Only be described in detail for the first sub-pixed mapping group 1 below, second and the 3rd sub-pixed mapping group situation and the situation of the first sub-pixed mapping group similar, same section then repeats no longer one by one.
As shown in Figure 1, Figure 3 and Figure 4, described first sub-pixed mapping group 1 comprises the first sub-pixed mapping 11(R sub-pixed mapping of shared one drive circuit (referring to Fig. 5)) and the second sub-pixed mapping 12(C sub-pixed mapping), and the R sub-pixed mapping drive circuit all corresponding with it with C sub-pixed mapping is connected (Fig. 5 in detailed in Example two).
The structural representation of what Fig. 3 represented is R sub-pixed mapping.In figure 3, described R sub-pixed mapping 11 comprises white light OLED luminous element 111, ruddiness light splitting piece 112 and light barrier 4.Wherein, the corresponding red spectral band of described ruddiness light splitting piece 112, that is the light of the specific wavelength of ruddiness light splitting piece 112 output is ruddiness.
Light path principle in Fig. 3 is as follows: the white light (W that white light OLED luminous element 111 exports, White) divide in order to three-beam after ruddiness light splitting piece 112, wherein, being positioned at middle light beam is light (W-R) after white light deducts ruddiness, namely cyan light (C, Cyan), and the light beam being positioned at the right and left is ruddiness, due in the present embodiment, light splitting piece 112 is isosceles trapezoid, therefore the ruddiness being arranged in the right and left is 1/2nd of former white light energy red color light component separately, that is the two bundle ruddiness being positioned at both sides are 0.5*R.
For R sub-pixed mapping 11, need to export ruddiness (R), therefore, optionally stop and be positioned at middle cyan light (C, Cyan), form R sub-pixed mapping 11.
In like manner, the structural representation of what Fig. 4 represented is C sub-pixed mapping.In the diagram, described C sub-pixed mapping 12 comprises white light OLED luminous element 121, ruddiness light splitting piece 122 and light barrier 4, wherein, the ruddiness light splitting piece 122 of C sub-pixed mapping 12 identical wave band corresponding to the ruddiness light splitting piece 112 of R sub-pixed mapping 11, be corresponding red spectral band, that is the light of the specific wavelength of ruddiness light splitting piece 112 and 122 output is ruddiness.
Light path principle in Fig. 4 and Fig. 3 similar, difference be only light barrier 4 position difference.Because C sub-pixed mapping 12 needs to export cyan light (C), therefore, optionally stop the ruddiness (0.5*R) being positioned at both sides, wherein, the position of the light barrier 4 in Fig. 4 is relative complementary with the position of the light barrier 4 in Fig. 3, thus formed in Fig. 4 in C sub-pixed mapping 12, Fig. 3 and form R sub-pixed mapping 11, and the luminescence band summation of R sub-pixed mapping 11 and C sub-pixed mapping 12 is white light wave band.
As mentioned above, because the ruddiness light splitting piece in the present embodiment, green glow light splitting piece and blue light light splitting piece are isosceles trapezoid, then for second and the 3rd for sub-pixed mapping group, according to same principle, obtain after utilizing green glow light splitting piece being positioned at middle a branch of pinkish red coloured light (M, Magenta) and be positioned at two bundles green light (0.5*G) on both sides, and by the selective blocking of light barrier, G sub-pixed mapping that luminescence band summation is white light wave band and M sub-pixed mapping is realized; Obtain being positioned at middle a branch of sodium yellow (Y, Yellow) after utilizing blue light light splitting piece and be positioned at two of both sides and restraint blue light beam (0.5*B), and by the selective blocking of light barrier, realize B sub-pixed mapping that luminescence band summation is white light wave band and Y sub-pixed mapping.Further, again because white light (W) is divided into ruddiness (R, Red) wave band, green glow (G, Green) wave band and blue light (B, Blue) wave band on wave band, then the angle of above-mentioned light on wave band covers meets C=B+G; M=R+B; Y=R+G.
