Detailed Description
It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
Referring to fig. 1, fig. 1 is a schematic diagram of a backlight control system according to an embodiment of the invention.
In this embodiment, the backlight control system includes:
A touch panel 100, the touch panel 100 for receiving touch information;
a key matrix 101, wherein the key matrix 101 is arranged on the back side of the touch panel, and the key matrix comprises a plurality of transverse key groups and longitudinal key groups;
The backlight matrix 200, wherein the backlight matrix 200 comprises a transverse light guide sheet, a longitudinal light guide sheet and a light source, the transverse light guide sheet and the longitudinal light guide sheet are respectively arranged at one side of the transverse key group and one side of the longitudinal key group, which are 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;
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 with the backlight matrix 200;
a system chip 400, wherein the system chip 400 is electrically connected with the touch panel 100 and the driving module 300 respectively;
When the touch panel 100 receives the 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 will be appreciated that the touch panel 100 is an important component of a backlight control System, and is configured to receive information touched by a user and transmit the information to a System On Chip (SOC) 400 for processing; as can be seen from the light emitting direction marked in fig. 1, the back side of the touch panel refers to the side of the touch panel that is not touched by the user, and the key matrix 101 includes a plurality of touch keys, where the keys form a plurality of transverse key groups and longitudinal key groups, and the embodiment is described based on a plane, where the transverse direction refers to the horizontal direction and the longitudinal direction refers to the vertical direction, which is only for describing the relative positional relationship of the keys in the clear key matrix, and does not represent that the keys must be arranged transversely or longitudinally; the system chip 400 communicates with the driving module 300 through an I2C (Inter-INTEGRATED CIRCUIT, two-wire serial bus) protocol, and through system setting, the backlight matrix 200 can be controlled to emit light with different brightness according to the use scene of a user, and the on and off of the LEDs can be controlled independently; the driving module 300 provides driving current to the backlight matrix 200 to control the brightness of the LEDs in the backlight matrix, and in this embodiment, assuming that the horizontal direction is X and the vertical direction is Y, the rated currents of the LEDs are I X,IY (since the length and width of most of the key matrices 101 are different, in order to make the brightness in the horizontal and vertical directions as uniform as possible, I X is slightly larger than I Y). In addition, the embodiment further includes a power supply module electrically connected to the system chip 400 and used for supplying power to the whole system, and a bluetooth module electrically connected to the system chip 400 and used as a connecting link between the backlight control system and the external controlled device, where the bluetooth module is used for transmitting 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 a structure or a module having an electrical connection relationship, and is capable of transmitting electrical signals and communication signals.
It should be noted that, the backlight matrix in this embodiment is an RGB LED light-efficient matrix, and is composed of a horizontal light guide sheet, a vertical light guide sheet, and light sources at the ends of the horizontal light guide sheet and the vertical light guide sheet, where the light sources are all RGB LED lamps, instead of the conventional white LED. For the convenience of description, the total number of keys is close to j×k if the number of keys is j×k, and if the conventional design thought is adopted, the backlight of each key needs to be controlled independently by the same number of LED backlights, that is, the number of backlights is consistent with the number of keys in the conventional backlight matrix. In this embodiment, only one RGB LED backlight source is required to be disposed at each column and each row, so only j+k backlight sources are required.
