Abstract

The invention discloses a huge transfer carrier plate, a huge transfer device and a huge transfer method. The huge transfer carrier plate comprises a temperature control device, a telescopic plate located on the temperature control device and a first adhesive layer arranged on the telescopic plate. The temperature control device is used for controlling the temperature of the telescopic plate, andthe telescopic plate is used for stretching out and drawing back according to temperature changes so as to adjust the distance between the micro devices attached to the first adhesive layer. In the mass transfer process; the micro device is adhered to the telescopic plate through the first adhesive layer; when the distance between the micro devices needs to be adjusted, the temperature of the telescopic plate can be adjusted through the temperature control device, the telescopic plate can be stretched or contracted under the influence of temperature changes, and therefore the distance betweenthe micro devices adhering to the telescopic plate is driven to be increased or decreased, and the distance between the micro devices is adjusted in the further large-scale transferring process.

Description

technical field [0001] The invention relates to the technical field of mass transfer, in particular to a carrier plate for mass transfer, a mass transfer device and a method thereof. Background technique [0002] Micro-device technology refers to an array of micro-sized components integrated at high density on a driver circuit board. At present, micro-pitch light-emitting diode (Micro-LED) technology has gradually become a research hotspot. Micro-LED technology, that is, LED miniaturization and matrix technology, has good stability, lifespan, and advantages in operating temperature. It also inherits the LED has the advantages of low power consumption, color saturation, fast response, strong contrast, etc. Micro-LED has higher brightness and lower power consumption. [0003] In the prior art, the pitch of the micro-device is usually adjusted according to the needs. Due to the large number and small size of the micro-device, it is difficult to adjust the pitch of the micro-de...
