detailed description

In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

FIG. 2 is a schematic front view of a mobile terminal according to an embodiment of the present invention. As shown in FIG. 2 , the mobile terminal includes a display screen 10 and a cover 20 . In addition, the mobile terminal also includes a control circuit, at least one key display component and at least one touch component. The button display component is arranged under the cover plate, and a touch component corresponding to a button display component is arranged under the cover plate. The control circuit is, for example, a CPU, which is connected to the display screen, the key display component and the touch control component, and controls each of the key display components to display a function key icon matching the display interface of the current display screen, And process the touch signal triggered by the touch component corresponding to any one of the function button icons touched by the user. The above-mentioned control circuit, key display component and touch control component are not shown in the figure.

In an embodiment of the present invention, the key display component may include an LED dot matrix, that is, the control circuit drives a plurality of LEDs in the LED dot matrix to turn on and off to control the key display component to display the function key icon, For example, a home key (home key) icon, a menu key icon, a return key icon, an accelerator key icon in a game state, a deceleration key icon, a left turn key icon, and a right turn key icon.

The button display assembly proposed in the embodiment of the present invention may include, for example, an LED dot matrix arranged under the cover plate 20, and a touch control component is arranged on the edge of the dot matrix. The touch control component cooperates with the LED dot matrix to realize the LED dot matrix. function of the function button icon. Or, a transparent touch layer can be set under the cover plate 20, and an LED dot matrix is set under the transparent touch layer, and the LED dot matrix emits light through the touch layer and the cover plate to display the button icon on the cover plate 20. At the same time, corresponding to the LED dot matrix, the control circuit endows the corresponding touch area with a function matching the button icon displayed on the LED dot matrix. For example, when the LED dot matrix is displayed as a menu key, the touch area near or below it is correspondingly set to have the function of a menu key. When the user clicks the button icon displayed on the LED dot matrix, the touch component matching the button icon detects the user's touch and returns the touch signal to the control circuit, thereby realizing the touch recognition of the button icon. Since each touch component is independent of each other and separated by a threshold distance, adjacent touch components will not interfere with each other and cause false triggering.

The key display component provided in the embodiment of the present invention may also include, for example, electronic paper. For example, the touch component can be arranged along the edge of the electronic paper, and is preferably arranged under the electronic paper. The electronic paper can display function button icons that match the display interface of the current display screen, and the touch component below the electronic paper can be controlled by the control circuit to have a touch function that matches the currently displayed function button icons. At the same time, the thickness of the electronic paper is very thin, and the touch component disposed under it can accurately identify the user’s touch without increasing the driving capability of the touch component, which can effectively reduce the power consumption of the touch component.

The cover plate 20 shown in FIG. 2 has an upper region 3 and a lower region 4 . Top area 3 for example can be provided with accelerator key 21, deceleration key 22 under the game state, and lower area 4 can be provided with menu key 23, home page key 24, return key 25 etc. for example, or the position of deceleration key 22 and the position of home page key 24 also can be set. You can set the function of the breathing light, such as displaying missed calls or unread messages.

In an embodiment, when the mobile terminal is in the standby state with a black screen, the positions of the above-mentioned buttons 21-25 may not display patterns, nor configure any functions.

FIG. 3 is a schematic diagram of function button icons displayed on the cover in a game state. As shown in Figure 3, in the game state, the cover plate 20 can display different game button icons, such as a left turn key 31, a right turn key 32, a forward key 33, a backward key 34, an accelerator key 35, a deceleration key 36, and Pause key, Escape key, etc. The number and functions of button icons depend on the current mobile phone space and/or current interface content.

Specifically, when the control circuit in the mobile terminal detects that the mobile terminal is in a game state, the control circuit sets the LED dot matrix corresponding to the button icons 31-36 in FIG. Button icons for back, acceleration, and deceleration, and the touch area corresponding to each LED dot matrix is defined as the corresponding touch function of left turn, right turn, forward, backward, acceleration, and deceleration. The setting of the LED dot matrix pattern and the corresponding touch area by the control circuit can be realized through a program, and the program can be embedded in a corresponding game, for example. When entering the game state, the program commands the control circuit to control the LED dot matrix to display the corresponding key icon, and at the same time assigns the corresponding touch function to the touch component corresponding to each LED dot matrix, so as to realize the button with variable icon and function icon.

Through such setting, when the user is playing games, different game function buttons can be displayed on the cover plate 20, which is convenient for the user to control; It eliminates false touches and maintains the aesthetic unity of the appearance of the mobile phone.

FIG. 4 is a schematic diagram of function button icons on the cover plate in a vertical video screen state. As shown in FIG. 4 , in the video state, function key icons such as a menu key 41 , a home key 42 , and a return key 43 may be displayed in the lower area 40 . Through the above settings, when the mobile terminal is playing video, the most commonly used function button icons can be displayed on the cover 20, avoiding unnecessary buttons occupying the space of the cover, and also avoiding the display of virtual button icons on the display screen that will block the user problem of sight.

In the above several embodiments, in addition to the above-mentioned display screen, cover plate, control circuit, key display component and touch control component corresponding to the key display component, the mobile terminal may further include a memory. Stored in the memory is the state information of the lighting and extinguishing of the plurality of LED dot matrixes when each function key icon is displayed, and when at least one function key icon needs to be displayed, the control circuit extracts from the memory the information corresponding to the function. The status information of the button icon, and control the lighting and extinguishing of each LED in the LED dot matrix corresponding to the function button icon according to the status information.

