Referring to fig. 1A to 1E, when the main screen 130 moves along the horizontal direction PD relative to the base 110, the bracket assembly 120 is correspondingly switched to an extension mode (see fig. 1D and 1E) or a bending mode (see fig. 1A and 1C), and the vertical distance VD between the first sensor 150 and the plane BS changes, so as to detect the orientation of the main screen 130 and transmit a first signal to the cpu 140, and to control the sub-screen 160 to extend out of the main screen 130 in a multi-stage manner, and the display area DA of the main screen 130 can be divided into a plurality of equal parts in the extension mode or combined into one equal part in the bending mode.
Fig. 2A to 2C are schematic front plan views illustrating the sub-screen of fig. 1A switched to an information mode, a touch mode, or an input mode. Fig. 3 is a flow chart of sub-screen switching of fig. 2A to 2C.
Referring to fig. 1C and fig. 2A to 2C, the sub-screen 160 has an actuator 161 (e.g., a driving motor) electrically coupled to the cpu 140, and after the cpu 140 determines the first signal returned by the first sensor 150, the actuator 161 starts to operate and drives the sub-screen 160 to extend out of the main screen 130 in a multi-stage manner, so as to switch the sub-screen 160 into an information mode (see fig. 2A), a touch mode (see fig. 2B) or an input mode (see fig. 2C).
Additionally, the message mode is that the sub-screen 160 is extended at least a portion of the way out of the main screen 130, which is used to display simple messages, such as weather temperature, date, etc. The touch mode is that two thirds of the sub-screen 160 extends out of the main screen 130, and in this mode, the sub-screen 160 opens the touch function to replace an external mouse, so that the user can control the mouse in the display area DA of the main screen 130 with both hands. In the input mode, the sub-screen 160 extends out of the main screen 130, and in this mode, the sub-screen 160 displays a virtual keyboard and retains a touch area, and has the input functions of a keyboard and a mouse, so that a user can input a desired command through the virtual keyboard displayed on the sub-screen 160.
In detail, the main screen 130 has a microcontroller 131 electrically coupled to the cpu 140 and the first sensor 150, respectively. In practical use, a first signal (e.g., an analog signal) of the first sensor 150 is transmitted to the microcontroller 131, and is converted into a corresponding first digital signal to be transmitted to the cpu 140, and the first signal is determined by the cpu 140 and then automatically transmits a corresponding command to the microcontroller 131 to trigger or stop the actuator 161.
The display 100 further includes a second sensor 170 disposed on the sub-screen 160 and electrically coupled to the microcontroller 131, wherein a second signal (e.g., an analog signal) of the second sensor 170 is transmitted to the microcontroller 131 and converted into a corresponding second digital signal to be transmitted to the cpu 140, and the second signal is determined by the cpu 140 and then automatically transmits a corresponding command to the microcontroller 131 to trigger or stop the actuator 161.
In the present embodiment, the first sensor 150 and the second sensor 170 are pressure sensors, optical sensors, accelerometers, or buttons.
Briefly described, the pressure sensor is used to sense an external force, such as a manual pressure or a pressure against a flat surface, and when the pressure value meets a predetermined value, the microcontroller activates the actuator and drives the sub-screen. When the external force disappears, the microcontroller starts the actuator and drives the auxiliary screen to return to the initial state.
The light sensor is used for sensing the intensity of light reflection, when the light sensor is closer to the plane, the obtained light intensity is higher, and when the light intensity accords with a preset value (namely, the main screen is closer to the plane), the microcontroller starts the actuator and drives the auxiliary screen. When the light sensor is far away from the plane and the light intensity is lower than the preset value, the actuator reversely drives the auxiliary screen to return to the initial state.
The accelerometer is used for sensing the acceleration value of three axial to accurately learn the position of main screen, when the acceleration value of three axial accords with the default (main screen is more nearly the plane or is more close to the user promptly), microcontroller will start the actuator and drive vice screen. When the accelerometer returns to the original position, the actuator reversely drives the auxiliary screen to return to the initial state.
