Detailed Description
It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
An embodiment of the present invention provides a backlight control system, and referring to fig. 1, fig. 1 is a schematic structural diagram of an embodiment of the backlight control system of the present invention.
In this embodiment, the backlight control system includes:
a touch panel 100, the touch panel 100 being configured to receive touch information;
the key matrix 101 is arranged on the back side of the touch panel, and the key matrix 101 comprises a plurality of transverse key groups and a plurality of longitudinal key groups;
the backlight matrix 200 comprises a transverse light guide sheet, a longitudinal light guide sheet and a light source, wherein the transverse light guide sheet and the longitudinal light guide sheet are respectively arranged on one sides of the transverse key group and the longitudinal key group, which are far away from the touch panel, and at least one light source is arranged at the end parts of the transverse light guide sheet and the longitudinal light guide sheet;
a driving module 300, wherein the driving module 300 is configured to provide a driving current for the backlight matrix 200 to adjust the brightness of the backlight matrix 200, and the driving module 300 is electrically connected to the backlight matrix 200;
the system chip 400, the system chip 400 is electrically connected to the touch panel 100 and the driving module 300 respectively;
when the touch panel 100 receives touch information, the system chip 400 generates light control information according to the touch information and transmits the light control information to the driving module 300, so that the driving module adjusts the brightness of the corresponding light source in the backlight matrix according to the light control information.
It is understood that the touch panel 100 is an important component of the backlight control System, and is used for receiving information touched by a user and transmitting the information to a System On Chip (SOC) 400 for processing; according to the light emitting direction marked in fig. 1, the back side of the touch panel refers to a side of the touch panel that is not touched by a user, the key matrix 101 includes a plurality of touch keys, and the keys form a plurality of transverse key groups and a plurality of longitudinal key groups, which are explained based on a plane in this embodiment, the transverse direction refers to the horizontal direction, and the longitudinal direction refers to the vertical direction, which are only for describing and clarifying the relative position relationship of each key in the key matrix, and do not represent that the keys must be transversely or longitudinally arranged; the system chip 400 communicates with the driving module 300 through an I2C (Inter-Integrated Circuit) protocol, and through system settings, the backlight matrix 200 can be controlled to emit lights of different brightness and the LEDs can be controlled to be turned on and off individually according to the user's usage scenario; the driving module 300 provides driving current for the backlight matrix 200 to control the brightness of the LEDs in the backlight matrix, and assuming that the horizontal direction is X and the vertical direction is Y in this embodiment, the rated current of the LEDs is I X ,I Y (since most of the key matrix 101 is different in length and width, I is a value for making the horizontal and vertical luminance uniform as much as possible X Is slightly larger than I Y ). In addition, the present embodiment further includes a power supply module electrically connected to the system chip 400 for supplying power to the whole system, and a bluetooth module electrically connected to the system chip 400 as a connection link between the backlight control system and the external controlled device, where the bluetooth module is configured to transmit control information to the external controlled device, so as to complete related operations of the user. It should be understood that the electrical connection refers to the ability of the structures or modules to communicate electrical signals and communication signals with each other in electrical connection.
It should be noted that the backlight matrix in this embodiment is an RGB LED lamp effect matrix, and is composed of a transverse light guide sheet, a longitudinal light guide sheet, and light sources at ends of the transverse light guide sheet and the longitudinal light guide sheet, where the light sources are RGB LED lamps, rather than traditional white light LEDs. Generally, for user experience, when designing a key matrix, the number of rows of keys is large, and some keys may even be up to dozens of rows, but the number of keys in each row is indefinite, and the number of columns is small, and generally 3 to 4 columns. In the present embodiment, only one RGB LED backlight source needs to be disposed at each column and each row, so that only J + K backlight sources are needed.
As an example, in the present embodiment, the horizontal key set includes a horizontal standard key, and the vertical key set includes a vertical standard key; the transverse standard keys are positioned in the light emitting direction of the transverse light guide sheet, and the longitudinal standard keys are positioned in the light emitting direction of the longitudinal light guide sheet.
