Abstract
The invention provides a flexible display panel. The flexible display panel comprises an OLED display screen and display screen driving ICs. The display screen driving ICs are connected with the OLED display screen trough a flexible printed circuit board. In a normal state, the length direction of the display screen driving ICs is perpendicular to the edges, where the display screen driving ICs are located, of the OLED display screen. The flexible printed circuit board is a TCP or a COF. The flexible display panel comprises the multiple display screen driving ICs which are arranged on the two adjacent edges of the OLED display screen, and the length direction of the display screen driving ICs is perpendicular to the edges, where the display screen driving ICs are located, of the OLED display screen. The flexible display panel has the advantages that the installation direction of the display screen driving ICs is changed, so that the conflict between the length direction of easy breakage and the normal-state bending direction of the display panel is avoided, and a driving method which enables defects and damage of the flexible display screen to be avoided is realized.
Description
Technical field
The invention belongs to plane display technique field, be specifically related to a kind of flexible display panels.
Background technology
Flexible display panels (display) is to be made by soft material, the flexible display device of changeable type.There is low-power consumption, volume is little and the feature such as direct visual flexibility, applies to portable electric appts, pen and touch equipment such as input grade.It is frivolous that flexible touch screen technology can stimulate some Ke Shi armies and other terminal user to use, and the very-low-pover displays that can read under sunlight is inputted, and stores or transmit from remote location the application of instant data.
Light and drive flexible display screen and the flexible product needed drive IC that shows.Be generally to paste after drive IC on the TCP of fexible film and COF film, binding panel is used.As shown in Figure 1, Figure 2 and Figure 3, Fig. 1 is existing drive IC mounting structure schematic diagram, in Fig. 2 (a) and (b) be respectively in Fig. 1 upward view and the bend fracture schematic diagram of below drive IC; In Fig. 3 (a) and (b) be respectively right view and the bend fracture schematic diagram of right-hand drive IC in Fig. 1.Can find out, drive IC, in order to simplify pin wiring and size of display panels, has adopted conventionally along the setting of display panel edge direction.Because drive IC has certain geometrical length, according to existing installation method, although can simplify the wiring of IC circuit, but pasted the flexible display screen panel of drive IC along with self bends, even if drive IC also can be thereupon crooked, if but crooked curvature and crooked power become large, in the process bending, cause damaged problem thereby there will be drive IC to break/rupture.
Summary of the invention
The object of the invention is to have adopted along the setting of display panel edge direction in order to simplify pin wiring and size of display panels in order to solve the drive IC of existing flexible display panels, the deficiency that causes drive IC easily in use to be fractureed and damage, has proposed a kind of flexible display panels.
Technical scheme of the present invention is: a kind of flexible display panels, comprise OLED display screen and display screen drive IC, display screen drive IC is connected with OLED display screen by flexible PCB, it is characterized in that, under normality, the OLED display screen edge at the length direction of drive IC and drive IC place is perpendicular.
Further, above-mentioned flexible PCB is TCP or COF.
Further, flexible display panels comprises a plurality of drive IC, is arranged at respectively the adjacent both sides of OLED display screen, and the length direction of drive IC is respectively perpendicular to the limit at the OLED display screen place at place.
Beneficial effect of the present invention: flexible display panels of the present invention is by changing the installation direction of drive IC, avoid the length direction of easily being lost to conflict mutually with the normality bending direction of display panel, can avoid flexible display screen generation defect and damaged driving method.
Accompanying drawing explanation
Fig. 1 is the structural representation that existing flexible display panels is installed drive IC;
In Fig. 2 (a) and (b) be respectively in Fig. 1 upward view and the bend fracture schematic diagram of below drive IC;
In Fig. 3 (a) and (b) be respectively right view and the bend fracture schematic diagram of right-hand drive IC in Fig. 1;
Fig. 4 is the structural representation that flexible display panels of the present invention is installed drive IC;
Fig. 5 is another specific embodiment of the present invention.
Embodiment
Embodiments of the invention are that principle according to the present invention designs, and below in conjunction with accompanying drawing and specific embodiment, the invention will be further elaborated.
Embodiment 1:
As shown in Figure 4, the flexible display panels of the present embodiment comprises OLED display screen and display screen drive IC, display screen drive IC is connected with OLED display screen by flexible PCB, and under normality, the OLED display screen edge at the length direction of drive IC and drive IC place is perpendicular.Wherein flexible PCB is TCP or COF.
Embodiment 2:
As shown in Figure 5, the flexible display panels of the present embodiment comprises a plurality of drive IC, is arranged at respectively the adjacent both sides of OLED display screen, and the length direction of drive IC is respectively perpendicular to the limit at the OLED display screen place at place.
The circuit-mode that forms connection electric signal in flexible display screen is that the lead-in wire layout by revising in drive IC couples together again.Like this, even crooked flexible display screen up and down, adhering to the drive IC of pasting on the screen of fexible film can be not damaged yet, simultaneously flexible display screen and flexiblely show that bending more can occur product and reliability also can improve.
And as Fig. 5, the fexible film that has adhered to a plurality of drive IC sticks on screen above, flexible display screen and flexible demonstration product can be driven.Even if crooked flexible display screen can not destroy drive IC yet up and down, it is the method that improves product reliability.
Those of ordinary skill in the art will appreciate that, embodiment described here is in order to help reader understanding's principle of the present invention, should be understood to that protection scope of the present invention is not limited to such special statement and embodiment.Those of ordinary skill in the art can make various other various concrete distortion and combinations that do not depart from essence of the present invention according to these technology enlightenments disclosed by the invention, and these distortion and combination are still in protection scope of the present invention.
Claims (3)
1. a flexible display panels, comprise OLED display screen and display screen drive IC, display screen drive IC is connected with OLED display screen by flexible PCB, it is characterized in that, under normality, the OLED display screen edge at the length direction of drive IC and drive IC place is perpendicular.
2. flexible display panels according to claim 1, is characterized in that, flexible PCB is TCP or COF.
3. flexible display panels according to claim 1 and 2, is characterized in that, flexible display panels comprises a plurality of drive IC, is arranged at respectively the adjacent both sides of OLED display screen, and the length direction of drive IC is respectively perpendicular to the limit at the OLED display screen place at place.
