Referring to fig. 1, an organic light emitting display 10 is provided in an embodiment of the present application. The organic light emitting display 10 may be a transparent organic light emitting display 10. The organic light emitting display panel 10 may be used for a vehicle display. The organic light emitting display panel 10 may be used as a glass of a vehicle, for example. When the organic light emitting display 10 is turned on, the organic light emitting display 10 may display a picture such as a moving picture. The organic light emitting display panel 10 includes a transparent substrate 110, a pixel unit 120, and a color changing unit 130. The pixel unit 120 is disposed on one side of the transparent substrate 110. The number of the pixel units 120 is at least two. The color-changing unit 130 has a light-shielding function and a light-transmitting function. The color-changing unit 130 and the pixel unit 120 are disposed on the same side of the transparent substrate 110 or disposed on two opposite sides of the transparent substrate 110 respectively. The projection of the color-changing unit 130 on the transparent substrate 110 is located between two of the pixel units 120.
The color-changing unit 130 may be disposed on the same side of the transparent substrate 110 as the pixel unit 120, for example, the color-changing unit 130 and the pixel unit 120 may be disposed on the light emitting side of the transparent substrate 110. The color-changing unit 130 and the pixel unit 120 may be disposed on two opposite sides of the transparent substrate 110, respectively. The projection of the color-changing unit (130) on the transparent substrate (110) is located between the two pixel units (120), that is, whether the color-changing unit 130 and the pixel unit 120 are disposed on the same side or two sides of the transparent substrate 110, the vertical projection of the color-changing unit 130 on the transparent substrate 110 is located between the two vertical projections of the two pixel units 120 on the transparent substrate 110.
The transparent substrate 110 may be a silicone or polyester material. In one embodiment, the transparent substrate 110 may employ acrylonitrile-butadiene-styrene copolymer. When the organic light emitting display 10 does not display a picture, the transparent substrate 110 does not prevent glasses from viewing objects behind the organic light emitting display 10. When the organic light emitting display panel 10 is turned on, the pixel units 120 may cooperate to display various patterns. The pixel unit 120 may include a plurality of sub-pixels. The sub-pixels may be divided into red, blue and green sub-pixels. When the pixel unit 120 is lit, the color changing unit 130 activates a light shielding function. At this time, in the area where the color changing unit 130 is located, the light transmitted by the organic light emitting display 10 is reduced or opaque, and at this time, the color changing unit 130 makes the periphery of the pixel unit 120 darken, so that the contrast of the display of the pixel unit 120 is relatively improved, that is, the display of the pixel unit 120 is relatively brighter, and the picture color is brighter. When the pixel unit 120 does not work, the color changing unit 130 starts a light transmission function. At this time, at the position of the color changing unit 130, the organic light emitting display 10 is in a transparent state, and the entire organic light emitting display 10 is in a transparent state.
The color-changing unit 130 may be made of electrochromic material. The electrochromic material can be an organic electrochromic material, such as polythiophene and derivatives thereof, viologen, tetrathiafulvalene, metal phthalocyanine compounds and the like. When the electrochromic material is an inorganic electrochromic material, the inorganic electrochromic material can be tungsten trioxide. The color-changing unit 130 can also be a shielding sheet, and when the pixel unit 120 is lighted, the color-changing unit 130 starts a light shielding function. The shielding sheet moves to a position parallel to the display panel to shield light from penetrating the organic light emitting display 10. When the pixel unit does not work, the color changing unit 130 starts a light transmitting function, and the shielding sheet can be perpendicular to the display panel. The shielding sheet and the gap between the shielding sheets can be used for transmitting light to increase the light transmission capability of the organic light emitting display screen 10.
In the organic light emitting display 10 provided by the embodiment of the present application, the transparent substrate 110 is provided with at least two pixel units 120 and a color-changing unit 130. The color-changing unit 130 and the pixel unit 120 are disposed on the same side of the transparent substrate 110 or disposed on two opposite sides of the transparent substrate 110 respectively. The projection of the color-changing unit 130 on the transparent substrate 110 is located between two adjacent pixel units 120. The color-changing unit 130 has a light-shielding function and a light-transmitting function. When the pixel unit is lighted, the color changing unit 130 starts a light shielding function, so that light passing through the organic light emitting display screen 10 is reduced, light and shade contrast between the area where the pixel unit 120 is located and the area where the color changing unit 130 is located is increased, brightness of the area where the pixel unit 120 is located is improved, and a visual effect is improved.
