Detailed Description
In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1, which is a schematic flow chart of an optical signal output method provided in an embodiment of the present invention, an embodiment of the present invention provides an optical signal output method applied to a wearable device, including the following steps:
step S101, receiving a first optical signal output by each sub-pixel of a screen of the mobile terminal.
Step S102, calculating the intensity of at least one second optical signal except the first optical signal of each sub-pixel according to the intensity of the first optical signal output by each sub-pixel.
Step S103, synthesizing the first optical signal of each sub-pixel and the corresponding at least one second optical signal with the calculated intensity to obtain a third optical signal, and outputting the third optical signal.
In step S101, the color layer of the color filter in the mobile terminal has three colors, red, green, and blue, respectively. Now the color layer of the color filter is changed to a monochrome layer and the corresponding color filter is changed to a monochrome filter. For example, the color of the color layer may be changed to a color of red, and the corresponding monochrome filter may be changed to a red filter. Correspondingly, the color layer of the color filter of the wearable device is changed to a color layer of only blue and green. The monochrome filter in the mobile terminal is set as the red filter, which is just an example, and actually, the monochrome filter in the mobile terminal can also be set as the blue filter or the green filter, and the color layer of the color filter of the corresponding wearable device also changes with the change of the monochrome filter in the mobile terminal. When the monochrome filter in the mobile terminal is set to the blue filter, the color layer of the color filter of the corresponding wearable device is to be changed to the color layers of red and green, and when the monochrome filter in the mobile terminal is set to the green filter, the color layer of the color filter of the corresponding wearable device is to be changed to the color layers of red and blue.
In step S102, in the mobile terminal, a Liquid Crystal Display (LCD) includes an upper polarizer, a lower polarizer, a color filter, and a Liquid Crystal, and the direction of the transmission axis of the upper polarizer and the lower polarizer is 90 degrees, and Liquid Crystal molecules inside the Liquid Crystal can twist the polarization direction of light by 90 degrees without applying a voltage. First, light emitted from the backlight passes through the lower polarizer, and the light is processed into light with the polarization direction consistent with the direction of the transmission axis of the lower polarizer. Each Thin Film Transistor (TFT) corresponds to a red sub-pixel in the monochrome filter, and each TFT also corresponds to a string of liquid crystal molecules in the liquid crystal, and the TFT has a switching function. When an image signal is transmitted, each TFT is controlled, some TFTs may be closed, some TFTs may not be closed, and the opening and closing of each TFT is completely controlled by the image signal.
When a certain TFT is not closed, the arrangement direction of the corresponding string of liquid crystal molecules is not changed, the polarization direction of a beam of light passing through the TFT is twisted by 90 degrees, so that the light passing through the lower polarizer reaches the upper polarizer along the string of liquid crystal molecules, the polarization direction of the light is completely consistent with the penetrating axis direction of the upper polarizer, the beam of light can completely penetrate through the upper polarizer without any loss, and the red light corresponding to the red sub-pixel of the TFT is brightest.
When a TFT is turned on, a voltage is applied to the corresponding liquid crystal molecules to change the alignment direction of the liquid crystal molecules, and the larger the voltage is, the larger the degree of change in the alignment direction of the liquid crystal molecules is, and the smaller the degree of change in the polarization direction of the light is, whereas the smaller the voltage is, the smaller the degree of change in the alignment direction of the liquid crystal molecules is, and the larger the degree of change in the polarization direction of the light is. Thus, when different TFTs are turned on, the voltages applied to the corresponding liquid crystal molecules may be different, which may cause different degrees of change in the arrangement direction of each string of the corresponding liquid crystal molecules, and further cause different degrees of change in the polarization directions of the light propagating along the different strings of the liquid crystal molecules, when the light with the different degrees of change in the polarization directions reaches the upper polarizer, some light may have more light due to the fact that the difference between the polarization direction and the direction of the transmission axis of the upper polarizer, and at this time, the intensity of the light of the sub-pixel corresponding to the TFT is greater, that is, the intensity of the red light of the corresponding sub-pixel is greater, while some light may have less light due to the fact that the difference between the polarization direction and the direction of the transmission axis of the upper polarizer, and at this time, the intensity of the light of the sub-pixel corresponding to the TFT is less, that is, the intensity of the red light of the corresponding sub-pixel point is smaller, so that the intensity of the red light of each sub-pixel point is different. The red light emitted by the screen of the mobile terminal reaches the wearable device, the wearable device calculates the intensity of the corresponding blue light and the green light according to the intensity of the red light of each sub-pixel point, the intensity of the corresponding blue light and the intensity of the corresponding green light which are calculated respectively are different due to the fact that the intensity of the red light of each sub-pixel point is different, and finally the light corresponding to three colors of each sub-pixel point is synthesized, so that a picture with various colors is formed. At the moment, the user can see the content displayed on the screen of the mobile terminal by using the wearable device, while other people cannot see the content displayed on the screen of the mobile terminal at all, and the content displayed on the screen of the mobile terminal can not be stolen by other people as the other people only see the red light which is spread over the whole screen.