It can be understood that, in the present embodiment, the RGB LEDs are uniformly distributed on two sides of the light guide plate, so as to divide the light guide plate into a plurality of light guide regions. Referring to fig. 3, fig. 3 is a schematic diagram of the position distribution of the backlight matrix and the key matrix in this embodiment, where grid lines in fig. 3 represent a light guiding path of the light guiding sheet, where a light color point located in a middle area of a grid is a key position, dark color points located at a left edge and a lower edge of the grid are light source positions, and viewed along a light emitting direction, the horizontal light guiding sheet is overlapped with the horizontal standard key, the vertical light guiding sheet is overlapped with the vertical standard key, and the horizontal light guiding sheet is a row and a column and has a lower light source, i.e., a light source at an end of the vertical light guiding sheet, and a left light source, i.e., a light source at an end of the horizontal light guiding sheetThe side edges can be adjusted and combined according to actual needs. In fig. 3, the lower left corner is set as the origin of coordinates, the horizontal direction is defined as the X direction, and then the 4 LEDs in the X direction are respectively defined as X from left to right 1 ,X 2 ,…,X K Coordinates of (x1,0), (x2,0), …, (xk,0), and similarly, the vertical direction is defined as the Y direction, and the 18 lamps in the Y direction are defined as Y from bottom to top 1 ,Y 2 ,…,Y J The coordinates are (0, Y1), (0, Y2) … (0, yj), the LEDs in the X direction respectively illuminate the corresponding Y area in the vertical direction of each LED, namely X 1 When the LED display screen is lightened, the light paths of the first row of keys are all lightened, and the LEDs in the Y direction respectively lighten the X area in the vertical direction corresponding to each LED, namely Y 1 When the LED display screen is lightened, the light paths where the first row of keys are located are all lightened. The touch keys can be placed in the whole light guide area, generally, in order to better present the light guide effect, the touch keys are generally arranged at the intersection point parts of the LEDs on the two sides (i.e. the intersection points of the grid lines in fig. 3) as much as possible, the touch keys are arranged at the positions which are the transverse standard keys and the longitudinal standard keys, and the positions have higher brightness due to the superposition of the brightness.
It should be noted that the horizontal standard key corresponds to the horizontal light guide plate and the light source located in the Y direction, and the vertical standard key corresponds to the vertical light guide plate and the light source located in the X direction, and the light source and the backlight source in this embodiment have the same meaning.
As an example, in this embodiment, the horizontal key set further includes a horizontal non-standard key, and the vertical key set further includes a vertical non-standard key; the transverse non-standard keys are located between the light emitting directions of the transverse light guide sheets, and the longitudinal non-standard keys are located between the light emitting directions of the longitudinal light guide sheets.
It can be understood that, in general, the hardware device including the backlight control system as shown in fig. 2 has circular control areas, such as up, down, left, right and confirm buttons, and it is impossible to set all the buttons at the intersection of the light paths in order to ensure the overall symmetry and beauty of the device during the design process, therefore, in order to ensure the backlight effect, in this embodiment, such buttons are set at the middle positions of the two light sources in the X direction or the Y direction (although fig. 3 only shows the buttons set at the middle positions of the two light sources in the X direction, it does not mean that the buttons cannot be set at the middle positions of the two light sources in the Y direction), and the buttons set at such positions are non-standard buttons in one direction or two directions. It is understood that, after the above design, one key in the key matrix may correspond to one light source in the X direction and one light source in the Y direction (both the transverse standard key and the longitudinal standard key), may correspond to two light sources in the X direction and one light source in the Y direction (both the transverse standard key and the longitudinal non-standard key), may correspond to one light source in the X direction and two light sources in the Y direction (both the transverse non-standard key and the longitudinal standard key), and may correspond to two light sources in the X direction and two light sources in the Y direction (both the transverse non-standard key and the longitudinal non-standard key).