It is understood that the color-changing unit 130 may have a multi-layered structure. The color-changing unit may include two electrode plates disposed opposite to each other. The two electrode plates can be respectively connected with the positive electrode and the negative electrode of a power supply. The two electrode plates may have a light shielding structure therebetween. The shading structure can have two position changes of shading and transmitting light. When the electrode plates are electrified, the light shielding structure can change at two positions of light shielding and light transmission due to the change of the electric field between the two electrode plates.
In one embodiment, the pixel units 120 are arranged in an array on the transparent substrate 110. The pixel units 120 may be arranged in a matrix, a diamond array, or the like. The color changing unit 130 is disposed between any two adjacent pixel units 120. When the pixel units 120 are arranged in a matrix, the color-changing unit 130 may be disposed between two adjacent pixel units 120 in each row of the matrix of pixel units 120, or disposed between two adjacent pixel units 120 in each column of the matrix of pixel units 120. In this way, the color changing units 130 are uniformly distributed in the display panel corresponding to each pixel unit 120. Therefore, whether the color changing unit 130 starts the light shielding function or the light transmitting function, the display brightness of the organic light emitting display panel 10 can be kept consistent.
In one embodiment, a plurality of the pixel units 120 are sequentially arranged to form a plurality of pixel unit rows 220. The plurality of color-changing units 130 are sequentially arranged to form a plurality of color-changing unit rows 240. The color-changing units 130 in the color-changing unit row 240 are connected in sequence, that is, in each color-changing unit row 240, the color-changing units 130 can be continuously arranged without interruption. The plurality of pixel unit rows 220 and the plurality of color-changing unit rows 240 are alternately arranged in sequence. The pixel unit rows 220 may be arranged in a straight line. The color-changing cell rows 240 may also be arranged in a straight line. The pixel cell row 220 and the color changing cell row 240 may be arranged in parallel. The plurality of pixel unit rows 220 and the plurality of color-changing unit rows 240 are alternately arranged in sequence, that is, one pixel unit row 220 and one color-changing unit row 240 are repeatedly arranged. In one embodiment, the number of pixel cells 120 in the pixel cell row 220 may be the same as the number of pixels in the pixel cell column 210.
In one embodiment, a plurality of the pixel units 120 are sequentially arranged to form a plurality of pixel unit columns 210. The pixel cell columns 210 are arranged to intersect the pixel cell rows 220. The plurality of color-changing units 130 are sequentially arranged to form a plurality of color-changing unit columns 230, and the plurality of color-changing units 130 in the color-changing unit columns 230 are sequentially connected. That is, in each of the color-changing unit columns 230, a plurality of the color-changing units 130 are continuously arranged without interruption. The color-changing cell columns 230 are arranged to intersect with the color-changing cell rows 240. The plurality of pixel unit columns 210 and the plurality of color-changing unit columns 230 are alternately arranged in sequence. In one embodiment, the pixel cell columns 210 and the pixel cell rows 220 may be arranged vertically. The color-changing cell columns 230 and the color-changing cell rows 240 can also be arranged vertically. The pixel cell column 210 and the color changing cell column 230 may be disposed in parallel. The plurality of pixel unit columns 210 and the plurality of color-changing unit columns 230 are alternately arranged in sequence, that is, one pixel unit column 210 and one color-changing unit column 230 may be repeatedly arranged.
In one embodiment, the number of the pixel units 120 in each of the pixel unit columns 210 and the number of the color-changing units 130 in each of the color-changing unit columns 230 may be the same. Thus, the pixel cell row 220, the pixel cell column 210, the color-changing cell row 240, and the color-changing cell column 230 constitute a matrix form. The matrix arrangement structure is simple, and the pixel units 120 and the color-changing units 130 are uniformly arranged in the matrix, so that the uniformity of the display brightness of the whole organic light-emitting display screen 10 in different modes can be improved.
