Problems solved by technology

However, the theoretical value and the actual measurement value of the coating speed and coating pressure will be different due to the delay of the control signal generated when the sealant is actually applied, etc.
[0020] Therefore, since the coating speed distribution curve does not coincide with the coating pressure distribution curve, there is a problem that the line width and cross-sectional area of ​​the sealant pattern 1 cannot be precisely controlled.

Abstract

The invention discloses a method for setting coating conditions of coaters and a coater using the method. The coater is equipped with a nozzle for discharging sealants by using the coating pressure. The coater coats linear portions of the sealants at a uniform coating speed, and coats corner portions of the sealants at a coating speed with deceleration intervals and acceleration intervals. The method for setting coating conditions of coaters comprises obtaining the coating speed distribution curve, measuring the coating pressure distribution curve, and making the coating pressure distribution curve and the coating speed distribution curve consistent.

Description

technical field [0001] The present invention generally relates to a method of setting coating conditions of a coater and a coater using the method, and more particularly, to an arrangement capable of forming a sealant pattern having a completely uniform line width and a completely uniform cross-sectional area A method of coating conditions of a coater and a coater using the same. Background technique [0002] LCD (Liquid Crystal Display), a type of flat panel display device, is configured to display desired Image. [0003] The LCD includes a liquid crystal layer between a thin film transistor (hereinafter referred to as "TFT") substrate formed with a plurality of pixel patterns and a color filter substrate formed with color filters, and when a signal is applied thereto, the The liquid crystal layer determines whether to transmit light. [0004] In addition, the TFT substrate and the color filter substrate are sealed with a sealant located on their outer bands. [0005] T...
