Fig. 1 is a flow chart of a display method provided by an embodiment. The display method is applied to a display device, and the display device includes a display screen and a light source provided on the back of the display screen. The display screen can be configured in the form of a liquid crystal display (LCD), and the specific form is not limited in this application.

As shown in Fig. 1, the display method includes steps 110 to 130, wherein:

Step 110: Acquire surrounding environment brightness information, and classify brightness levels according to the environment brightness information.

The environmental brightness information may specifically be an environmental brightness value, which refers to the ratio of the luminous intensity of the light-emitting surface in a specified direction to the area of the light-emitting surface perpendicular to the specified direction. After obtaining the environmental brightness information, the current environmental brightness information is divided into brightness levels. According to changes in environmental brightness, human vision can be defined as three types: photopic vision, scotopic vision, and intermediate vision. Among them, photopic vision: it is generally considered that the ambient brightness is greater than 3cd/m ² , and the peak of the human eye’s spectral luminous efficiency curve corresponds to a wavelength of 555nm; scotopic vision: the vision when the ambient brightness is less than 10 ^-3 cd/m ² , the human eye The peak value of the spectral optical efficiency curve corresponds to a wavelength of 507nm; intermediate vision: generally considered to be the vision when the ambient brightness is between 10 ^-3 cd/m ² ～3cd/m ² , and the peak of the spectral visual efficiency curve is from the corresponding 555nm Gradually shift to 507nm. In this embodiment, the brightness level is divided into three levels of scotopic vision, photopic vision, and intermediate vision according to human vision. Wherein scotopic environmental luminance is less than 10 ^-3 cd / m ^2, the ambient brightness is greater than the photopic 3cd / m ^2, the ambient brightness in mesopic vision is between ^{^{^{2 10 -3 cd / m 2 ~}}} 3cd / m.

In an embodiment, the brightness of the environment around the display screen can be obtained through a brightness sensor. The brightness sensor can be arranged on the front of the display device, and the front of the display device can be understood as the side where the display screen is installed. The brightness sensor installed on the front of the display device can detect the environmental brightness information in the side range corresponding to the front of the display screen. In an embodiment, the ambient brightness value detected by the brightness sensor at the current moment may be used as the ambient brightness information, so that the ambient brightness information can be quickly obtained. It is also possible to perform an average calculation on the environmental brightness information over a period of time, and use the average brightness information over a period of time as the environmental brightness information. In this way, a relatively average environmental brightness value can be obtained as the environmental brightness information.

Step 120: Adjust the light-emitting spectrum of the light-emitting source according to the environmental brightness information and the brightness level.

When the environmental brightness changes, the visual state of the human eye also changes. In order to make the viewer's eyes reach a comfortable state under different environmental brightness, this embodiment adjusts the light emission spectrum of the light source according to the environment brightness information, so that the light emission spectrum of the light source matches the environment brightness.

In one embodiment, the light source adopts an edge-lit light bar, on which a first light-emitting circuit and a second light-emitting circuit with two different light-emitting spectra are arranged; the light-emitting circuit is adjusted according to the environmental brightness information and the brightness level. The operating currents of the first light-emitting circuit and the second light-emitting circuit are such that the first light-emitting circuit operates in the first light-emitting spectrum and/or the second light-emitting circuit operates in the second light-emitting spectrum.

Specifically, when the brightness level is photopic, the current of the first light-emitting circuit and the second light-emitting circuit is adjusted to control the first light-emitting circuit to operate in the first light-emitting spectrum, and the second light-emitting circuit does not work. According to the human visual function curve shown in Figure 2, when the brightness level is photopic vision, the human eye is most sensitive to light with a wavelength of 555nm. Therefore, the peak wavelength of the first luminescence spectrum in this embodiment is set to 555nm, thus Make the luminous spectrum of the luminous source conform to the visual function of the human eye.

When the brightness level is scotopic vision, by adjusting the currents of the first light-emitting circuit and the second light-emitting circuit to control the second light-emitting circuit to work in the second light-emitting spectrum, the first light-emitting circuit does not work. According to the human visual function curve shown in Figure 2, when the brightness level is scotopic vision, the human eye is most sensitive to light with a wavelength of 507nm. Therefore, the peak wavelength of the second luminescence spectrum in this embodiment is set to 507nm, thus Make the luminous spectrum of the luminous source conform to the visual function of the human eye.

When the brightness level is intermediate vision, by adjusting the current of the first light-emitting circuit and the second light-emitting circuit to control the first light-emitting circuit to work in the first light-emitting spectrum, the second light-emitting circuit to work in the second light-emitting spectrum, and the first light-emitting circuit does not jobs. According to the human visual function curve shown in Figure 2, when the brightness level is scotopic vision, the human eye is more sensitive to light with a wavelength of 507nm to 555nm. Therefore, this embodiment controls the first light-emitting circuit and the second light-emitting circuit Work at the same time, and control the common emission spectrum wavelength of the first light-emitting point and the second light-emitting circuit to be between 507nm and 555nm, so that the light-emitting spectrum of the light-emitting source conforms to the visual function of the human eye.

In step 130, the image is displayed under the luminescence spectrum of the luminescence source.

Since the display screen itself does not emit light, the display screen needs to achieve a display effect through transmission or reflection through an external light source. In this embodiment, the display screen displays an image according to the received light emission spectrum of the back light source.

The display method provided in this embodiment includes obtaining surrounding environment brightness information, and dividing brightness levels according to the environment brightness information; adjusting the light emission spectrum of the light source according to the environment brightness information and the brightness level; The image is displayed below. The above display method adjusts the luminescence spectrum of the luminous source according to the different brightness levels, so that the luminescence spectrum of the display device can conform to the visual function of the human eye in different environments, so that the human eye of the viewer can reach under different environments. Comfortable state.

Step 310: If the brightness level is scotopic vision, control the first light-emitting circuit to operate at a standard operating current, and control the second light-emitting circuit to stop working, so that the light-emitting source operates in the first light-emitting spectrum.

Step 320: If the brightness level is photopic, control the second light-emitting circuit to operate at a standard operating current, and control the first light-emitting circuit to stop working, so that the light-emitting source operates in the second light-emitting spectrum.

Step 330: If the brightness level is intermediate vision, calculate the first working current and the second working current according to the environmental brightness information and the standard working current, and control the first light-emitting circuit to work at the first working current, and control all The second light-emitting circuit works at the second working current, so that the peak wavelength of the light-emitting spectrum of the light-emitting source is between 507 nm and 555 nm.

Specifically, the calculating the first working current and the second working current according to the environmental brightness information and the standard working current includes:

The first working current formula is Ia=(La-0.001)*Istd/2.999;

The second working current formula is Ib=(3-La)*Istd/2.999;

Among them, La represents environmental brightness information; Istd represents standard operating current.

Since the ambient brightness is greater than 3 nits, it is a photopic environment, and when the ambient brightness is 0.001 nits, it is a scotopic environment, 2.999=3-0.001.

It should be noted that the standard operating current is determined by the power of the light-emitting diode used in the specific light-emitting circuit, and is not a constant value.

In an embodiment, the first light-emitting circuit includes a plurality of first light-emitting diodes connected in series, and the second light-emitting circuit includes a plurality of second light-emitting diodes connected in series; and each of the first light-emitting diodes and the The brightness of the second light emitting diode can be the same under the standard operating current, so that the brightness of the display device can be the same in different environments.

Separate control is to facilitate the adjustment of the current of different light-emitting diodes.