In this embodiment, a backlight control system is provided, where a RGB LED lighting effect matrix is used as a backlight matrix, the number of RGB LED backlight sources is set by referring to the number of keys in rows and columns in the key matrix, that is, each row or each column corresponds to only one backlight source, and a light guide plate is used to uniformly guide light emitted from the backlight sources in the rows and columns to the whole plane. When a touch event occurs, the backlight source only turns on the backlight source corresponding to the touch area, and does not turn on the whole backlight. On one hand, the method can be conveniently used by a user under a dark scene, and can confirm that the operation of the user is executed. On the other hand, only the light source in the corresponding area is lightened, so that the power consumption can be effectively reduced, and the service life of the battery is further prolonged.
The embodiment of the invention also provides a touch remote controller, which comprises the backlight control system, and referring to fig. 4, fig. 4 is a schematic structural diagram of an embodiment of the touch remote controller.
In this embodiment, the touch remote controller 10 further includes a motion detection module 500, and the motion detection module 500 is electrically connected to the system chip 400, and is configured to obtain a position change and a motion state of the touch remote controller 10.
It should be noted that the motion detection module 500 includes an angular motion detection device, such as a gyroscope (gyroscope), which may be a piezoelectric gyroscope, a micromechanical gyroscope, an optical fiber gyroscope, or a laser gyroscope in this embodiment, for acquiring the position change of the touch remote controller 10; the motion detection module 500 further includes an acceleration sensor, such as an accelerometer (accelerometer), for acquiring a motion state of the touch remote controller, where the accelerometer in this embodiment may be a linear accelerometer or a pendulum accelerometer.
In the embodiment, a touch remote controller is provided, in which a motion detection module electrically connected to a backlight control system is added to the touch remote controller, the motion detection module comprises a gyroscope and an accelerometer, can accurately detect the angle change of the touch remote controller in the horizontal direction and the vertical direction through the gyroscope, can accurately detect the speed change of the touch remote controller through the accelerometer, and both can reflect the change of the motion state of the touch remote controller, the touch remote controller necessarily generates position change at the moment, and the probability is that a user needs to operate the remote-controlled equipment when picking up the touch remote controller, at the moment, the backlight control system is started to assist in realizing touch control, so that the problem that the equipment is not changed according to the intention of the user due to the fact that the user touches the touch key by mistake can be effectively solved.
Referring to fig. 5, fig. 5 is a schematic structural diagram of a touch remote control in a hardware operating environment according to an embodiment of the present invention.
As shown in fig. 5, the touch remote controller may further include: a processor 1001, such as a Central Processing Unit (CPU), a communication bus 1002, a user interface 1003, a network interface 1004, and a memory 1005. The communication bus 1002 is used to implement connection communication among these components. The user interface 1003 may include a Display (Display), an input unit such as a Keyboard (Keyboard), and the optional user interface 1003 may also include a standard wired interface, a wireless interface. The network interface 1004 may optionally include a standard wired interface, a WIreless interface (e.g., a WIreless-FIdelity (WI-FI) interface). The Memory 1005 may be a Random Access Memory (RAM) Memory, or a Non-Volatile Memory (NVM), such as a disk Memory. The memory 1005 may alternatively be a memory device separate from the processor 1001 described above.
Those skilled in the art will appreciate that the configuration shown in FIG. 5 is not intended to be limiting of touch remotes and may include more or fewer components than those shown, or some components may be combined, or a different arrangement of components.
As shown in fig. 5, the memory 1005, which is a storage medium, may include therein an operating system, a data storage module, a network communication module, a user interface module, and a backlight control program.
In the touch remote controller shown in fig. 5, the network interface 1004 is mainly used for data communication with other devices; the user interface 1003 is mainly used for data interaction with a user; the processor 1001 and the memory 1005 of the touch remote controller of the present invention may be disposed in the touch remote controller, and the touch remote controller calls the backlight control program stored in the memory 1005 through the processor 1001 and executes the backlight control method provided by the embodiment of the present invention.
An embodiment of the present invention provides a backlight control method, which is applied to the backlight control system and a touch remote controller including the backlight control system, and referring to fig. 6, fig. 6 is a flowchart illustrating an embodiment of a backlight control method according to the present invention.
