Problems solved by technology

As the size of the product increases, the number of pixels in the plane increases significantly. On the one hand, it increases the heat accumulation when the pixels emit light. On the other hand, the heat dissipation in the screen gradually deteriorates, resulting in more and more heat accumulation in the screen, and the temperature gradually rises. High, which in turn leads to changes in the properties of the luminescent material, defects such as local yellowing, darkening of the periphery, and overall brightness attenuation in the screen, and even damage to the external control circuit IC and other auxiliary components, and the quality of the product is damaged. A major obstacle to the marketization of AMOLED

preparation example Construction

[0045] figure 2 is a schematic block diagram of a process for preparing an OLED display panel according to an embodiment of the present invention. refer to figure 2 , the process of preparing an OLED display panel may include: preparing a first substrate, wherein the first substrate may be the first substrate 101 as described in the foregoing embodiments, and those skilled in the art have mastered its preparation method, so its specific formation The process will not be repeated here.

[0046] In one embodiment, the step of preparing the first substrate more specifically includes forming scan lines extending along a first direction and data lines extending along a second direction perpendicular to the first direction. The scan lines are formed on the first substrate and extend in a first direction (eg, a horizontal direction). The data lines are formed on the first substrate and extend in a second direction (eg, a vertical direction) perpendicular to the first direction. ...

Abstract

The present invention relates to an organic light emitting diode (OLED) display panel, an OLED display and an OLED unit. Wherein, the OLED display panel includes: scan lines extending along a first direction; data lines extending along a second direction perpendicular to the first direction; OLED units including first electrodes, second electrodes, and formed on the an organic light-emitting layer between the first electrode and the second electrode; and a heat conduction layer formed of an insulating heat conduction material, connected to the scan line, the data line, and the first electrode in the OLED unit. According to the present invention, the heat dissipation of the OLED can be improved, thereby avoiding problems such as luminous chromaticity shift, luminous efficiency reduction, product attenuation and the like caused by OLED heat generation.

Description

technical field [0001] The invention relates to the field of organic light emitting technology, more specifically, the invention relates to an OLED display panel with improved heat dissipation efficiency, a preparation method thereof, and an OLED display. Background technique [0002] With the vigorous development of the display industry, the active matrix organic light-emitting diode (AMOLED) display has the advantages of thinner and lighter, active light emission (no backlight required), no viewing angle problem, high definition, high brightness, fast response, low energy consumption, and low operating temperature. Wide range, strong shock resistance, and soft display can be realized, which are increasingly favored by the market. Under the current technical conditions, luminescent materials are extremely susceptible to the influence of temperature, the luminous chromaticity is seriously shifted, the luminous efficiency is greatly reduced, and the product life will also rap...
