The display may be, but is not limited to, displays on various personal computers, notebook computers, smart phones, tablet computers, and portable wearable devices, among others.
In order to explain the technical means of the present invention, the following description will be given by way of specific examples.
The first embodiment is as follows:
fig. 2 is a schematic flow chart illustrating an implementation of a display control method according to an embodiment of the present invention. As shown in fig. 2, the method for controlling display of a display specifically includes the following steps 101 to 104.
Step 101: and monitoring the on-off state of a display control key of the display.
The on-off state of the display control key comprises an on state and an off state. Alternatively, the display program is called to monitor the on-off state of the display control key of the display, and the calling operation may be performed by a processor inside the display.
Step 102: and if the display control key is in an open state, determining the type of the display control key according to the key value of the display control key.
The key values of the display control keys can be predefined, preferably, the display control keys comprise a plurality of categories, and each category corresponds to one key value. For example, the key values may be set according to quaternary, octal, and hexadecimal.
Step 103: and determining the light-emitting wavelength and the light-emitting power of at least one backlight color lamp of the red backlight lamp, the green backlight lamp and the blue backlight lamp according to the type of the display control key.
The display control keys comprise color display keys and function keys. The color display keys include, but are not limited to, a red display key, a green display key, and a blue display key. The function keys include, but are not limited to, a color temperature key, a contrast key, and a brightness key.
The light emission wavelength of the red backlight is 700nm, the light emission wavelength of the green backlight is 546.1nm, and the light emission wavelength of the blue backlight is 435.8 nm.
When the red display key is in an on state (e.g., pressed), the light emission wavelength of the red backlight is determined to be 700nm, and the light emission power of the red backlight is determined. When the green display key is in an on state (e.g., pressed), the light emission wavelength of the green backlight is determined to be 546.1nm, and the light emission power of the green backlight is determined. When the blue display key is in an on state (e.g., pressed), the light emission wavelength of the blue backlight is determined to be 546.1nm, and the light emission power of the blue backlight is determined.
It should be noted that: when two display keys of the red display key, the green display key and the blue display key are in an open state (e.g., pressed), the wavelength of the backlight color lamp is respectively determined, and the light emitting power of the backlight color lamp is respectively determined. When all of the red display key, the green display key, and the blue display key are in an on state (e.g., pressed), the wavelengths of the red backlight, the green backlight, and the blue backlight are determined, respectively, and the light emission powers of the red backlight, the green backlight, and the blue backlight are determined, respectively.
When the color temperature key is in an on state (e.g., pressed), the wavelengths of the red backlight, the green backlight, and the blue backlight are determined, respectively, and the total light emission power of the red backlight, the green backlight, and the blue backlight is determined. When the contrast key is in an on state (e.g., pressed), the wavelengths of the red backlight, the green backlight, and the blue backlight are determined, respectively, and the total light emission power of the red backlight, the green backlight, and the blue backlight is determined. When the brightness key is in an on state (e.g., pressed), the wavelengths of the red backlight, the green backlight, and the blue backlight are determined, respectively, and the integrated light emission power of the red backlight, the green backlight, and the blue backlight is determined.
It should be noted that, when two keys among the color temperature key, the contrast key, and the brightness key are in an on state (e.g., pressed), the wavelengths of the red backlight, the green backlight, and the blue backlight are determined, respectively, and the integrated light emission power of the red backlight, the green backlight, and the blue backlight is determined. When the color temperature key, the contrast key, and the brightness key are all in an on state (e.g., pressed), the wavelengths of the red backlight, the green backlight, and the blue backlight are determined, respectively, and the total light emission power of the red backlight, the green backlight, and the blue backlight is determined.
As an embodiment of the present invention, the luminous power of the backlight color lamp is determined by varying the current flowing through the backlight color lamp. Generally, the backlight color lamp allows continuous working current to be around 20mA, the red backlight has saturation phenomenon, and the brightness of the green backlight and the blue backlight is basically proportional to the flowing current. The current is controlled by the integrated circuit IC, and the current passing through the three backlight color lamps is adjusted, so that the luminous intensity of the three green backlight lamps is correspondingly changed, the change of the mixing proportion of the three primary colors is realized, and various colors can be generated. When the radiant power of light (the radiant power of light is referred to as luminous power) is different for light of the same wavelength, the feeling of brightness is different for humans. However, if the radiation power is the same and the wavelength is different, the perception of brightness is different.
