Problems solved by technology

[0011] On the basis of fully analyzing and researching the various technical difficulties faced by the technology of manufacturing large-size full-color OLED displays by splicing standard display modules in the past, the present invention aims to solve the problem of light-emitting pixels caused by the excessive width of the encapsulation side of standard display modules. To solve the problem of wide distance between them, a new light-emitting device panel packaging process and drive unit assembly technology are creatively provided. The standard display module manufactured by this technology has the characteristics of high display accuracy, narrow packaging edge, and high yield rate. The standard display module can be arbitrarily assembled into display screens of various sizes, making OLED technology enter the field of indoor high-end large-size display applications

Embodiment

[0054] like Figure 1~Figure 3 As shown, the OLED display unit mainly includes two parts: a light-emitting device panel 1 and a packaging substrate 3. The light-emitting device panel 1 is provided with electrode terminals 2, and the positions on the packaging substrate 3 corresponding to the electrode terminals 2 are one-to-one. Through-holes 4 are processed, one side of the package substrate 3 is bonded to the side of the light-emitting device panel 1 provided with the electrode terminals 2, and the surroundings of the package substrate 3 and the light-emitting device panel 1 are bonded and packaged together. Conductive substances are poured into the through holes 4 and led to the other side of the packaging substrate 3 to form display unit electrodes 5, which are connected and connected to the electrode terminals 2 on the display substrate in one-to-one correspondence. The display unit electrodes 5 are used for Connect with drive control unit.

Abstract

The invention relates to an organic light emitting diode (OLED) display unit and an OLED display device adopting the OLED display unit. The OLED display unit comprises a luminous device panel and an packaging substrate and is characterized in that electrode terminals are arranged on the luminous device panel; penetration holes which are in one-to-one correspondence to the electrode terminals are formed in the packaging substrate; one face of the packaging substrate is attached to the face (provided with the electrode terminals) of the luminous device panel; the packaging substrate is adhered to and packaged with the periphery of the luminous device panel; conductive substances are filled into the penetration holes in the packaging substrate and are leaded to the other face of the packaging substrate to form display unit electrodes; the display unit electrodes are connected and conducted with electrode terminals on a display substrate in a one-to-one correspondence manner; and the display unit electrodes are connected with a driving control unit. Display devices with various sizes can be assembled; spliced joints between standard display modules in the display device are greatly reduced; the precision of the display device is improved; and a good vision effect is achieved.

Description

technical field [0001] The invention relates to an OLED display unit and a display device using the OLED display unit, and belongs to the technical field of display manufacturing. Background technique [0002] With the rapid development of the electronics industry and the continuous improvement of society's requirements for information display products, indoor or There is a huge market demand for semi-indoor large-scale flat-panel display products.