The button depends on the manual pressing to output a starting signal, so that the actuator drives the auxiliary screen. And pressing the unlocking button once again to enable the actuator to reversely drive the auxiliary screen to return to the initial state.
The following describes the switching process of the display 100 according to the present invention.
Please refer to fig. 1A to fig. 1C and fig. 3. When the bracket assembly 120 is switched to the bending mode (i.e., away from the user), an acute angle G1 is formed between the first link 121 and the second link 122, and the second link 122 and the main screen 130 are located above the base 110. In the bending mode of the stand assembly 120, the main screen 130 moves in the horizontal direction PD to be located above the base 110, and at this time, the first sensor 150 synchronously detects the vertical height VD of the main screen 130 relative to the plane BS (for example, using a light sensor), and at this moment, the vertical height VD is higher than a preset value (i.e., the received light intensity is less than the preset value). The cpu 140 transmits a corresponding command to the microcontroller 131, and the microcontroller 131 triggers the actuator 161 to switch the sub-screen 160 to the initial state, i.e. a small portion of the sub-screen extends out of the main screen 130 (the sub-screen 160 is switched to the information mode), and the display area DA of the main screen 130 is merged into a uniform portion to achieve the purpose of viewing from a long distance.
Please refer to fig. 1C, fig. 1D, fig. 1E and fig. 3. When the stand assembly 120 is switched to the extended mode (i.e. close to the user), an obtuse angle G2 is formed between the first link 121 and the second link 122, and a portion of the first link 121, the second link 122 and the main screen 130 protrudes out of the base 110 along the horizontal direction PD. At this time, the first sensor 150 will synchronously detect the vertical height VD of the main screen 130 relative to the plane BS (for example, an optical sensor is used), and at this moment, the vertical height VD is lower than a preset value (that is, the received light intensity is greater than the preset value), the cpu 140 will transmit a corresponding command to the microcontroller 131, the microcontroller 131 will trigger the actuator 161 to drive the sub-screen 160 to be in an extended state, that is, to be extended outside the main screen 130 (to switch the sub-screen 160 to a touch mode), and in addition, the display area DA of the main screen 130 is suitable for being divided into a plurality of equal parts, so as to achieve the purpose of short-distance multiple display.
Further, the second sensor 170 can be triggered manually or automatically to transmit a second signal to the microcontroller 131, so as to switch the sub-screen 160 from the touch mode to the input mode.
In other embodiments, the display further comprises another optical sensor disposed on a surface of the main screen facing the user for detecting whether the user is present, and when the sensing result is negative, the microcontroller drives the sub-screen to be completely accommodated in the main screen. When the sensing result is yes, the microcontroller drives the auxiliary screen to stretch out of the main screen in a segmented mode.
Based on the above, the display of the invention can be pulled by an external force to correspondingly switch the bracket assembly into the extension mode or the bending mode.
In the extended mode of the stand assembly, the main screen moves relative to the base in the horizontal direction and protrudes out of the base, thereby adjusting the viewing distance between the main screen and the user. Simultaneously, first sensor will synchronous detection main screen for planar vertical height, and continuously transmit first signal to central processing unit, and when the vertical height of first sensor was less than the default or touched the plane, central processing unit can control vice screen multistage formula and stretch out outside main screen to accord with user's demand, in addition, the display area of main screen can be cut apart into a plurality of partitions, reaches the purpose of closely multiple demonstration.
Under the mode of buckling of bracket component, main screen moves and is located the base top along the relative base of horizontal direction, and at this moment, the vertical height of first sensor is higher than the default, and central processing unit can control vice screen and accomodate in main screen or the minority stretches out outside main screen, and in addition, the display area of main screen merges into an aliquot to reach the purpose of long-distance watching.
Furthermore, the display adopts the main screen and the auxiliary screen, the main screen is used for displaying images, and the auxiliary screen has touch control and display functions, so that a user can input instructions, control a mouse and the like through the auxiliary screen, and the pollution caused by residual fingerprints on the main screen can be avoided.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