As an example, in this embodiment, the lateral key group includes a lateral standard key, and the longitudinal key group includes a longitudinal 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 appreciated that in this embodiment, the RGB LEDs are uniformly distributed on both sides of the light guide sheet, so as to divide the light guide sheet into a plurality of light guide areas. Referring to fig. 3, fig. 3 is a schematic diagram of the position distribution of the backlight matrix and the key matrix in the present embodiment, where the grid lines in fig. 3 represent the light guiding paths of the light guiding sheets, the light color points located in the middle area of the grid are key positions, the dark color points located at the left edge and the lower edge of the grid are light source positions, and the lateral light guiding sheets and the lateral standard keys are overlapped when viewed along the light emitting direction, the longitudinal light guiding sheets and the longitudinal standard keys are overlapped, and are horizontally arranged in rows and longitudinally arranged, the lower side light source is the light source at the end of the longitudinal light guiding sheet, and the left side light source is the light source at the end of the lateral light guiding sheet. In fig. 3, the lower left corner is defined as the origin of coordinates, the horizontal direction is defined as the X direction, then the 4 LEDs in the X direction are respectively defined as X 1,X2,…,XK from left to right, the coordinates are respectively defined as (X1, 0), (X2, 0), …, (xk, 0), and similarly, the vertical direction is defined as the Y direction, then the 18 lamps in the Y direction are defined as Y 1,Y2,…,YJ from bottom to top, the coordinates are respectively defined as (0, Y1), (0, Y2) … (0, yj), the LEDs in the X direction respectively illuminate the Y area in the vertical direction corresponding to each LED, that is, when the X 1 is turned on, the light path in the first row of keys is illuminated, and the LEDs in the Y direction respectively illuminate the X area in the vertical direction corresponding to each LED, that is, when the Y 1 is turned on. The touch key can be placed in the whole light guiding area, and in order to better present the light guiding effect, the touch key is generally disposed at the intersection point portion of the LEDs at two sides (i.e. the intersection of the grid lines in fig. 3) as much as possible, and the touch key disposed at the position is a horizontal standard key or a vertical standard key, and the brightness is higher due to the superposition of the brightness.
It should be noted that, the horizontal standard key corresponds to the horizontal light guide sheet and the light source located in the Y direction, and the vertical standard key corresponds to the vertical light guide sheet and the light source located in the X direction, and the light source in this embodiment has the same meaning as the backlight source.
As an example, in this embodiment, the lateral key group further includes a lateral non-standard key, and the longitudinal key group further includes a longitudinal non-standard key; the transverse nonstandard keys are located between the light emitting directions of the transverse light guide sheets, and the longitudinal nonstandard keys are located between the light emitting directions of the longitudinal light guide sheets.
It will be appreciated that the hardware device including the backlight control system shown in fig. 2 generally has a circular control area, such as up, down, left, right and confirmation keys, and it is impossible to set all keys to the light path intersections in order to ensure the overall symmetry and the aesthetic appearance of the device during the design process, so in order to ensure the backlight effect, in this embodiment, such keys are set at the middle positions of two light sources in the X direction or the Y direction (although only the keys set at the middle positions of two light sources in the X direction are shown in fig. 3, they do not represent the non-standard keys set at the middle positions of two light sources in the Y direction), and the keys set at such positions are non-standard keys in either direction or both directions. It will be appreciated 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 transverse standard keys and longitudinal standard keys), may correspond to two light sources in the X direction and one light source in the Y direction (both transverse standard keys and longitudinal non-standard keys), may correspond to one light source in the X direction and two light sources in the Y direction (both transverse non-standard keys and longitudinal standard keys), and may correspond to two light sources in the X direction and two light sources in the Y direction (both transverse non-standard keys and longitudinal non-standard keys).
In this embodiment, a backlight control system is provided, where an RGB LED light effect matrix is used as a backlight matrix, the number of RGB LED backlights is set with reference to the number of keys of rows and columns in the key matrix, that is, each row or each column corresponds to only one backlight, and light emitted by the backlights of the rows and columns is uniformly guided to the entire plane by using a light guide plate. When a touch event occurs, the backlight will only turn on the backlight corresponding to the touch area, but will not illuminate the entire backlight, and in addition, the embodiment will adjust the backlight color as a response of the user touch according to the specific operation of the user. On the one hand, the method can be convenient for users to use normally in dim scenes, and can confirm that the operation of the users is executed. On the other hand, only the light source in the corresponding area is lighted, so that the power consumption can be effectively reduced, and the service life of the battery is 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, where 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 for acquiring a position change of the touch remote controller 10, for example, a gyroscope (gyroscillope), which in this embodiment may be a piezoelectric gyroscope, a micromechanical gyroscope, a fiber optic gyroscope, or a laser gyroscope; the motion detection module 500 further includes an acceleration sensor, such as an accelerometer (accelerometer), for obtaining the motion state of the touch remote control, which in this embodiment may be a linear accelerometer or a pendulum accelerometer.
