, the kernel layer at least contains at least one of the following drivers: an audio driver, a display driver, a Bluetooth driver, a camera driver, a WIFI driver, a USB driver, an HDMI driver, a sensor driver (such as a fingerprint sensor, a temperature sensor, a touch sensor, a pressure sensor, etc.), and the like.

[0149] In some embodiments, the kernel layer further comprises a power supply driving module for power management.

[0150] In some embodiments, Figure 4 The software programs and / or modules corresponding to the software architecture in Figure 2 or Figure 3 are stored in the first memory or the second memory as shown.

[0151] In some embodiments, taking a magic mirror application (a photographing application) as an example, when the remote control receiving device receives an input operation of the remote controller, a corresponding hardware interrupt is given to the kernel layer. The kernel layer processes the input operation into a raw input event (including the value of the input operation, the timestamp of the input operation, and the like). The raw input event is stored in the kernel layer. The application framework layer obtains the raw input event from the kernel layer, identifies the control corresponding to the input event according to the current position of the focus, and identifies that the input operation is a confirmation operation. The control corresponding to the confirmation operation is the control of the magic mirror application icon. The magic mirror application calls the interface of the application framework layer, starts the magic mirror application, and then starts the camera driver by calling the kernel layer, so as to realize capturing a still image or a video through the camera.

[0152] In some embodiments, for a display device with a touch function, taking a split-screen operation as an example, the display device receives an input operation (such as a split-screen operation) of a user acting on the display screen. The kernel layer can generate a corresponding input event according to the input operation and report the event to the application framework layer. The activity manager of the application framework layer sets the window mode (such as a multi-window mode) corresponding to the input operation, as well as the window position and size, and the like. The window manager of the application framework layer draws the window according to the setting of the activity manager, and then sends the drawn window data to the display driver of the kernel layer, so as to display the corresponding application interface in different display areas of the display screen by the display driver.

[0153] In some embodiments, as shown in Figure 5 The application layer contains at least one application program, which can display corresponding icon controls in the display, such as: a live TV application icon control, a video on demand application icon control, a media center application icon control, an application center icon control, a game application icon control, and the like.

[0154] In some embodiments, a live television application can provide live television through different signal sources. For example, a live television application can use input from a cable television, a radio broadcast, a satellite service, or other types of live television services to provide television signals. Also, a live television application can display video of the live television signals on the display device 200.

[0155] In some embodiments, a video on demand application can provide video from different storage sources. Unlike a live television application, a video on demand provides video displays from certain storage sources. For example, a video on demand can come from a server side of a cloud storage, from a local hard drive storage containing stored video programs.

[0156] In some embodiments, a media center application can provide various multimedia content playing applications. For example, a media center can provide services for users to access various image or audio services through the media center application, which are different from live television or video on demand.

[0157] In some embodiments, an application center can provide storage for various applications. An application can be a game, an application, or other applications that are related to a computer system or other devices but can run in a smart television. The application center can obtain these applications from different sources, store them in a local storage, and then make them available for running on the display device 200.

[0158] In recent years, with the development of display device technology, display devices such as liquid crystal televisions are usually provided with light sensing devices to detect the ambient brightness of the display device in real time. Thus, the display device can adjust the backlight brightness of the display according to the change of the ambient brightness, bringing good viewing effect to the user. However, due to the complex use environment of the display device, for example, the user can be a family of four, two adults and two children. When using the display device, the children may play or run in the area near the display device, if the child happens to block the light sensing device, the ambient brightness detected by the light sensing device is not the original ambient brightness, but the ambient brightness after being blocked by the child. At this time, the ambient brightness is darker than the original ambient brightness. Thus, when the display device adjusts the backlight brightness of the display according to the ambient brightness, it will incorrectly lower the backlight brightness, reducing the viewing effect of the user. Thus, the current display device has low accuracy when adjusting the backlight brightness of the display.