Step 104: and adjusting the display effect of the at least one backlight color lamp according to the light-emitting wavelength and the light-emitting power.
Optionally, before step 104, further comprising:
step 105: and when a turning-off request of the blue backlight lamp is received, controlling the turning-off of the blue backlight lamp.
According to one embodiment of the present invention, the turning on and off of the blue backlight may be independently controlled, and when the blue backlight is turned on, the blue backlight is combined with the red backlight and the green backlight to achieve a predetermined display effect. When the blue backlight is turned off, the display no longer emits blue light, which is beneficial for reducing the visual impairment of the user using the display.
As an embodiment of the present invention, step 104 may comprise:
step 201: and if the display control key is a color display key, controlling the current and the bandwidth of the at least one backlight color lamp according to the light-emitting wavelength and the light-emitting power so as to adjust the color display effect of the at least one backlight color lamp.
Step 202: and if the display control key is a functional key, controlling the current and the frequency width of the red backlight, the green backlight and the blue backlight according to the light-emitting wavelength and the light-emitting power so as to adjust the display effect of the display.
As an embodiment of the present invention, step 201 may specifically include:
step 301: if the color display key is a red display key, the light-emitting wavelength and the light-emitting power of the red backlight are controlled through the current and the bandwidth so as to adjust the color display effect of the red backlight.
Step 302: if the color display key is a green display key, controlling the light-emitting wavelength and the light-emitting power of a green backlight lamp through the current and the frequency width so as to adjust the color display effect of the green backlight lamp.
Step 303: if the color display key is a blue display key, the light-emitting wavelength and the light-emitting power of the blue backlight are controlled through the current and the frequency width so as to adjust the color display effect of the blue backlight.
As an embodiment of the present invention, step 202 may specifically include:
step 401: and if the function key is a color temperature key, controlling the current and the bandwidth of the red backlight, the green backlight and the blue backlight according to the light-emitting wavelength and the light-emitting power so as to adjust the color temperature effect of the display.
The current is controlled by the integrated circuit IC, and the current passing through the three backlight color lamps is adjusted, so that the luminous intensity of the three backlight color lamps is correspondingly changed, the change of the mixing proportion of the three primary color lights is realized, and various color temperatures can be generated, thereby adjusting the color temperature effect of the display.
Step 402: and if the function key is a contrast key, controlling the current and the frequency width of the red backlight, the green backlight and the blue backlight according to the light-emitting wavelength and the light-emitting power so as to adjust the contrast effect of the display.
Here, it should be noted that: contrast refers to the measurement of different brightness levels between the brightest white and darkest black areas in an image, and a larger difference range represents a larger contrast, and a smaller difference range represents a smaller contrast. The contrast is adjusted by adjusting the brightness. The manner of adjusting the brightness is explained in step 403, and is not described in detail here.
Step 403: and if the function key is a brightness key, controlling the current and the frequency width of the red backlight, the green backlight and the blue backlight according to the light-emitting wavelength and the light-emitting power so as to adjust the brightness effect of the display.
Here, it should be noted that: the current is controlled by the integrated circuit IC, and the current passing through the three backlight color lamps is adjusted, so that the luminous intensity of the three backlight color lamps is correspondingly changed, the mixing proportion of the three primary color lights is changed, various brightness can be generated, and the brightness effect of the display is adjusted.
Alternatively, the brightness may also be adjusted by implementing a gray scale control by means of a pulse width modulation method, i.e. periodically varying the light pulse width (i.e. duty cycle), as long as the period of this repeated lighting is sufficiently short (i.e. the refresh frequency is sufficiently high), the human eye does not perceive the light emitting pixels as jittering.
In the embodiment of the invention, the on-off state of a display control key of a display is monitored, if the display control key is in the on state, the type of the display control key is determined according to the key value of the display control key, and then the light-emitting wavelength and the light-emitting power of at least one backlight color lamp of a red backlight lamp, a green backlight lamp and a blue backlight lamp are determined according to the type of the display control key; finally, the display effect of the at least one backlight color lamp is adjusted according to the light emitting wavelength and the light emitting power, the red backlight lamp, the green backlight lamp and the blue backlight lamp are independently controlled, the display mode of the display is flexible, the display effect of the display is improved, and the display has high usability and practicability.
It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present invention.