In this embodiment, a motion detection module electrically connected to a backlight control system is added to the touch remote controller, where the motion detection module includes a gyroscope and an accelerometer, and can accurately detect angular changes in a horizontal direction and a vertical direction of the touch remote controller through the gyroscope, and can accurately detect speed changes of the touch remote controller through the accelerometer, both of which can reflect changes in a motion state of the touch remote controller, and at this moment, the touch remote controller inevitably generates position changes, which is a situation that a user needs to operate a remote controlled device when picking up the touch remote controller, and at this moment, the backlight control system is started again to assist in realizing touch control, so that a problem that a device is changed due to a user's mistaken touch of a touch key is effectively avoided.
Referring to fig. 5, fig. 5 is a schematic structural diagram of a touch remote controller of a hardware running 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 (Central Processing Unit, CPU), a communication bus 1002, a user interface 1003, a network interface 1004, a memory 1005. Wherein the communication bus 1002 is used to enable connected communication between these components. The user interface 1003 may include a Display, an input unit such as a Keyboard (Keyboard), and the optional user interface 1003 may further 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 high-speed random access Memory (Random Access Memory, RAM) Memory or a stable Non-Volatile Memory (NVM), such as a disk Memory. The memory 1005 may also optionally be a storage device separate from the processor 1001 described above.
It will be appreciated by those skilled in the art that the structure shown in fig. 5 is not limiting and may include more or fewer components than shown, or may combine certain components, or a different arrangement of components.
As shown in fig. 5, an operating system, a data storage module, a network communication module, a user interface module, and a backlight control program may be included in the memory 1005 as one type of storage medium.
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 in the touch remote controller of the present invention may be disposed in the touch remote controller, and the touch remote controller invokes 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.
The embodiment of the invention provides a backlight control method, which is applied to the backlight control system and a touch remote controller comprising the backlight control system, and referring to fig. 6, fig. 6 is a flow chart of an embodiment of the backlight control method of the 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, a backlight of a switch key position in the touch panel is turned on;
Step S20, touch information of a current interaction object from the touch remote controller is obtained;
step S30, turning off the backlight of 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;
And 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 body is a touch remote controller, and the current interaction object of the touch remote controller is the user who is currently using the touch remote controller. Because the motion detection module comprises a gyroscope and an accelerometer, the gyroscope can accurately detect the angle change of the horizontal direction and the vertical direction of the touch remote controller, the accelerometer can accurately detect the speed change of the touch remote controller, both can reflect the change of the motion state of the touch remote controller, and the high probability is that a user needs to operate the remote controlled equipment when picking up the touch remote controller, and the touch control can be assisted by opening the backlight through the backlight control system.
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 lamp color of the light source as a first preset lamp color, and turning on the light source corresponding to the switch key position in the touch panel.
It should be noted that, the first preset light color is red, and the corresponding RGB value is (255, 0), which is used for reminding the user of the position of the on-off key. For convenience of explanation, this embodiment will be explained with reference to fig. 3 in the above-described embodiment of the backlight control system.
It will be appreciated that the on-off key of the remote control is typically designed to be in the upper left corner, i.e., (x 1, yj) position. When a user picks 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, the system chip of the remote controller considers that the user needs to use the remote controller, at the moment, the driver drives the X 1 LED and the Y J LED to light red lamps respectively by current I X,IY, and the red lamps at the position (X1, yj) are brighter than other areas, so that the user is prompted whether to start up or not.
As an example, in the present embodiment, the step of turning on the backlight of the touch panel in step S30 includes: setting the lamp color of the light source to be a second preset lamp 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 (0,0,255), which is used for displaying the positions of all the keys for the user, so as to prompt the user to continue to operate.
It can be understood that after the user starts up by pressing the on-off key, in order to facilitate the use of the user and make the user operate all keys of the remote controller more conveniently, the user needs to touch the touch panel of the remote controller to uniformly display the whole key area, so as not to affect the use of the user and the compatibility of the whole power consumption, at this time, the driving module drives with the current intensity of 20% I X,20％IY respectively, and makes the whole touch area display blue lights, namely, prompts the user to continue to operate, meanwhile, the user experience is not affected, 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 lamp color of the light source to be a third preset lamp color, and turning on the corresponding light source of the current key position.