It is understood that all of the color-changing cells 130 in the color-changing cell row 240 and all of the color-changing cells 130 in the color-changing cell column 230 may be connected in sequence. That is, the color-changing unit rows 240 may be sequentially arranged to form a color-changing unit strip structure. The color-changing unit rows 230 can also be arranged in sequence to form a color-changing unit strip structure. And the color-changing cell column 230 and the color-changing cell 130 are integrally connected at positions crossing each other. The plurality of color changing units 130 are connected in sequence, so that the color changing units are convenient to manufacture and install, and the production efficiency can be improved.
It is understood that the color-changing units 130 may be connected to each other to form a net structure. The pixel unit 120 may be disposed in each mesh of the mesh structure.
In one embodiment, the color changing unit 130 includes a liquid crystal dimming film 132. The liquid crystal dimming film 132 is disposed between two of the pixel units 120. The liquid crystal dimming film 132 may be parallel to the plane of the organic light emitting display panel 10. The liquid crystal dimming film 132 can be made by injecting a liquid crystal and mixture material into two transparent conductive films.
Referring to fig. 2, when the liquid crystal light adjusting film 132 is powered on, the liquid crystal molecules are aligned, and light can pass through the liquid crystal light adjusting film 132. Namely, the light transmission function of the color-changing unit 130 is turned on.
Referring to fig. 3, when the liquid crystal dimming film 132 is powered off, the liquid crystal molecules are arranged in disorder, and the liquid crystal molecules block light from passing through the organic light emitting display 10. At this time, the light shielding function of the color changing unit 130 is turned on.
In one embodiment, a pixel defining layer 140 is disposed between adjacent pixel units 120, and the liquid crystal dimming film 132 is disposed on a side surface of the pixel defining layer 140 away from the transparent substrate (110). It is understood that, when the pixel unit 120 is manufactured, the driving array layer 170 formed of the thin film transistor may be formed on the surface of the transparent substrate 110. Then, according to the arrangement of the thin film transistors, an insulating layer, an electrode layer, a light emitting layer, and the like may be formed on the surface of the driving array layer 170 to form the pixel unit 120. A separation column or other hierarchical structure may be formed between two adjacent pixel units 120. The separator and the like hierarchical structure may constitute the pixel defining layer 140. Therefore, by disposing the liquid crystal dimming film 132 on the surface of the pixel defining layer 140, the original frame structure of the pixel units 120 can be changed without increasing an additional area and changing the pitch between the pixel units 120. And the arrangement between the pixel unit 120 and the color-changing unit 130 on the surface of the organic light-emitting display screen 10 can be more compact, thereby improving the display effect.
In one embodiment, the organic light emitting display panel 10 further includes a control unit 150. The control unit 150 is electrically connected to the pixel unit 120 and the color changing unit 130, respectively. When the pixel unit 120 is turned on, the control unit 150 controls the color changing unit 130 to turn on the light shielding function, and when the pixel unit 120 is turned off, the control unit 150 controls the pixel unit 120 to turn on the light transmitting function. The control unit 150 may be a pixel driving module. The pixel driving module may be electrically connected to a thin film transistor that controls the pixel unit 120 to be turned on and off, and the pixel driving module may be electrically connected to the color changing unit 130. The pixel driving module may set a corresponding control signal according to a timing sequence of a scan signal, and when the scan signal drives the thin film transistor to display the pixel unit 120, the pixel driving module may simultaneously control the color changing unit 130 to be in a light-shielding state. When the pixel driving module does not output the scan signal, the pixel driving module may control the color changing unit 130 to be in a transmissive state.
In one embodiment, the ratio of the widths of the color-changing cell 130 and the pixel cell 120 is 1:3 to 5: 12. The width ratio may be a ratio of maximum diameters of the pixel unit 120 and the color changing unit 130. Within this range, when the organic light emitting display 10 is viewed, the display effect can be improved without a feeling of image separation by the color changing unit 130.
The embodiment of the application also provides a display device. The display device comprises the organic light-emitting display screen. The display device can be a tablet computer, a mobile terminal, a vehicle-mounted organic light-emitting display screen, an electronic device such as a sports bracelet and the like.