[0159] Based on the above, on the basis of the above embodiments, in order to solve the above technical problems, the inventors have found that, by combining the ambient light brightness of another device, the accuracy of adjusting the backlight brightness of the display device can be improved by the ambient light brightness of the other device and the ambient light brightness of the display device. The device needs to meet two conditions at the same time, one of which is close to the display device, when the device is close to the display device, the ambient light brightness of the device is closer to the ambient light brightness of the display device. The second is that the device is difficult to be blocked, so that the ambient light brightness detected by the device is the original ambient light brightness, and the accuracy is higher. Therefore, the inventors have determined through careful research that the device is a control device of the display device, and the control device is almost not blocked when in use in order to achieve better control effect, and the control device is close to the display device. Therefore, the embodiment of the present application provides a display device, which sets a light sensing device on the display device and the control device to control the backlight brightness of the display according to the ambient light brightness detected by the control device and the ambient light brightness detected by the display device, and improve the accuracy of controlling the backlight brightness. Specifically, the display device receives the first ambient light brightness sent by the first light sensing device through the controller connected with the first light sensing device. The second ambient light brightness sent by the control device is received. The original ambient light brightness is divided into a plurality of ambient light brightness ranges according to brightness. The second ambient light brightness is sent to the first controller when the control device determines that the ambient light brightness range to which the second ambient light brightness belongs and the ambient light brightness range to which the third ambient light brightness belongs are different. The third ambient light brightness is the ambient light brightness detected by the second light sensing device of the control device before detecting the second ambient light brightness. The backlight brightness of the display is controlled according to the first ambient light brightness and the second ambient light brightness. Thus, the problem of low accuracy in adjusting the backlight brightness of the display device is overcome.

[0160] The display device provided by the embodiment of the present application comprises:

[0161] The display.

[0162] The first light sensing device is used for detecting the first ambient light brightness of the display.

[0163] The first communication device is used for establishing a wireless communication link between the control device for controlling the display and the first controller.

[0164] The first controller connected with the first light sensing device is configured to:

[0165] Receive the first ambient light brightness sent by the first light sensing device.

[0166] The second ambient light brightness is received from the control device. The native ambient light brightness is divided into a plurality of ambient light brightness ranges according to brightness. The second ambient light brightness is sent to the first controller when the control device determines that the ambient light brightness range to which the second ambient light brightness belongs is different from the ambient light brightness range to which the third ambient light brightness belongs. The third ambient light brightness is the last detected ambient light brightness detected by the second light sensing device of the control device before the second ambient light brightness is detected.

[0167] The backlight brightness of the display is controlled according to the first ambient light brightness and the second ambient light brightness.

[0168] In some embodiments, the use scenario between the display device and the control device is as shown in Figure 6 The display device and the control device are each provided with a light sensing device, i.e., the first light sensing device in the display device and the second light sensing device in the control device. The wireless communication link can be any short-range wireless communication link, such as Bluetooth, infrared, WiFi, etc.

[0169] In some embodiments, the native ambient light brightness is distinguished from the first ambient light brightness and the second ambient light brightness, and refers to the ambient light brightness itself. When adjusting the backlight brightness of the display, the display device generally adjusts the backlight brightness of the display according to the ambient light brightness range to which the ambient light brightness of the display device belongs. For example, the native ambient light brightness is divided into 10 ambient light brightness ranges, and each ambient light brightness range corresponds to a backlight brightness of the display.

[0170] In some embodiments, the first light sensing device detects the ambient light brightness of the display device in real time and sends each detected ambient light brightness to the first controller. The first controller saves the ambient light brightness sent by the first light sensing device before the next ambient light brightness is sent by the first light sensing device. The control device can be a remote controller of the display device or other devices that control the display device. At the same time, the second light sensing device in the control device also detects the ambient light brightness of the control device in real time and sends it to the second controller in the control device.

[0171] The control device sends the second ambient light brightness to the first controller when the ambient light brightness range to which the current ambient light brightness, i.e., the second ambient light brightness, belongs is different from the ambient light brightness range to which the last ambient light brightness, i.e., the third ambient light brightness, belongs. When the ambient light brightness range to which the second ambient light brightness belongs is different from the ambient light brightness range to which the third ambient light brightness belongs, it means that the ambient light brightness range to which the ambient light brightness of the display device belongs has also changed, and the backlight brightness of the display needs to be adjusted.

[0172] For example, as shown in Figure 7 and Figure 8As shown, taking the display device as a television and the control device as a remote controller as an example, the data transmission and data processing between the display device and the control device are illustrated.

[0173] The television and the remote controller can establish communication through Bluetooth, infrared and the like, and in the embodiment, communication is established through a Bluetooth module. The remote controller comprises a second light sensing device, a second controller and a remote controller Bluetooth module (i.e. a second communicator), and the television comprises a first light sensing device, a first controller and a television Bluetooth module (i.e. a first communicator). After the remote controller and the television complete connection, pairing and binding through the Bluetooth protocol, a data communication link is established. The specific implementation process is as follows:

[0174] Step S501, after the television opens the Bluetooth switch, it is in a broadcast state as a slave and starts a device discovery process.

[0175] Step S502, the remote controller as a master device sends a scan request to the slave television after receiving the broadcast.