It should be noted that, in the present embodiment, the luminescence band summation of the first sub-pixed mapping (R sub-pixed mapping 11, G sub-pixed mapping 21 and B sub-pixed mapping 31) respectively in this sub-pixed mapping group is white light wave band; Meanwhile, respectively there is enough distances with the light splitting piece preventing the output light of sub-pixed mapping from entering adjacent sub-pixed mapping between this sub-pixed mapping, avoid causing the crosstalk between adjacent sub-pixed mapping.
What needs further illustrated is, the difference of the light splitting piece of corresponding different-waveband is the difference in its physical dimension, in each sub-pixed mapping, (the upper base edge lengths m2 of light splitting piece is comprised by the size adjusting light splitting piece, bottom length m1, height d1) and the relative distance of light splitting piece and white light OLED luminous element (comprise the upper base edge lengths m2 of light splitting piece, bottom length m1, height d1), the light presetting wave band is exported to make described light splitting piece, wherein, respectively the scope of this parameter m2, m1, d1 and d2 depends on the size of its OLED pixel matched.In the present embodiment, ruddiness light splitting piece, green glow light splitting piece and blue light light splitting piece are isosceles trapezoid, be directed to the square white light OLED luminous element that a length of side is 50 μm, preferably, for ruddiness light splitting piece: bottom length m1 is about 43 μm, upper base edge lengths m2 is about 33 μm, and d is highly about 114 μm, and the distance d2 between ruddiness light splitting piece and white light OLED luminous element is more 40 μm; For green glow light splitting piece: m1 is about 40 μm, m2 is about 35 μm, and d1 is about 67 μm, and d2 is about 40 μm; For blue light light splitting piece: m1 is about 34 μm, m2 is about 30 μm, and d1 is about 42 μm, and d2 is about 40 μm.
In order to make those skilled in the art understand principle of the present invention, execution mode and beneficial effect further, the labor of related content will be carried out below.
Why the present invention improves luminous efficiency reason is:
OLED pixel imaging of the present invention is used to show in the process of the light of particular color (wave band), because the first sub-pixed mapping in each sub-pixed mapping group of the present invention and the second sub-pixed mapping share a drive circuit, then only select a sub-pixed mapping in each sub-pixed mapping group to carry out luminescence, that is the present invention select three kinds of sub-pixed mapping and carry out work from six kinds of sub-pixed mapping.Further, because the first sub-pixed mapping in each sub-pixed mapping group of the present invention and the second sub-pixed mapping share a drive circuit, therefore the area ratio of circuit part in OLED pixel is made to reduce, thus improve the ratio of OLED pixel efficient lighting area, be conducive to the size reducing pixel in OLED display panel, to improve the resolution of OLED display panel of the present invention.
In the present embodiment, as shown in Figure 1, six kinds of sub-pixed mapping of OLED pixel 100 are divided into RGB imaging system (comprising R sub-pixed mapping 11, G sub-pixed mapping 21 and B sub-pixed mapping 31) and CMY imaging system (comprising C sub-pixed mapping 12, M sub-pixed mapping 22 and Y sub-pixed mapping 32).
Thus, in the process of light using OLED pixel imaging of the present invention display particular color (wave band), the three kinds of sub-pixed mapping carrying out luminous work all can be selected from RGB imaging system or CMY imaging system, also can select three kinds of required sub-pixed mapping after RGB imaging system combines with CMY imaging system.
Again due to, the composition of white light (W) can be divided into red spectral band (R), green light band (G) and blue wave band (B) three parts, then as previously mentioned, white light is divided into three-beam after light splitting piece, for ruddiness light splitting piece, green glow light splitting piece or blue light light splitting piece, the light (a certain sub-pixed mapping in CMY imaging system) of the centre then after light splitting piece accounts for 2/3 of former white light gross energy, and the light (a certain sub-pixed mapping of RGB imaging system) of the two bundle specific wavelengths separated towards both sides accounts for 1/3 of gross energy altogether.
