Problems solved by technology

In this way, in the case of non-discharging nozzles in the blocks 53b and 53c, if two drops are to be ejected, it may be applied outside the block, or the specified amount of liquid droplets may not be sprayed in the block, or mixed with To other blocks, etc., there are problems that cause defective blocks and mixed colors to emit light

Embodiment approach 1

[0129] Next, Embodiment 1 of the present invention will be described.

[0130] Figure 6 It is a conceptual diagram of the ink application device in Embodiment 1. Figure 7 In the case of printing with this ink application device, the application image 3 that two-dimensionally marks the ink ejection position and non-ejection nozzle information of the used nozzles are shown.

[0131] In this example, there are nine blocks 1c, and each block 1c is filled with a necessary amount of ink for three drops of ejection. The black circle is the spraying position, and the white circle is the non-spraying position.

[0132] Figure 7 The coating image 3 of is constituted by a two-dimensional coordinate system of the arrangement direction of the nozzles (row direction Y) and the scanning direction of the nozzles (column direction X). In the coating image 3, the dots at which ink should be ejected from the nozzles are connected by dotted lines to form a grid. The intersection point bec...

Embodiment approach 2

[0227] In Embodiment 2, the case of spraying to different types of panels will be described. Items not described are the same as those in Embodiment 1.

[0228] Figure 15 (a) is a plan view of a substrate 40 in which two types of display panels coexist, which is the object of the second embodiment. On the substrate 40, three small display panels 41a to 41c are arranged on the left side, and a large display panel 42 is arranged on the right side. 2k panels of 300 ppi are arranged on the small display panels 41a to 41c. A 4k panel of 200ppi is arranged on the large display panel 42 . As a result, blocks 1c of 300ppi and 200ppi are placed in the respective panel areas.

[0229] Figure 15(b) shows the positional relationship of ink ejection in the up-down direction (scanning direction, X direction) between the first block 1c of the small display panels 41a to 41c and the block 1c of the large display panel 42 .

[0230] In the block 1c of the small display panel 41a, ink i...

Abstract

The present invention provides an ink application device and an ink application method capable of ejecting a specified number of droplets without exceeding a block even when the size of the block in the column direction X is shortened. The ink application device of utilization has: ejection head, ejects ink from a plurality of nozzles; Stand, keeps coating object; Ejection timing holding part, the ejection timing of output standard; No-ejection nozzle data part, stores the number of non-ejection nozzles. position; a nozzle direction ejection number information section that holds nozzle direction ejection number information based on the application image; and a control section that drives the The head is configured to discharge the ink a plurality of times before and after the discharge timing of the other discharge nozzles from the nozzle capable of applying to the same block as the non-discharge nozzle.

Description

technical field [0001] The present invention relates to an ink application device and an ink application method. In particular, it relates to a light-emitting layer of a display panel for a display device such as organic EL (ElectroLuminescence), and an ink application device equipped with an inkjet head and an ink application method used in other application processes. Background technique [0002] As a method of forming the organic light-emitting layer of an organic EL display panel, there is a method of applying a low-molecular organic material or a high-molecular organic material together with a solvent. One of the typical methods of forming an organic light-emitting layer by applying a solvent includes a method of discharging ink droplets containing an organic light-emitting material onto a segment of a display substrate using an ink application device. At this time, the ejected ink droplets contain the organic light-emitting material and the solvent. [0003] A gener...