Optionally, before the calculating, according to the intensity of the first light signal output by each sub-pixel, the intensity of at least one second light signal of each sub-pixel except the first light signal, the method further includes:
adjusting the gear to a first gear corresponding to first brightness, wherein the brightness of the screen is adjusted to the first brightness, and the first gear corresponds to a first calculation mode;
the calculating the intensity of at least one second light signal except the first light signal of each sub-pixel according to the intensity of the first light signal output by each sub-pixel comprises:
and calculating the intensity of at least one second optical signal except the first optical signal of each sub-pixel in the first calculation mode according to the first calculation mode corresponding to the first gear and the intensity of the first optical signal output by each sub-pixel.
In order to better realize the encryption of the content displayed on the screen of the mobile terminal, different gears can be set, and each gear corresponds to an encryption mode. The mobile terminal and the wearable device are both provided with encryption gears, and the encryption gears of the mobile terminal and the encryption gears of the wearable device are in one-to-one correspondence.
Still taking red light as an example, three levels of red can be defined, pure red, medium red and magenta, respectively, and each of the three levels corresponds to one shift position, for example, pure red corresponds to the first shift position, medium red corresponds to the second shift position, and magenta corresponds to the third shift position. Three gears are arranged on the mobile terminal, and three gears are also arranged on the corresponding wearable equipment. And three gears on the mobile terminal and three gears on the wearable device are in one-to-one correspondence, a first gear on the mobile terminal corresponds to a first gear on the wearable device, a second gear on the mobile terminal corresponds to a second gear on the wearable device, a third gear on the mobile terminal corresponds to a third gear on the wearable device, and each gear has a corresponding calculation mode, for example, when the gear of the mobile terminal is adjusted to be the first gear and the gear of the wearable device is also adjusted to be the first gear, the wearable device can calculate the intensity of other optical signals of each sub-pixel point in a calculation mode corresponding to the first gear.
And expanding the encryption gear on the screen of the mobile terminal in a pull-down menu manner, and selecting the encryption gear on the menu.
Wearable equipment can judge which gear is that mobile terminal's current gear according to the luminance of the monochromatic light signal that mobile terminal sent out, and then wearable equipment adjusts self gear to the gear corresponding with mobile terminal's encryption gear again. Each gear corresponds to a calculation mode, the calculation modes corresponding to different gears are different, the intensity of other optical signals of each sub-pixel point can be calculated in the corresponding calculation mode only when the gear of the wearable device corresponds to the gear of the mobile terminal, and if the gear of the wearable device does not correspond to the gear of the mobile terminal, the wearable device cannot calculate the brightness of other optical signals of each sub-pixel point. For example, when the encryption gear on the mobile terminal is set as the first gear, the screen of the corresponding mobile terminal displays pure red, the wearable device can judge that the current gear of the mobile terminal is the first gear according to the fact that the brightness of a red light signal emitted by the mobile terminal is pure red, then the wearable device adjusts the gear of the wearable device to the first gear corresponding to the gear of the mobile terminal, and therefore the intensity of the blue light signal and the green light signal of each sub-pixel point can be calculated by using the first calculation mode corresponding to the first gear.