For example, register values corresponding to video states can be stored in the memory. When the mobile terminal enters the video state, the control circuit can control each button assembly to display button icons corresponding to the video state according to the registered value, for example, button icons such as progress, volume or brightness adjustment bar can be displayed.

Likewise, for example, a register value corresponding to a game state can be stored in a memory. When the mobile terminal enters the game state, the control circuit can control each button component to display the button icon corresponding to the game state according to the registered value, for example, it can display left turn, right turn, forward, backward, acceleration, deceleration, pause, exit Etc.; in normal state, it can display home button, menu button, return button and other button icons.

Likewise, for example, register values corresponding to the landscape and portrait states can be stored in the memory. That is, the registered value includes a first registered value corresponding to the horizontal screen state and a second registered value corresponding to the vertical screen state, and when in the horizontal screen state, the control circuit controls each of the key display components according to the first registered value Displaying horizontal button icons; when in a vertical screen state, the control circuit controls each of the button display components to display vertical button icons according to the second registered value.

For example, FIG. 5A and FIG. 5B are schematic diagrams of the mobile terminal displaying function button icons in the vertical screen state and the horizontal screen state, respectively. Comparing Fig. 5A and Fig. 5B, it can be seen that the directions of buttons 51-53 are switched with the state of landscape and portrait. Patterns are always positive.

In this embodiment, the horizontal screen state or the vertical screen state of the mobile terminal can be judged by the built-in gyroscope. For example, the gyroscope can return different data according to the horizontal screen or vertical screen state of the mobile terminal. The data correspondingly controls each LED dot matrix to display different icons, and assigns different functions to the corresponding touch areas. For example, when the gyroscope determines that the mobile terminal is in the vertical screen state shown in FIG. 5A, it can return the data A1 to the control circuit, and the control circuit controls the buttons 51-53 to display the vertical menu key 51 and the home page key 52 respectively. and the return key 53; when the gyroscope judges that the mobile terminal is in the horizontal screen state shown in Figure 5B, the data A2 can be returned to the control circuit, and the control circuit controls the buttons 51-53 to display respectively horizontal menu keys 51 and home page keys 52 accordingly And return key 53, so that the user watches. In addition to the gyroscope, the gravity sensor can also be used to detect the horizontal and vertical screen status of the display screen.

Preferably, the data of the above-mentioned control command for triggering the control circuit can be stored in the memory, and the built-in program of the mobile terminal scans the memory at intervals, and when it is detected that the data of the trigger control command of the memory changes, then according to the current The state redefines the content displayed by the button display component and the function of the touch component.

Through the above settings, the direction of the buttons 51-53 is switched with the horizontal screen and the vertical screen. When the direction of the mobile phone display screen changes, the direction of the function buttons 51-53 changes accordingly, so as to ensure that the patterns seen by the user are always positive. .

For another example, for example, register values corresponding to the left-hand holding state and the right-hand holding state can be stored in the memory. In the case that there are multiple key display components, the registered values include the third registered value corresponding to the right-handed state and the fourth registered value corresponding to the left-handed state. When the control circuit detects that the memory There is a third registered value in the memory, and the control circuit controls the plurality of key display components to display sequentially arranged key icons according to the third registered value; when the control circuit detects that there is a fourth registered value in the memory The control circuit controls the plurality of key display components to display key icons arranged in reverse order according to the fourth registered value.

For example, FIG. 6A and FIG. 6B are schematic diagrams showing function button icons in the right-hand holding and left-hand holding states of the mobile terminal. As shown in Figure 6A and Figure 6B, the buttons 61-63 and functions in the mobile terminal (such as a mobile phone) will be switched along with the switching of the left and right hands, for example: when the right hand as shown in Figure 6A holds the mobile terminal, The return key 63 is in the lower right corner of the mobile terminal, and the menu key 61 is in the lower left corner. When holding the mobile terminal with the left hand as shown in FIG. 6B , the return key 63 is in the lower left corner of the mobile terminal, and the menu key 61 is in the lower right corner.

In an embodiment, it can be determined whether the left hand or the right hand is held according to the holding positions of the thumb and the other four fingers. For example, a right-handed grip typically has the thumb on the right side of the display and the rest of the fingers on the left side of the display. When the control circuit detects that there is only one contact point on the right side of the mobile terminal and more than one contact point on the left side, it can be judged that the user is using the right hand to hold the mobile terminal, and the data A3 can be returned to the control circuit, and the control circuit controls the buttons 61- 63 are respectively displayed as menu key, home key and return key from left to right; when the control circuit detects that there is only one contact point on the left side of the mobile terminal and more than one contact point on the right side, it can be judged that the user is using the left hand to hold , the data A4 can be returned to the control circuit, and the control circuit controls the keys 61-63 to be displayed as a return key, a home key and a menu key respectively from left to right.

Through the above settings, the direction of the keys 61-63 is switched along with the left and right holding states and the right hand holding state, for example, in the forward direction "menu key, home key and return key" and in the reverse direction "return key, home key and menu key" "Switch between the two orders. When the hand of the user holding the mobile terminal changes, the arrangement direction of the function keys 61-63 changes accordingly, so as to facilitate the user's operation.