In this embodiment, the backlight control method includes:
step S10, when the motion detection module detects that the motion state of the touch remote controller changes, the backlight of the switch key position in the touch panel is turned on;
step S20, acquiring touch information of the current interactive object from the touch remote controller;
step S30, turning off the backlight at the switch key position according to the touch information, reducing the driving current intensity, and turning on the backlight of the touch panel;
step S40, acquiring the current key position according to the touch information, and generating light control information according to the current key position;
step S50, turning off the backlight of the touch panel according to the light control information, increasing the driving current intensity, and turning on the backlight of the current key position.
It should be noted that, in this embodiment, the execution subject is a touch remote controller, and a current interaction object of the touch remote controller is a user who is currently using the touch remote controller. The motion detection module comprises a gyroscope and an accelerometer, the gyroscope can accurately detect the angle change of the touch remote controller in the horizontal direction and the vertical direction, the accelerometer can accurately detect the speed change of the touch remote controller, the accelerometer and the touch remote controller can both reflect the change of the motion state of the touch remote controller, the probability is that a user needs to operate a remote-controlled device when picking up the touch remote controller, and the backlight is turned on through a backlight control system to assist in realizing touch control.
As an example, in this embodiment, the step of turning on the backlight of the switch key position in the touch panel in step S10 includes: and setting the light color of the light source to be a first preset light color, and turning on the light source corresponding to the position of the switch key in the touch panel.
It should be noted that the first preset light color is red, and the corresponding RGB value is (255,0,0), which is used to remind the user of the position of the power on/off key. For convenience of explanation, the present embodiment is explained by using fig. 3 in the above-mentioned embodiment of the backlight control system.
It can be understood that, in general, the power on/off button of the remote controller is designed at the upper left corner, i.e., (x1, yj). When a user takes up the remote controller, the gyroscope detects that the angle of the remote controller changes, the accelerometer detects that the position and the speed of the remote controller change, at the moment, a system chip of the remote controller considers that the user needs to use the remote controller, and at the moment, the drivers respectively use electricityStream I X ,I Y Driving X 1 And Y J Both LEDs are red, (x1, yj) the red light in this position will be brighter than the other areas to prompt the user whether to turn on.
As an example, in the present embodiment, the step of turning on the backlight of the touch panel in step S30 includes: and setting the light color of the light source to be a second preset light color, and turning on all the light sources in the backlight matrix.
It should be noted that the second preset light color is blue, and the corresponding RGB value is (0, 255), which is used for displaying the positions of all the keys for the user to prompt the user to continue the operation.
It can be understood that, after the user starts up by pressing the power on/off key, for the user to use conveniently and make the user operate all keys of the remote controller more conveniently, at this time, the user needs to touch the touch panel of the remote controller to display the whole key area uniformly, and in order not to affect the user to use and be compatible with the whole power consumption, at this time, the driving modules are respectively controlled to be 20% I X ,20%I Y The current intensity is driven, and the whole touch area displays a blue light, so that the user is prompted to continue operating, the user experience is not influenced, and the system power consumption is reduced.
As an example, in this embodiment, the step of turning on the backlight of the current key position in step S50 includes: and setting the light color of the light source to be a third preset light color, and turning on the light source corresponding to the current key position.
It should be noted that the third preset light color is green, and the corresponding RGB value is (0, 255), which is used to help the user to confirm the currently touched key position and give the user real-time key feedback.
It can be understood that when a user presses a certain key p (m, n), if m, n are integers, i.e. m is an integer belonging to {1,2, …, K }, and n is an integer belonging to {1,2,3, …, J }, the key p can be considered as an X, Y intersection position (i.e. the key p is both a horizontal standard key and a vertical standard key), and the driving module drives the key p with a current I X ,I Y Driving the corresponding Xm, Yn to light up the green light, namely, the key is changed from blue to green,the user can perceive that the touched key is executed by the system, and the operation is successful. When m is an integer and n is not an integer, i.e.
