Embodiment

Hereinafter with reference to relevant drawings, the improvement method according to the touch-control fixed test of preferred embodiment of the present invention is described, to be convenient to understand for making, the similar elements among the following embodiment illustrates with identical symbology.See also its flow chart of steps for the improvement method of touch control apparatus fixed point test of the present invention of Fig. 1, its steps flow chart is as follows:

Step 11: provide a plurality of correct with reference to coordinate values;

Step 12: produce the first fixed point coordinate values;

Step 13: judge that whether the correct error with reference to coordinate values that the first fixed point coordinate values abuts with it is preset in the error range one, if then carry out step 131, then returns step 12 if not;

Step 131: store the first fixed point coordinate values;

Step 14: produce the second fixed point coordinate values;

Step 15: whether the error of judging the second fixed point coordinate values and the first fixed point coordinate values exists, if then return step 12, if not, then carry out step 151; And

Step 151: confirm the first fixed point coordinate values.

The wherein above-mentioned first fixed point coordinate values and the second fixed point coordinate values be utilize a writing pencil to click a liquid crystal display module (LIQUID CRYSTAL DISPLAY MODULE LCM) produces.In addition, the first fixed point coordinate values is to utilize writing pencil to click a plurality of default coordinate that the liquid crystal display module is produced, and the second fixed point coordinate values is to click a plurality of lattices of LCD MODULE as a proving program.

See also Fig. 2 A to Fig. 2 D, it is the embodiment synoptic diagram of the generation first fixed point coordinate values of touch control apparatus fixed point test improvement method of the present invention.Among the figure, by Fig. 2 A to Fig. 2 D, be at the default respectively cross coordinate 21 in four corners of LCD MODULE 20, cross coordinate 22, cross coordinate 23 and cross coordinate 24, at first utilize writing pencil during operation, click cross coordinate 21, cross coordinate 22, cross coordinate 23 and cross coordinate 24 centers in each corner, can produce the corresponding first fixed point coordinate values of each the default coordinate values that abuts with it, and will preset coordinate values first fixed point coordinate values pairing and do a comparison with it, if error between the two in a default error range, promptly stores the first fixed point coordinate values.Otherwise, if error between the two not in default error range, then repeats to produce the first fixed point coordinate values, thus, the first fixed point coordinate values that can guarantee to produce does not need follow-up test to find operate miss within the scope that error allows, again whole again flow process, and cause damage.

See also Fig. 3, it is the embodiment synoptic diagram of the generation second fixed point coordinate values of touch control apparatus fixed point test improvement method of the present invention.Because in the fixed test program of touch control apparatus fixed point test improvement method, the unavoidable error that takes place, so after producing the first fixed point coordinate, LCD MODULE 20 promptly shows a plurality of lattices, wherein the part lattice shows anti-white, the test zone 31 that this a little lattice combined is as a proving program.After the tester clicks anti-white part lattice in the LCD MODULE 20, LCD MODULE 20 is according to position that the tester clicked, produce the second fixed point coordinate, if in proving program, with the first fixed point coordinate and the second fixed point coordinate comparison, find that the second fixed point coordinate does not have the result of skew or error, the first fixed point coordinate values can be confirmed as certain value.

But because in proving program, a plurality of lattices in the hit testing zone 31 only are so it is very big that the probability of error takes place, if will can lose time each lattice hit testing all again.Behind each proving program, the coordinate of gained is really in error range, do not need a lot of proving programs again, so before will storing the fixed point coordinate values of being tried to achieve at every turn, must in the fixed point program, add judgement to the correctness of gained coordinate values, result by proving program judges that the work that continues is the continuation operation, reorientates or store the fixed point coordinate values.

The above; it only is preferred embodiment of the present invention; be not that the present invention is done restriction on any type of; though the present invention discloses as above with a preferred embodiment; right its is not in order to limiting the present invention, anyly is familiar with present technique field person, without departing from the spirit and scope of the present invention; when can being used for a variety of modifications and variations, so protection scope of the present invention defines and is as the criterion when looking accompanying claim.
