Embodiment Construction

[0055] Next, an embodiment of a droplet ejection device that performs pattern drawing processing based on ejection pattern data corrected by the ejection pattern data correcting method of the present invention will be described with reference to the drawings. This droplet ejection device is incorporated in the production line of the flat panel display, and the color filter and the An organic EL device serves as a light emitting element of each pixel, and the like.

[0056] As shown in FIG. 1 , a liquid droplet ejection device 1 has a base 2, a pattern drawing device 3 mounted on the entire area of ​​the base 2 and equipped with a functional droplet ejection head 17, and a base 2 on the base 2. The maintenance device 4 provided in the pattern drawing device 3 is added, and the maintenance process (function maintenance and recovery) of the functional droplet ejection head 17 is performed by the maintenance device 4, and the function liquid is discharged onto the substrate W by t...

Abstract

A method of correcting ejection pattern data comprises the steps of: calculating an amount of function liquid given in the drawing processing to each of a plurality of imaginary divided portions obtained by partitioning into matrix a drawing region on the workpiece; generating matrix data which represents in multi-valued gradation an amount of function liquid given to the plurality of imaginary divided portions; processing gradation by converting the matrix data into n-valued data to thereby generate n-valued matrix data, where n is an integer equal to or larger than 2; and correcting ejection pattern data so as to perform at least one of decreasing and increasing the amount of function liquid given to the imaginary divided portions, the amount being decreased where each of the n-valued data of the n-valued matrix data represents the side of 'large,' and the amount being increased where each of the n-valued data of the n-valued matrix data represents the side of 'small,' respectively, in the amount of function liquid given to the imaginary divided portions.

Description

technical field [0001] The present invention relates to an ejection pattern data for performing pattern drawing processing by selectively ejecting functional liquid droplets from a plurality of nozzles of a functional liquid droplet ejection head typified by an inkjet head, respectively. Disclosed are a discharge pattern data correction method, a discharge pattern data correction device, a droplet discharge device, a manufacturing method of an electro-optical device, an electro-optical device, and an electronic device. Background technique [0002] Conventionally, there is known a liquid droplet ejection device that, based on the ejection pattern data, sends a color filter (workpiece) with colored portions arranged in a plurality of rows, from an inkjet head (a functional liquid droplet ejection head) to ) ink ejection nozzles (nozzles) eject ink (functional liquid) to perform pattern drawing processing. Since the amount of ink ejection is not uniform among a plurality of i...