Figure RE-GDA0003725259940000111
The point P is positioned between two LEDs in the Y direction (namely, the button P is a transverse non-standard button and a longitudinal standard button), at the moment, Xm is lightened in the X direction of the system, Yn +1/2 and Yn-1/2 are lightened in the Y direction, and at the moment, the brightness of the button is obviously higher than that of other areas; also, when m is not an integer, and n is an integer,
Figure RE-GDA0003725259940000112
(i.e., the key p is both a horizontal standard key and a vertical non-standard key), at this time, the system X direction lights Xm +1/2, Xm-1/2, and the Y direction lights Yn; when neither m nor n is an integer,
Figure RE-GDA0003725259940000113
(i.e., key p is both a landscape non-standard key and a portrait non-standard key) at which time the system lights Xm +1/2, Xm-1/2, Yn +1/2 and Yn-1/2. When the remote controller is not used for a certain time, the system can automatically extinguish the backlight to reduce the power consumption, and if a user wants to continue operating the remote controller at the moment, the user can wake up the remote controller only by touching the touch panel once again. In addition, due to the existence of the gyroscope and the accelerometer, when a user accidentally touches the touch panel without using the remote controller at ordinary times, the remote controller cannot be awakened due to the limitation of detection factors such as the angle and the position of the remote controller, so that the risk of mistakenly triggering the remote controller is avoided, and the user experience is enhanced.
As an example, in the present embodiment, step S20 is followed by: and if the touch information is not received within the preset time length and the change of the motion state of the touch remote controller is not detected, closing the backlight of the switch key position.
It can be understood that preset duration is the time of waiting for user operation, preset duration can set up to reasonable numerical value such as 5 seconds, 8 seconds, 15 seconds, 30 seconds or 1 minute, considers the power consumption problem, if the user does not have the operation for a long time after picking up the remote controller or the user puts down the remote controller after picking up the remote controller, then need not to open button light all the time to avoid causing unnecessary waste.
The embodiment provides a backlight control method, which overcomes the problems of power consumption waste and influence on user experience of the existing touch remote controller. The backlight control method is realized based on the touch remote controller and the backlight control system, and because the motion detection module electrically connected with the backlight control system is added in the touch remote controller, the motion detection module comprises a gyroscope and an accelerometer, the angle change of the horizontal direction and the vertical direction of the touch remote controller can be accurately detected through the gyroscope, the speed change of the touch remote controller can be accurately detected through the accelerometer, the motion state of the touch remote controller can be reflected to change, the situation that the touch remote controller needs to be operated by a user is picked up by the user at the moment, the backlight control system is turned on again to assist in realizing touch control, and therefore the problem that the equipment is not intended to change due to the fact that the user touches a touch key by mistake can be effectively avoided. Furthermore, because the backlight control system adopts the RGB LED lamp effect matrix as the backlight matrix, the number of the RGB LED backlight sources is set by referring to the number of the keys in the rows and the columns in the key matrix, namely, each row or each column only corresponds to one backlight source, and the light emitted by the backlight sources in the rows and the columns is uniformly guided to the whole plane by using the light guide plate. When a touch event occurs, the backlight source only turns on the backlight source corresponding to the touch area, and the whole backlight is not lighted. On one hand, the method can be conveniently used normally by a user in a dark scene, and can confirm that the operation of the user is executed. On the other hand, only the light source in the corresponding area is lightened, so that the power consumption can be effectively reduced, and the service life of the battery is further prolonged. In the backlight control method of the embodiment, a plurality of specific application scenes using the touch remote controller are provided, and the light with different colors and brightness is used for prompting different situations of using the remote controller by a user, so that the user can be given instant touch feedback, and the use experience of the user is effectively improved.
In addition, an embodiment of the present invention further provides a computer-readable storage medium, where the computer-readable storage medium may be disposed in the backlight control system and the touch remote controller in the foregoing embodiments, and a backlight control program is stored on the computer-readable storage medium, and when executed by a processor, the backlight control program implements the backlight control method provided in the embodiment of the present invention.