It should be noted that, the third preset light color is green, and the corresponding RGB value is (0,0,255), which is used to help the user confirm the current touched key position and give the user real-time key feedback.
It will be appreciated that when a user presses a certain key p (m, n), if m, n are integers, that is, m e {1,2, …, K }, n e {1,2,3, …, J }, the key p can be considered as the position of the crossing point of X, Y (that is, the key p is not only a horizontal standard key but also a vertical standard key), the driving module drives the corresponding Xm, yn to turn green with the current I X,IY, that is, the key turns green from blue, so that the user perceives that the touched key has been executed by the system, and the operation is successful. When m is an integer and n is not an integer, i.eThe P point is positioned between two LEDs in the Y direction (namely, the key P is not a transverse standard key and is a longitudinal standard key), at the moment, the system is lightened in the X direction by Xm, yn+1/2 and Yn-1/2 are lightened in the Y direction, and at the moment, the brightness of the key is obviously higher than that of other areas; also, when m is not an integer, n is an integer,(I.e., key p is both a horizontal standard key and a vertical non-standard key), at this time, the system is lighted in the X direction by Xm+1/2, xm-1/2, and Y direction by Yn; when m, n are not integers,(I.e., key p is neither a horizontal nor a vertical non-standard key), at which point 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 turn off the backlight to reduce the power consumption, and if the user wants to continue operating the remote controller at the moment, the user only needs to touch the touch panel once again to wake up the remote controller. In addition, due to the existence of the gyroscope and the accelerometer, when a user touches the touch panel accidentally without using the remote controller at ordinary times, the user cannot wake up the remote controller due to the limitation of detection factors such as angles, positions and the like, so that the risk of false triggering of the remote controller is avoided, and the user experience is enhanced.
As an example, in this embodiment, step S20 further includes: and if the touch information is not received within the preset time period and the change of the motion state of the touch remote controller is not detected, turning off the backlight of the switch key position.
It can be understood that the preset duration is a time waiting for the operation of the user, and the preset duration can be set to be a reasonable value of 5 seconds, 8 seconds, 15 seconds, 30 seconds or 1 minute, etc., and in consideration of the power consumption problem, if the user does not operate for a long time after picking up the remote controller or puts down the remote controller after picking up the remote controller, the key light is not required to be turned on all the time, so that unnecessary waste is avoided.
In the embodiment, a backlight control method is provided, and the problems of power consumption waste and influence on the use experience of a user in the conventional touch remote controller are solved. 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 angular changes of the horizontal direction and the vertical direction of the touch remote controller can be accurately detected through the gyroscope, the speed changes of the touch remote controller can be accurately detected through the accelerometer, the two can reflect the change of the motion state of the touch remote controller, at the moment, the high probability is that a user takes up the touch remote controller and needs to operate the remote controlled equipment, at the moment, the backlight control system is started again to assist in realizing the touch control, and therefore the problem that the equipment is not willing to change due to the fact that the user mistakenly touches a touch key can be effectively avoided. Furthermore, the backlight control system adopts the RGB LED lamp effect matrix as the backlight matrix, the quantity of RGB LED backlight sources is set according to the key quantity of rows and columns in the key matrix, namely, each row or each column corresponds to only one backlight source, and the light emitted by the backlight sources of 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 will only turn on the backlight corresponding to the touch area, but will not illuminate the entire backlight, and in addition, the embodiment will adjust the backlight color as a response of the user touch according to the specific operation of the user. On the one hand, the method can be convenient for users to use normally in dim scenes, and can confirm that the operation of the users is executed. On the other hand, only the light source in the corresponding area is lighted, so that the power consumption can be effectively reduced, and the service life of the battery is prolonged. In the backlight control method of the embodiment, various specific application scenes using the touch remote controller are provided, the user is prompted to use the lamplight with different colors and brightness under different situations of using the remote controller, instant touch feedback can be given to the user, and further the use experience of the user is effectively improved.
In addition, the embodiment of the invention also provides a computer readable storage medium, which can be arranged in the backlight control system and the touch remote controller in the above embodiments, and the computer readable storage medium stores a backlight control program, and when the backlight control program is executed by a processor, the backlight control method provided by the embodiment of the invention is realized.