[0176] Step S603, the slave television returns a scan response to the master after receiving the scan request, and thus the device discovery process ends.

[0177] Step S504, the master remote controller sends a connection request to the slave television, and starts a connection process.

[0178] Step S505, after the connection is completed, pairing is performed, and an encryption and authentication key is generated in the pairing process to pair according to the key.

[0179] Step S506, a binding process is started, and after the master and slave are bound, the next connection can be quickly paired.

[0180] Step S507, the second light sensing device in the remote controller detects the ambient light brightness in which the remote controller is located in real time. The second controller in the remote controller determines whether to send the second ambient light brightness according to the ambient light brightness range to which the second ambient light brightness belongs and the ambient light brightness range to which the third ambient light brightness belongs.

[0181] Step S508, after it is determined to send the second ambient light brightness, the remote controller sends the second ambient light brightness to the television Bluetooth module of the television through the remote controller Bluetooth module.

[0182] Step S509, the first light sensing device of the television detects the ambient light brightness in which the television is located in real time, and at the same time, the first controller of the television controls the backlight brightness of the display according to the first ambient light brightness and the second ambient light brightness.

[0183] In some embodiments, the first controller is specifically configured to:

[0184] determine whether the ambient light brightness range to which the first ambient light brightness belongs is the same as the ambient light brightness range to which the second ambient light brightness belongs.

[0185] control the backlight brightness of the display according to the determination result.

[0186] In the embodiment, if the ambient light brightness range to which the first ambient light brightness belongs is the same as the ambient light brightness range to which the second ambient light brightness belongs, it means that the ambient light brightness to which the control device is subjected is the same as the ambient light brightness to which the display device is subjected. If the ambient light brightness range to which the first ambient light brightness belongs is different from the ambient light brightness range to which the second ambient light brightness belongs, it means that there is an occlusion phenomenon in the control device and the display device.

[0187] In some embodiments, the first controller is specifically configured to:

[0188] If the determination result is that the ambient light brightness range to which the first ambient light brightness belongs is the same as the ambient light brightness range to which the second ambient light brightness belongs, the backlight brightness of the display is adjusted according to the ambient light brightness range to which the first ambient light brightness belongs.

[0189] If the determination result is that the ambient light brightness range to which the first ambient light brightness belongs is different from the ambient light brightness range to which the second ambient light brightness belongs, the backlight brightness of the display is maintained unchanged.

[0190] In the embodiment, if the ambient light brightness range to which the first ambient light brightness belongs is the same as the ambient light brightness range to which the second ambient light brightness belongs, it means that the ambient light brightness to which the control device is subjected is the same as the ambient light brightness to which the display device is subjected. Since the second ambient light brightness is sent to the first controller after the control device determines that the ambient light brightness range changes, the ambient light brightness range of the display device also changes accordingly, and the backlight brightness of the display can be adjusted according to the ambient light brightness range to which the first ambient light brightness belongs. If the determination result is that the ambient light brightness range to which the first ambient light brightness belongs is different from the ambient light brightness range to which the second ambient light brightness belongs, it means that there is an occlusion phenomenon in the control device and the display device. Generally, the display device is occluded, and thus the backlight brightness of the display needs to be maintained unchanged at this time.

[0191] In some embodiments, the first controller is further configured to:

[0192] determine whether the ambient light brightness range to which the first ambient light brightness belongs is the same as the ambient light brightness range to which the fourth ambient light brightness belongs. The fourth ambient light brightness is the ambient light brightness sent by the first light sensing device before the first ambient light brightness is sent.

[0193] If the ambient light range to which the first ambient light brightness belongs is determined to be different from the ambient light range to which the fourth ambient light brightness belongs, then the backlight brightness of the display is controlled according to the first and second ambient light brightness.

[0194] Meanwhile, the first controller is also configured as follows:

[0195] If it is determined that the ambient light range to which the first ambient light brightness belongs is the same as the ambient light range to which the fourth ambient light brightness belongs, then the backlight brightness of the display remains unchanged.

[0196] In this embodiment, the first light sensor in the display device detects the ambient light brightness at the display device in real time and sends it to the first controller. The fourth ambient light brightness is the ambient light brightness sent by the first light sensor before sending the first ambient light brightness. For example, if the first light sensor sends three ambient light brightness values ​​a, b, and c in sequence, and c is the first ambient light brightness, then b is the fourth ambient light brightness.