Thus, in the process of light using OLED pixel imaging of the present invention display particular color (wave band), when the three kinds of sub-pixed mapping carrying out luminous work are all selected from RGB imaging system, then the present invention uses the OLED pixel of filter to have identical luminous efficiency with traditional; But when the three kinds of sub-pixed mapping carrying out luminous work in the present invention are all selected from CMY imaging system, then luminous efficiency of the present invention is then the twice that tradition uses the OLED pixel of filter, in other words, now, the power consumption of OLED pixel of the present invention can reach the half that tradition uses the OLED pixel power consumption of filter.
Owing to invention increases, the C sub-pixed mapping of CMY imaging system, M sub-pixed mapping and Y sub-pixed mapping 3 kinds of sub-pixed mapping are collaborative carries out imaging, thus improve the luminous efficiency of OLED pixel, and then reduction power consumption, in the present invention when ensureing that color saturation is constant, time the most desirable (when only using C sub-pixed mapping, M sub-pixed mapping and Y sub-pixed mapping to carry out luminescence), the power consumption of OLED pixel of the present invention can reach the half that tradition uses the OLED pixel power consumption of filter.
Principle during concrete imaging of the present invention is as follows:
When imaging shows, the luminous intensity data that the luminous intensity data transaction of original RGB tri-look becomes CMY tri-form and aspect corresponding by the present invention, the luminous intensity of corresponding sub-pixed mapping is represented with lowercase, due in the present embodiment, the first sub-pixed mapping in white light OLED luminous element size corresponding in first sub-pixed mapping of each sub-pixed mapping group and the second sub-pixed mapping and each sub-pixed mapping group is all equal with the second sub-pixed mapping size, simultaneously, each light splitting piece is isosceles trapezoid, therefore can obtain the relational expression of following luminous intensity conversion:
c=0.5*（g+b-r）
m=0.5*（g+r-b）
y=0.5*（r+b-g）
Can be known by relational expression above, when utilizing OLED pixel of the present invention to show the light of particular color (wave band):
In the RGB three primary colors of the light of described pre-display, when the luminous intensity of a certain primary colors is less than two other primary colors luminous intensity sum, c, m and y tri-luminous intensity values then after conversion are all greater than 0, so only use CMY imaging system, namely the respective combination of C sub-pixed mapping 12, M sub-pixed mapping 22 and Y sub-pixed mapping 32 is only used, just the light of pre-display wave band can be formed, in other words, if c, m and y tri-luminous intensity values after conversion are all greater than 0, then the light of the particular color of pre-display can well be reduced;
In the RGB three primary colors of the light of described pre-display, when the luminous intensity of a certain primary colors is greater than two other primary colors luminous intensity sum, then have certain value into negative value in c, m and y after changing tri-luminous intensity values.Such as; in the RGB three primary colors of the light of described pre-display; during luminous intensity g sum more than the luminous intensity b of B primary colors and G primary colors of the luminous intensity r of R primary colors; i.e. r>b+g; then c is negative value; now instruction book net income CMY imaging system, namely uses merely the method for the respective combination of C sub-pixed mapping 12, M sub-pixed mapping 22 and Y sub-pixed mapping 32 cannot go out the light of the particular color of pre-display by normal reduction.When the luminous intensity g of luminous intensity b or G primary colors that same problem also appears in B primary colors exceedes the luminous intensity sum of all the other two primary colors.Therefore, when one of c, m and y tri-luminous intensity values are negative value, need to use RGB imaging system, namely R sub-pixed mapping 11, G sub-pixed mapping 21 and B sub-pixed mapping 31 compensates, to ensure the color saturation of the light of the particular color of pre-display.
Such as, in the light for the particular color of pre-display, when the luminous intensity r of required R primary colors is very large (r>b+g), because the angle of aforementioned light on wave band covers meets C=B+G; M=R+B; Y=R+G, therefore utilize M sub-pixed mapping 22 to provide blue light (B) and part ruddiness (R) and utilize after Y sub-pixed mapping 32 provides green glow (G) and part ruddiness (R), due to, required R primary colors is a lot, then also need to use R sub-pixed mapping 11 to provide the ruddiness of extra needs to compensate, to ensure the color saturation of the light of the particular color of pre-display.
