Description

Method for producing liquid crystal display

[technical field]

The invention relates to a kind of method for producing liquid crystal display, and particularly relevant for a kind of manufacture method of before display panels is separated from one another, just finishing the LCD of Polarizer attaching step.

[background technology]

Please refer to the 1st figure, it illustrates the process flow diagram of the method for producing liquid crystal display that is tradition.In step 11, provide a panel to the group structure.If with liquid crystal drop-method (one dropfill, ODF), this panel comprises one of be arranged in parallel upper substrate and an infrabasal plate and several frame glue and several liquid crystal to the group structure, frame glue is to connect surface within upper substrate and the infrabasal plate, and each liquid crystal is to be filled between each frame glue, upper substrate and the upper substrate.Upper substrate includes several colored filter substrates, infrabasal plate includes several thin film transistor base plates corresponding to colored filter substrate, and each colored filter substrate, each thin film transistor base plate, each frame glue and each liquid crystal are to constitute a display panels.

If with liquid crystal vacuum inhalation (liquid crystal injection), this panel comprises one of be arranged in parallel upper substrate and an infrabasal plate and several frame glue to the group structure, frame glue is to connect surface within upper substrate and the infrabasal plate, and each colored filter substrate, each thin film transistor base plate and each frame glue are the panels that formation one waits to irritate liquid crystal.

Then, enter in the step 12, with flywheel knife cutting upper substrate and infrabasal plate, and parting liquid LCD panel or wait to irritate the panel of liquid crystal.At this moment, for each panel of waiting to irritate liquid crystal, can liquid crystal be poured into the panel that each waits to irritate liquid crystal via the liquid crystal injecting port of frame glue, and after having irritated liquid crystal, liquid crystal injecting port be sealed, finish at this via the display panels of liquid crystal injection method.

Then, enter in the step 13, carry out the edging and the lead angle step of the thin film transistor base plate of each display panels with emery wheel.Mainly be to carry out edging at two edges that pin extended to outside the thin film transistor base plate to handle, and being carried out lead angle, the part corner of thin film transistor base plate handles, the edge of avoiding thin film transistor base plate is too sharp keen and influence subsequent wafer and see through glutinous brilliant method (the chip on glass of glass, COF) and external circuit, the step of a circuit board electric connection for example, or the packaging part that contains wafer (or is called winding carrier packaging part (tape carrier package, TCP)), or one flexible circuit plate (FPC) see through the automatic bonding method of winding (tape automatic bonding, TAB), and then cause the phenomenon of thin film transistor base plate and external circuit poor electrical contact with the step of outer pin electric connection.Especially at flexible circuit plate (flexible circuit board, FPC) or packaging part (TCP) during with the electric connection of outer pin, if do not carry out the edging and the lead angle step of thin film transistor base plate earlier, will be very easy to take place the flexible circuit plate to be cut bad and the phenomenon of damages causes the yield decline of LCD by the glass sharpened edge of thin film transistor base plate or corner.

Then, enter in the step 14, because emery wheel can produce a large amount of particle, powder or foreign matter after edging that carries out thin film transistor base plate and lead angle step, so must clean each display panels and scrape the universe by water, to keep the clean of display panels, can carry out next step.Then, enter in the step 15, attaching Polarizer and Polarizer down on the surface outside the colored filter substrate of each display panels and the thin film transistor base plate accordingly, the light penetrating shaft of last Polarizer for example is vertical with the light penetrating shaft of following Polarizer.Then, enter in the step 16, electrically contact with pin outside a test card and each display panels seriatim and pour into test signal, the operating personnel can observe the picture quality of each display panels in by irradiation the time.Usually can will seriatim each display panels be written into a robotic arm/carry (load/unload) on tester table; electrically contact with the outer pin of display panels on being positioned at tester table with test card again and pour into test signal; the operating personnel can observe the picture quality of each display panels in by irradiation the time, carry out remedial measures to choose the bad display panels of demonstration.The display panels that passes through as for other and lattice is with continuing to be sent to next technology station, to test the next step of back.

Then, enter in the step 17, carry out the COG or the TAB step of each display panels.In COG, wafer is can see through the anisotropy conducting film (anisotropicconductive film ACF) electrically connects with outer pin, and outer pin connects through flexible circuit plate and external circuit electricity again.In TAB, or the packaging part (TCP) that contains wafer is can see through ACF to electrically connect with outer pin, and FPC can see through ACF to electrically connect with packaging part, make FPC see through packaging part and the electric connection of outer pin.Then, enter in the step 18, assembling display panels and module backlight are to constitute LCD.

Yet, in step 13, carry out the edging of thin film transistor (TFT) and the design of lead foot step traditionally with emery wheel, be easy to generate particle, powder or foreign matter, so must in step 14, clean each display panels and scrape the universe by water, cause processing step to become more and loaded down with trivial details, and the dealer will spend many production costs and purchase abrasive machine, cleaning machine and scrape machinery and equipment such as universe machine.If it is clean that particle, powder or foreign matter are not eliminated, then display panels easily produces the phenomenon of defective because of being stained with glutinous powder, particle or foreign matter.

In addition, if in step 14, display panels is not scraped the universe, then in step 15, be easy to generate Polarizer and attach not firm phenomenon.Even can remain in the phenomenon that causes Newton ring or washmarking outside the display panels on the surface because of water droplet, this all can influence the picture quality of LCD.

In addition, if big panel can be cut into 502 small sizes (as 1.2 inches to the group structure, be 620mm*750mm) display panels the time, if will finish from the Polarizer attaching and the test card test action of panel to each display panels of separating of group structure, the Polarizer that then will carry out 502 times in step 15 attaches action, and also will carry out 502 times robotization be written into/carry the test action that goes out to move with the test card that carries out each display panels in step 16.Thus, the test duration that causes finishing attaching time of Polarizer of 502 display panels and test card all can be quite tediously long, and the technology of the whole LCD that seems is quite inefficent, does not meet economic benefit.
