Device includes the display device that above-described embodiment three provides, and the specific descriptions about the display device can be found in above-described embodiment
Three, details are not described herein again.Wherein, optical device is used to receive through the light of the first sub-pixel or through the second sub-pixel
Light.For example, optical device is glasses.
Fig. 6 is the structural schematic diagram of optical device, as shown in fig. 6, optical device is colored by multiple first in the present embodiment
Filter unit 3 is constituted, therefore optical device can receive the light through the first sub-pixel, in the present embodiment, it is preferable that Duo Ge
One colored light-filtering units 3 include the first red filter unit, the first green filter unit and the first blue filter unit, and first is red
The range of the light transmitting wavelength of color filter unit is 710 nanometers to 730 nanometers, the range of the light transmitting wavelength of the first green filter unit
It is 545 nanometers to 550 nanometers, the range of the light transmitting wavelength of the first blue filter unit is 465 nanometers to 475 nanometers.Alternatively, light
It learns equipment to be made of multiple second colored light-filtering units 3, therefore optical device can receive the light through the second sub-pixel, this reality
It applies in example, it is preferable that multiple second colored light-filtering units 3 include the second red filter unit, the second green filter unit and the
Two blue filter units, the range of the light transmitting wavelength of the second red filter unit are 680 nanometers to 700 nanometers, the second green filter
The range of the light transmitting wavelength of light unit is 550 nanometers to 555 nanometers, and the range of the light transmitting wavelength of the second blue filter unit is
450 nanometers to 460 nanometers.Specific descriptions about the first colored light-filtering units and the second colored light-filtering units can be found in above-mentioned reality
The description in example one to the first colored light-filtering units and the second colored light-filtering units is applied, details are not described herein again.
In the present embodiment, make optical device the step of can be found in above-described embodiment one to production the first colorized optical filtering list
The description of the step of member and the second colored light-filtering units, details are not described herein again.
In the technical solution of display system provided by the present embodiment, display base plate include underlay substrate and be located at substrate base
Multiple the first sub-pixels being arranged successively and the second sub-pixel corresponding with each first sub-pixel on plate, the first sub-pixel and
The color of corresponding second sub-pixel is identical, the light transmitting wavelength of the range of the light transmitting wavelength of the first sub-pixel and the second sub-pixel
Range is different.Under naked state, naked eye viewer will be unable to clearly watch the hidden picture in display device, only wear
Specific optical device can just see hidden picture, to achieve the effect that peep-proof, and be also less prone to be therefore easily perceived by humans, to improve
User watches the concealment and safety of confidential information in display device.
It is understood that the principle that embodiment of above is intended to be merely illustrative of the present and the exemplary implementation that uses
Mode, however the present invention is not limited thereto.For those skilled in the art, essence of the invention is not being departed from
In the case where mind and essence, various changes and modifications can be made therein, these variations and modifications are also considered as protection scope of the present invention.