[0197] If the ambient light range to which the first ambient light brightness belongs is different from the ambient light range to which the fourth ambient light brightness belongs, it means that the ambient light range in which the display device is located has changed, and the backlight brightness of the monitor needs to be adjusted. If the ambient light range to which the first ambient light brightness belongs is the same as the ambient light range to which the fourth ambient light brightness belongs, it means that the ambient light range in which the display device is located has not changed, and in this case, it is not necessary to adjust the backlight brightness of the monitor.

[0198] In some embodiments, the first controller is further configured to:

[0199] If no second ambient light is received, the backlight brightness of the display will remain unchanged.

[0200] The control device only sends the second ambient light brightness when the ambient light brightness range to which the control device is located changes. When the second ambient light brightness is not received, it means that the ambient light brightness range to which the control device is located has not changed. Therefore, regardless of whether the ambient light brightness range to which the display device is located changes, the backlight brightness of the display remains unchanged to avoid incorrect backlight brightness adjustment caused by the display device being blocked.

[0201] For example, such as Figure 9 As shown, taking a television as the display device and a remote control as the control device, the process of adjusting the backlight brightness of a monitor is illustrated. Steps S602-S605 represent the process on the remote control side, and steps S606-S611 represent the process on the television side; both processes are performed simultaneously. The specific process is as follows:

[0202] Step S601, the ambient light changes at the television end or the remote control end.

[0203] Step S602, the light sensing device at the remote control end outputs the current ambient light brightness, i.e., the second ambient light brightness, to the second controller of the remote control.

[0204] Step S603, the second controller compares whether the ambient light brightness range to which the second ambient light brightness belongs is same as the ambient light brightness range to which the previous ambient light brightness belongs. If yes, step S604 is executed, and if no, step S605 is executed.

[0205] Step S604, the second ambient light brightness is not sent, and meanwhile, the second ambient light brightness is saved as the third ambient light brightness corresponding to the next ambient light brightness.

[0206] Step S605, the second controller sends the second ambient light brightness to the first communication device at the television end through the second communication device, and the first communication device sends the second ambient light brightness to the first controller.

[0207] Step S606, the light sensing device at the television outputs the current ambient light brightness, i.e., the first ambient light brightness, to the first controller of the television.

[0208] Step S607, the first controller compares whether the ambient light brightness range to which the first ambient light brightness belongs is same as the ambient light brightness range to which the previous ambient light brightness belongs. If yes, step S611 is executed, and if no, step S608 is executed.

[0209] Step S608, the first controller judges whether the second ambient light brightness sent by the remote control is received. If yes, step S609 is executed, and if no, step S611 is executed.

[0210] Step S609, the first controller compares whether the ambient light brightness range to which the first ambient light brightness belongs is same as the ambient light brightness range to which the second ambient light brightness belongs. If yes, step S610 is executed, and if no, step S611 is executed.

[0211] Step S610, the backlight brightness of the display is adjusted according to the ambient light brightness range to which the first ambient light brightness belongs.

[0212] Step S611, the backlight brightness of the display is maintained unchanged.

[0213] The embodiment of the present application further provides a control device, comprising:

[0214] The second communication device is configured to establish a wireless communication link between the second controller and the first controller of the display device.

[0215] A second light sensing device is configured to detect a second ambient light intensity of a second environment in which the control device is located.

[0216] A second controller connected to the second light sensing device is configured to:

[0217] receive the second ambient light intensity sent by the second light sensing device.

[0218] determine whether to send the second ambient light intensity to the first controller according to a range of ambient light intensities to which the second ambient light intensity belongs and a range of ambient light intensities to which a third ambient light intensity belongs, wherein the native ambient light intensity is divided into a plurality of ranges of ambient light intensities according to intensity, and the third ambient light intensity is an ambient light intensity sent by the second light sensing device before the second ambient light intensity is sent.

[0219] if it is determined to send, send the second ambient light intensity to the first controller, so that the first controller controls the backlight intensity of the display according to the second ambient light intensity and the first ambient light intensity.

[0220] The control device provided in the embodiments sends the second ambient light intensity to the display device when the range of ambient light intensities to which the second ambient light intensity belongs and the range of ambient light intensities to which the third ambient light intensity belongs change, so that the first controller of the display device controls the backlight intensity of the display according to the second ambient light intensity and the first ambient light intensity.

[0221] In some embodiments, the second controller is specifically configured to:

[0222] determine whether the range of ambient light intensities to which the second ambient light intensity belongs and the range of ambient light intensities to which the third ambient light intensity belongs are the same.

[0223] if it is determined that the range of ambient light intensities to which the second ambient light intensity belongs and the range of ambient light intensities to which the third ambient light intensity belongs are different, send the second ambient light intensity to the display device through the wireless communication link.
