A color gamut adjustment method and display device

Abstract

The invention discloses a color gamut adjusting method and a display device. The color gamut adjusting method is used for adjusting the display colour gamut of the display device, wherein each pixel of the display device at least comprises red sub-pixels, green sub-pixels, first blue sub-pixels and second blue sub-pixels. The color gamut adjusting method comprises the following steps: acquiring the current color gamut of the display device; acquiring the wavelength of blue light waves emitted by the display device under the current color gamut; judging that whether the wavelength of blue light waves is smaller than the set threshold value or not, if so, enabling the first blue sub-pixels or the second blue sub-pixels according to the color gamut selecting mode of the user, otherwise, enabling the second blue sub-pixels, wherein the wavelength of the blue light waves corresponding to the first blue sub-pixels is greater than that of the blue light waves corresponding to the second blue sub-pixels. According to the method and the device provided by the invention, the color gamut of the display device can be adjusted according to the choice of the user, and the harm caused to the eyes by the blue light can be alleviated without the additional hardware device.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technologies, and in particular, to a color gamut adjustment method and a display device. Background technique [0002] OLED (Organic Light Emitting Diode, Organic Light Emitting Diode) display is a self-luminous display. Compared with LCD (liquid crystal display, liquid crystal display), OLED display does not require a backlight source, so OLED display is thinner and lighter. In addition, OLED display is also It has the advantages of high brightness, low power consumption, wide viewing angle, high response speed, and wide operating temperature range, and is increasingly used in various high-performance display fields.

Problems solved by technology

[0003] Currently available OLED screens on the market usually emit high-energy short-wave blue light. The photons of short-wave blue light in visible light are likely to cause damage to the human retina, such as causing necrosis of retinal or lens cells, macular degeneration or cataracts, etc.

In addition, long-term use of such products can also cause visual fatigue, eye muscle and lens tension, and deepening of myopia, which will affect people's health.
