Abstract
The invention relates to an electrochromic photosensitive display screen. At present, an LCD (liquid crystal display) screen reaches the large-scale commercialized production level, however, the disadvantages of higher manufacturing cost, smaller visual angle, lower response speed, liquid crystal dead pixels, low brightness and contrast ratio and the like are urgent to be improved in the current LCD technology. The electrochromic photosensitive display screen comprises a display screen, wherein integral development is realized in the display screen by the aid of multiple pixel points; the electrochromic photosensitive display screen is characterized in that the pixel points are made of red, green and blue electrochromic materials, and the depth of the three colors is regulated according to different driving voltage. The integral display performance of the electrochromic display screen can be improved, the electrochromic screen can have the self-photosensitive effect, then photoluminescence of an outer light source or the electrochromic materials is driven to be stronger, and the purpose of screen brightness change is achieved.
Description
Technical field
The present invention relates to the photosensitive display screen of a kind of electrochromism.
Background technology
Nowadays, LCD display has reached large-scale commercial production level, LCD display technique also relative maturity.But to be also current LCD display technique in urgent need to be improved and improve for the shortcomings such as cost is higher, visible angle is less, response speed is comparatively slow, liquid crystal bad point, brightness and contrast are low.Meanwhile, amorphous WO is found from Deb in 1969
3since (tungstic acid) has electrochromic property, discovery and the development of various organic and inorganic off-color material are extensively studied by scientific research personnel.Electrochromic device (ECD) manufacture craft made with it also reaches its maturity, and main application fields has: display screen, smart window, anti-dazzle minute surface, variable color safety goggles etc.But, the subject matter that slow, the frequent variable color power consumption of response speed is large, the not high defect of display life is also electrochromic device.
Because electrochromic material exists, slow, the frequent variable color power consumption of response speed is large, the not high defect of display life, it is developed difficult in the display field (as: mobile phone screen, computer and television indicator etc.) that frame number requirement is high.Disobey backrest light source due to electrochromic material on the other hand and provide light, often the raising of screen intensity is also the problem needing to solve.
Summary of the invention
The present invention is directed to the defect that prior art exists, there is provided a kind of electrochromism photosensitive display screen, the overall display performance of electrochromic display screen can be improved, allow electrochromism screen can reach from photosensitive effect, and then drive the photoluminescence grow of external light source or electrochromic material itself, the object of screen intensity change is reached with this.
For this reason, the present invention takes following technical scheme, the photosensitive display screen of electrochromism, comprise display screen, overall video picture is realized by multiple pixel in display screen, it is characterized in that described pixel is made up of red, green, blue three look electrochromic material, and regulate the depth of three kinds of colors by different driving voltages.
The photoluminescence spectrum of described electrochromic material and absorption spectra are inverse ratio.
Photoreceptor and LED light source are installed in described display screen periphery, and utilize the average brightness that IC detects to calculate each photoreceptor, when mean value is below or above a certain value, the brightness that signal adjusts LED light source in real time can be provided, reach the brightness regulation of electrochromism screen with this.
As preferably, thiophene piperazine modification purpurine can be adopted to reach display red in pixel; Poly-4-diphenylamine benzaldehyde-4,8-diethylhexyl oxygen benzene [1,2-b; 3,4-b] two thiophene (PBDTTPA-CHO) are as pixel Green display material; In pixel, blue electrochromic material is selected Prussian blue.
ECD display screen is on the market the Memorability utilizing electrochromic material now, and after namely removing voltage, the color of material still can maintain a few hours to one month, and product mostly is timer, scorer etc., but screen intensity cannot self-regulation.
The present invention is in conjunction with CF configuration in LCD and three primary colours mixing colour developing principle: with the colour developing of voltage driven red, green, blue three kinds of electrochromic materials, be a pixel with three independent display units, multiple pixel and composing images, by the color change of voltage driven material.Meanwhile, this electrochromic display screen has the function of two kinds of alternatives self-regulation brightness: one is that the brightness adopting CCD or photoresistance to control screen perimeter LED by IC reaches adjustment object; Two is adopt novel electrochromic material, and in strong light environment, the photoluminescence of material is on a declining curve, and in low light environment, the photoluminescence grow of material, reaches the adjustment of screen intensity with this.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the structural representation of photoreceptor of the present invention.
Embodiment
Below in conjunction with specific embodiment, set forth the present invention further.
As shown in Figure 1, the present invention includes display screen 2, realize overall video picture by multiple pixel 1 in display screen 2, pixel is made up of red, green, blue three look electrochromic material, and regulates the depth of three kinds of colors by different driving voltages.The photoluminescence spectrum of electrochromic material and absorption spectra are inverse ratio.
As shown in Figure 2, photoreceptor 4 is installed in display screen periphery, and utilizes the average brightness that IC detects to calculate each photoreceptor, when mean value is below or above a certain value, the brightness that signal adjusts LED light source 3 in real time can be provided, reach the brightness regulation of electrochromism screen with this.
Further, thiophene piperazine modification purpurine is adopted to reach display red in pixel; Poly-4-diphenylamine benzaldehyde-4,8-diethylhexyl oxygen benzene [1,2-b; 3,4-b] two thiophene (PBDTTPA-CHO) are as pixel Green display material; In pixel, blue electrochromic material is selected Prussian blue.
The present invention is in conjunction with CF configuration in LCD and three primary colours mixing colour developing principle: with the colour developing of voltage driven red, green, blue three kinds of electrochromic materials, be a pixel with three independent display units, multiple pixel and composing images.Meanwhile, this electrochromic display screen has the function of two kinds of alternatives self-regulation brightness: one is that the brightness adopting CCD or photoresistance to control screen perimeter LED by IC reaches adjustment object; Two is adopt novel electrochromic material, and in strong light environment, the photoluminescence of material is on a declining curve, and in low light environment, the photoluminescence grow of material, reaches the adjustment of screen intensity with this.
