Detailed description of the invention
The present invention provides a kind of display floater suitable in typography and display, and for making the purpose of the present invention, technical scheme and effect clearly, clearly, the present invention is described in more detail below.Should be appreciated that specific embodiment described herein is only in order to explain the present invention, is not intended to limit the present invention.
Refer to Fig. 3, Fig. 3 is a kind of display floater suitable in typography of the present invention, it includes luminous zone 100 and is positioned at the surrounding zone 200 of luminous zone 100 surrounding, surrounding zone 200 arranges the print buffer 210 being connected with luminous zone 100 and the driver circuit bonding pad 220 being connected with print buffer 210, as shown in Fig. 4 or Fig. 5, in described print buffer 210, it is provided with the ink crystallizing field 230 for deposited ink.
The present invention thes improvement is that: arrange print buffer 210 on surrounding zone 200, the edge of such luminous zone 100 will have a relief area for printing, the ink dried environment of the marginal area of such luminous zone 100 will become more consistent with the ink dried environment of the zone line of luminous zone 100, change thus avoiding atmosphere residing for ink, efficiently solve the mura problem of luminous zone frontside edge, improve display floater uniformity of luminance.Additionally, due to be provided with ink crystallizing field 230 in print buffer 210, when deposited ink, ink crystallizing field 230 can effectively control sprawling of ink, it is prevented that ink spreads into driver circuit bonding pad 220, thus simplifying processing technology, reduces cost of manufacture.
As shown in Figure 4, described ink crystallizing field 230 is provided with multiple, and interval is arranged.The formation of ink crystallizing field 230 is similar to pixel hole, and the centre of Jimo water crystallizing field 230 has the deposition for deposited ink to cheat, and utilizes what such multiple ink crystallizing field 230 can effectively control ink to sprawl region, it is to avoid ink spreads into periphery.When arranging multiple ink crystallizing field 230, owing to having multilayer proofing, so ink deposition effect is better, more effective can guarantee that ink will not spread into driver circuit bonding pad 220.
As it is shown in figure 5, described ink crystallizing field 230 is set to 1.When being set to 1, the deposition hole in the middle of this ink crystallizing field 230 is relatively big, and such set-up mode can simplify processing technology, improves make efficiency, and also can ensure that ink is not stuck with paste to a certain extent spreads into driver circuit bonding pad 220 simultaneously.
As shown in Figure 4 and Figure 5, described surrounding zone 200 is additionally provided with the driver circuit bonding pad 220 being connected with print buffer 230, encapsulation region in this driver circuit bonding pad 220 i.e. Fig. 4 or Fig. 5 and circuit draw-out area, owing to the display floater of the present invention is when marking ink, ink can be prevented effectively from and spread into driver circuit bonding pad 220, so without using strip technique to remove the thin film of relevant range, it is to avoid the open circuit problem of relevant range.
In the present invention, the luminescence unit of described luminous zone 100 is the mixed structure of OLED or QLED or OLED and QLED.That is, this luminescence unit both can be organic electroluminescent LED, it can also be light emitting diode with quantum dots, or the mixed structure of organic electroluminescent LED and quantum dot light emitting diode, namely the applicable scope of the display floater of the present invention is wide, especially for needing to use the display floater of typography, owing to film forming is uniform, solve the mura problem of luminous zone frontside edge, so being more suitable for large-area production.Namely preferred, described luminescence unit have at least an one functional layer adopt typography to prepare.
Described luminous zone 100 is the luminescent device of the luminescent device of passive waked-up or driven with active matrix.The type of drive of passive matrix is multichannel dynamic driving, and this type of drive is by the restriction of scan electrode number, and dutycycle coefficient is the important parameter of passive waked-up.And the type of drive of active matrix belongs to static drive mode, it is not by the restriction of scan electrode number, it is possible to each pixel independently carries out selective control.Namely the present invention can be suitable for the luminescent device of various type of drive.
It is provided with in described luminous zone 100 that red, green, blue is trichroism or red, green, blue, white four sub-pixels, specifically can select required sub-pixel according to practical situation.
As shown in Figure 6, it is on the basis of Fig. 5, first defines in pixel and deposited luminescent layer 150 in the pixel hole that layer 130 is formed and in ink crystallizing field 230, then all deposited top electrode 300 in luminous zone 100 and surrounding zone 200.As can be seen from Figure 6, by arranging ink crystallizing field 230 in print buffer 210, the ink crystallizing field 230 that ink only can at most only can be deposited on print buffer 210 to arrange, it is possible to prevent ink to spread into driver circuit bonding pad 220, so without additionally using strip technique to remove the thin film of relevant range, it is to avoid open circuit problem.
The present invention also provides for a kind of display, and it includes display floater as above.
In sum, the present invention by arranging the print buffer being connected with luminous zone on the surrounding zone of display floater, described print buffer is utilized to control the mura problem at edge, luminous zone, make the ink crystallizing field in similar pixel hole at print buffer simultaneously, effectively control sprawling of ink, it is prevented that ink spreads into junction.
It should be appreciated that the application of the present invention is not limited to above-mentioned citing, for those of ordinary skills, it is possible to improved according to the above description or convert, all these improve and convert the protection domain that all should belong to claims of the present invention.
