Description
本发明涉及显示技术领域,尤其涉及一种 OLED 显示面板的制作方法及装置。
OLED 显示器是新一代的显示器,通过在 OLED
基板上制作有机薄膜,其中有机薄膜被包夹在阴极和阳极金属或导电层之间,给两电极加电压,则有机薄膜会发光。 OLED
显示器相对于液晶显示器有自发光,响应快,视角广,色彩饱和等许多优点。
空气中的水氧会使 OLED 器件阴极的活泼金属被氧化,以及会与有机材料发生化学反应,这些都会引起
OLED 器件失效。因此, OLED 器件的有效封装,使 OLED 器件与水氧充分隔离,对延长 OLED 器件寿命至关重要。目前, OLED
封装方法主要有:干燥片 +UV 胶,面封装, frit 胶 ( 玻璃胶 ) 封装,薄膜封装等。因 Frit
胶封装具有良好的封装效果,且该封装方法灵活方便,对于不同尺寸产品可灵活应对,因此是一种极具发展的封装方法。
如图 2a 所示,在 frit 胶 203 的封装制程中,因所述 frit 胶 203
起始点有已经固化的凸起 205 ,造成在 N2 环境中盖板 202 与基板 201 贴合过程中,有所述凸起 205
的一边经常无法紧密贴合,无所述凸起 205 的一边可紧密贴合,如图 2b 所示,盖板 211 与基板 210 通过 frit 胶 212 以及 UV 胶
213 紧密贴合。
如图 2a 所示,在激光扫描过程中,因所述盖板 202 四周的一圈 UV 胶 204
已经固化完成,即使激光扫描时,所述 frit 胶 203 会融化后再固化,但已固化的所述 UV 胶 204
会一直固定住这种无法紧密贴合的状态,所以激光扫描后再固化所述 frit 胶 203 也无法紧密的粘黏住所述盖板 202 和所述基板 201
,两者之间还是会存在缝隙;如此,在切割掉四周的所述 UV 胶 204 后,得到所述 frit 胶 203 封装的 OLED
显示面板会密闭性不好,空气中的水氧会从缝隙中进入 OLED 器件内部,导致封装失效。
综上所述,现有技术的 OLED
显示面板的制作方法及装置,对玻璃胶起始点的凸起进行软化再固化的过程中,因玻璃胶四周的一圈 UV 胶已经固化完成,会一直保持这种无法紧密贴合的固定状态,造成在
N2 环境下盖板与基板在有凸起的一侧不能紧密贴合,从而导致 OLED 显示面板的密闭性不好,进而影响封装效果。

胶可暂时性的固定所述封装盖板与所述基板,以及暂时性的隔绝 OLED 器件与外界空气接触。接着在 N2
环境中,将所述封装盖板与所述基板对位贴合,并经过 UV 光照射,将所述 UV 胶固化。所述方法还包括以下步骤:
S101 、将贴合后的 OLED 合板置于所述第一透明压合板与所述第二透明压合板之间,且夹紧所述
OLED 合板;
S102 、用贴合于封装盖板一侧的所述第一透明压合板上方的激光头发射激光束,照射所述 OLED
合板的玻璃胶起始点的凸起位置,并将所述腔体内温度加热至 70 ℃ ~90 ℃;
S103 、所述第一透明压合板与所述第二透明压合板相向运动,对所述 OLED
合板进行压合,直至所述玻璃胶与所述封装盖板紧密贴合;
S104 、完成后将所述 OLED
合板传送至镭射固化机台,进行玻璃胶固化,然后再切割,得到所述玻璃胶封装的各所述显示面板。
在放置所述 OLED
合板时,为所述封装盖板的一面,面向所述激光头放置;当所述凸起软化后,并且所述腔室内温度达到 80 ℃时,所述 UV
胶软化,所述第一透明压合板与所述第二透明压合板进行压合,当所述玻璃胶与所述封装盖板紧密贴合时,停止压合操作,所述第一透明压合板与所述第二透明压合板背离运动,进行后续操作。
相比较现有技术,本发明所提供的一种 OLED
显示面板的制作方法及装置,能使玻璃胶起始点的凸起在软化的过程中,外围一圈 UV 胶也随之软化,利用相对设置的两个透明压合板压合 OLED
合板,使封装盖板与基板能够紧密贴合,从而保证良好的密封性,进而保证封装效果。
综上所述,虽然本发明已以优选实施例揭露如上,但上述优选实施例并非用以限制本发明,本领域的普通技术人员,在不脱离本发明的精神和范围内,均可作各种更动与润饰,因此本发明的保护范围以权利要求界定的范围为准。