It should be noted that, the number of shift positions can be more than three, and since there are many different color levels of red, a plurality of different shift positions can be set, which is only an example.
Wearable equipment can judge which gear is the current gear of mobile terminal according to the luminance of the monochromatic light signal that mobile terminal sent out, and then adjusts self gear to the gear corresponding with mobile terminal's gear. In addition to this, the gear of the wearable device may be manually adjusted to correspond to the gear of the mobile terminal. For example, the current gear of the mobile terminal is set as the second gear, and then the user adjusts the gear of the wearable device to the second gear, so that the gear of the wearable device corresponds to the gear of the mobile terminal, and at this time, the wearable device calculates the intensity of the other optical signals of each sub-pixel point in a second calculation mode corresponding to the second gear.
Optionally, before the adjusting the gear to the first gear corresponding to the first brightness, where the brightness of the screen is adjusted to the first brightness, and the first gear corresponds to the first calculation method, the method further includes:
setting a plurality of gears including the first gear, wherein each gear corresponds to different calculation modes, and each gear corresponds to different brightness of the screen.
And corresponding calculation modes are provided for each encryption gear, and the intensities of the blue light and the green light corresponding to the red light on each sub-pixel point are calculated by using different calculation modes under different encryption gears. Therefore, the user can flexibly select different gears according to the self requirement to encrypt the content on the screen of the mobile terminal, so that the encryption effect is better.
Optionally, the first optical signal is a monochromatic optical signal;
the second optical signal is other monochromatic optical signals except the first optical signal;
the third optical signal is a polychromatic optical signal.
The first optical signal is a monochromatic light signal, such as a red light signal, the second optical signal is a blue light signal or a green light signal, and the third optical signal is a polychromatic light signal synthesized from the monochromatic light signals.
In step S103, the red light emitted by the screen of the mobile terminal reaches the wearable device, and the wearable device calculates the intensity of the corresponding blue light and green light according to the intensity of the red light of each sub-pixel, and since the intensity of the red light of each sub-pixel is different, the calculated intensity of the blue light and green light is also different, and finally the lights corresponding to the three colors of each sub-pixel are synthesized, so that a picture with various colors is formed, and at this time, the user can see the content displayed on the screen of the mobile terminal.
In this embodiment, the user uses wearable equipment to watch the mobile terminal screen, can acquire the content that shows on the mobile terminal screen, simultaneously because what shows on the screen of mobile terminal is monochromatic light, and not direct display content, other people can't acquire the content on the screen of mobile terminal to set up different gears and encrypt, the user can set up the encryption gear in a flexible way according to self needs, consequently can play the effect that prevents other people to steal the content that shows on the mobile terminal screen.

step S201, setting a plurality of calculation modes including the first calculation mode, wherein each calculation mode corresponds to a brightness of the first screen.

Step S203, outputting a first optical signal on the first screen and sending the first optical signal to a wearable device, so that the wearable device calculates, according to the intensity of the first optical signal output by each sub-pixel of the first screen, the intensity of at least one second optical signal of each sub-pixel except the first optical signal, and synthesizes, by the wearable device, the first optical signal of each sub-pixel and the corresponding at least one second optical signal with calculated intensity to obtain a third optical signal, and outputs the third optical signal.
In step S201, a plurality of encryption steps may be set on the mobile terminal, each encryption step corresponding to a calculation method, and each encryption step corresponding to a brightness of the first screen. Correspondingly, a plurality of encryption gears are also arranged on the wearable device, and the encryption gears on the mobile terminal and the encryption gears on the wearable device are in one-to-one correspondence. Through setting up different encryption gears, the user can use different gears to encrypt the content on the mobile terminal screen in a flexible way according to self needs, makes encryption effect better.
In step S202, the encryption gear of the mobile terminal is set as the first gear, the corresponding screen of the mobile terminal displays pure red, the encryption gear of the wearable device is also set as the first gear, and the intensity of blue light and green light corresponding to the intensity of red light on each sub-pixel point is calculated by using the first calculation mode corresponding to the first encryption gear.
