Embodiment Construction

[0028] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments. In particular, the following examples are only used to illustrate the present invention, but not to limit the scope of the present invention. Likewise, the following embodiments are only some but not all embodiments of the present invention, and all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0029] see figure 1 , figure 1 It is a schematic diagram of the composition and structure of the OLED display module in the prior art. The OLED display module includes a TFT array substrate 11, an OLED light-emitting functional layer 12, a package cover 13, a sealant 15, and a filling gas 14, which is usually an inert gas such as N2. The disadvantage of this structure is that because the filler is gas, and the thermal conductivity of the gas is po...

Abstract

The invention provides an OLED display module and its display. The OLED display module includes: a substrate, an OLED light-emitting unit, and a packaging component; the OLED light-emitting unit is arranged on the upper surface of the substrate substrate; and the packaging component is arranged outside the OLED light-emitting unit ; Wherein, the package assembly further includes a package cover, a package plastic frame, and a mercury filling in a cavity formed by the package cover, package plastic frame and OLED light-emitting unit. Compared with the prior art, the OLED display module and the display provided by the present invention use mercury as the packaging material, and utilize the good thermal conductivity of mercury to dissipate the heat generated by the OLED in time (transfer to the packaging cover), reducing the organic The heat generated by the light-emitting element array when emitting light is conducted to the transistor array, thereby avoiding the phenomenon of uneven display caused by it, thereby prolonging the service life of the OLED and improving the display quality. In addition, it is equivalent to increasing the thickness of the cathode layer to improve its conductivity.

Description

technical field [0001] The invention relates to the technical field of OLED display, in particular to an OLED display module and a display thereof. Background technique [0002] Active-matrix Organic Light-Emitting Diode (AMOLED), as a new generation display technology, has the advantages of low power consumption, small size, high color gamut, wide viewing angle and fast response. However, since AMOLED is driven by current, if the heat generated by the OLED is not dissipated in time during the lighting process, the temperature of the backplane will easily rise, which will affect the performance of the backplane, resulting in a decrease in display brightness and shortened life. unevenness etc. Therefore, the heat dissipation of AMOLED determines the picture quality and service life of the display. Contents of the invention [0003] Embodiments of the present invention provide an OLED display module and a display thereof, so as to solve the technical problems of poor heat ...
