Description
Technical Field
The present invention relates to the field of electronic ink screens, and in particular, to an electronic ink screen, a light supplementing device, a light supplementing method, and a storage medium thereof.
Background
The ink layer of the electronic ink screen is provided with more than two kinds of particles capable of reflecting a spectrum in a specific wave band, and when the ambient light is sufficient, the particles are used for reflecting the incident light after being absorbed by the particles for a certain spectrum to display a picture. The electronic ink screen has the same display characteristics as natural paper, is passive reflective display, and has a good protection effect on eyes. Meanwhile, since the electronic ink screen is a passive display device, the electronic ink screen is difficult to use under the condition of dark light, a front light source is added to a general electronic ink screen EPD display product, and when the ambient light is insufficient, the front light source can be turned on to illuminate the screen.
When the electronic ink screen relies on reflection of an external light source (including an ambient light source and a front light source) for display, if a certain color is absent in the spectrum of the external light source, the electronic ink screen cannot display the corresponding color. In other words, when the external light source is a non-white light source (white light is formed by mixing light with different colors (i.e. different wavelengths)), the screen color representation of the ink screen will no longer be accurate, and no design scheme for color reproduction is considered in the current products on the market.

Detailed Description
In order to make the objects, features and advantages of the present invention more comprehensible, the technical solutions in the embodiments of the present invention are described in detail below with reference to the accompanying drawings, and it is apparent that the embodiments described below are only some embodiments of the present invention, but not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
In order to enable an ink screen product to display a true color effect to be displayed under any light source condition, the embodiment of the invention provides a light supplementing device for an electronic ink screen, which comprises:
A light emitting assembly;
the environment light detection component is used for acquiring the brightness and the spectrum of the current environment light in real time;
The analysis and calculation unit is used for calculating the luminous brightness and the color of the luminous component according to the brightness and the spectrum of the current ambient light, so that the light generated by the luminous component and the current ambient light can be synthesized into white light;
And the light-emitting control unit is used for controlling the light-emitting component to emit light according to the calculation result of the analysis and calculation unit.
It should be noted that, under the white light irradiation, the white light includes all wavelengths of light visible to human eyes, so the electronic ink screen can perform true color display under the white light irradiation, and inaccurate display caused by partial color missing of the irradiation light source is avoided. Based on the above, the embodiment of the invention detects the ambient light in real time to identify the brightness of the ambient light and the missing color in the spectrum thereof, and further controls the brightness and the color of the light-emitting component according to the detection result, so that the light generated by the light-emitting component complements the ambient light to form white light, thereby ensuring that the electronic ink screen can display good color display effect close to reality under the irradiation of various ambient lights.
The human eye recognizes the color based on the wavelength of the light that is seen. Most of the colors in the visible spectrum can be mixed by three basic color lights according to different proportions, namely (R), green (G) and blue (B) three primary colors. The three lights are mixed in the same proportion and reach a certain intensity, and white (white light) is displayed; if the intensities of the three lights are all zero, the light is black (dark).
RGB color mode is a color standard in industry, which is to obtain various colors by changing three color channels of red (R), green (G) and blue (B) and overlapping them with each other, and RGB is a color representing three channels of red, green and blue, and this standard includes almost all colors perceived by human eyesight, and is one of the most widely used color systems.
Based on this, in an alternative embodiment, the light emitting assembly in the light supplementing device may include a plurality of LED lamps, each including an R light emitting unit, a G light emitting unit, and a B light emitting unit. By adjusting the light emitting parameters of the R light emitting unit, the G light emitting unit and the B light emitting unit, the color with any required brightness can be realized.
In practical application, the light-emitting control unit is specifically configured to determine the R unit power supply parameter, the G unit power supply parameter, and the B unit power supply parameter according to the calculated light-emitting brightness and color of the light-emitting component, and accordingly adjust the working currents of the R light-emitting unit, the G light-emitting unit, and the B light-emitting unit. In other words, the current of the R light emitting unit, the G light emitting unit, and the B light emitting unit is adjusted and controlled by converting the calculation result into the power supply parameter, so that the target can be achieved.
In order to facilitate current control of the R light emitting units, the G light emitting units and the B light emitting units, the R light emitting units of all the LED lamps can be connected in series to form an R unit control branch, the G light emitting units of all the LED lamps are connected in series to form a G unit control branch, and the B light emitting units of all the LED lamps are connected in series to form a B unit control branch, so that current control is respectively carried out on the R unit control branch, the G unit control branch and the B unit control branch, unified current control on all the light emitting units can be achieved, and simplicity and high efficiency are achieved.
In the embodiment of the invention, the ambient light detection assembly may specifically include a spectrum sensor for acquiring the optical signal first, then performing data processing with different degrees, and finally obtaining spectrum information. The spectrum sensor can be arranged at the edge position of the screen of the electronic ink screen so as to avoid shielding the screen. Meanwhile, the number of the optical sensors in the embodiment of the present invention is not particularly limited.

Thus, white light formed by mixing light emitted by the light emitting component and ambient light can uniformly cover the whole screen, so that the whole display area of the screen can obtain a good consistent color display effect.
Based on the same inventive concept, the embodiment of the invention also provides an electronic ink screen, which comprises a screen and a light supplementing device for supplementing light to the screen, wherein the light supplementing device is the light supplementing device for the electronic ink screen.
Because different conventional light supplementing devices are adopted, the electronic ink screen of the embodiment of the invention can supplement ambient light no matter what color environment the electronic ink screen is applied to, so that white light is formed to irradiate on the surface of the screen of the electronic mode screen, and the screen is ensured to obtain a color display effect close to reality.

s1, acquiring the brightness and the spectrum of the current ambient light in real time.
S2, calculating the luminous brightness and the color of the luminous component according to the brightness and the spectrum of the current ambient light, so that the light generated by the luminous component and the current ambient light can be synthesized into white light.
