下面结合附图并通过具体实施方式来进一步说明本发明的技术方案。The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

一种提高产品质量的电子显示屏生产工艺,包括以下步骤:A production process of an electronic display screen for improving product quality, comprising the following steps:

S1)配置清洁剂并添加至等离子清洗机,并使用等离子清洗机清洗来料检验合格的ITO玻璃;S1) Configure a cleaning agent and add it to the plasma cleaning machine, and use the plasma cleaning machine to clean the ITO glass that has passed the inspection of incoming materials;

S2)采用水滴接触角测试仪检测经过清洗的ITO玻璃,检测并确认该批次清洗的ITO玻璃的水滴接触角是否达到质量控制标准,若是则执行步骤S3),否则调整清洁剂的成分配比并重复执行步骤S1);S2) Use a water drop contact angle tester to detect the cleaned ITO glass, detect and confirm whether the water drop contact angle of the ITO glass cleaned in this batch meets the quality control standard, if so, perform step S3), otherwise adjust the composition ratio of the cleaning agent And repeat step S1);

其中,按照重量百分比计算,所述清洁剂包括石油醚10-30%和无水乙醇70-90%。Wherein, the cleaning agent includes 10-30% of petroleum ether and 70-90% of absolute ethanol, calculated by weight percentage.

图1所示的使用本发明的所述提高产品质量的电子显示屏生产工艺的LCD显示屏实施例的工艺流程图。Figure 1 is a process flow diagram of an embodiment of an LCD display screen using the electronic display screen production process for improving product quality of the present invention.

本发明的所述提高产品质量的电子显示屏生产工艺,采用清洁剂清洗ITO玻璃的表面,并以检测水滴接触角的方式控制清洗ITO玻璃的质量,然后通过以水煮实验和高温高湿实验作为检测手段来确认电子显示屏制品无气泡,由此提高电子显示屏的贴附质量,继而减少产品输出后的显示不良的客户投诉率。The electronic display screen production process for improving product quality of the present invention uses a cleaning agent to clean the surface of the ITO glass, and controls the quality of the cleaned ITO glass by detecting the contact angle of water droplets, and then passes the water boiling experiment and the high temperature and high humidity experiment. It is used as a detection method to confirm that there are no air bubbles in electronic display products, thereby improving the attachment quality of electronic display screens, and then reducing the customer complaint rate of poor display after product output.

所述清洁剂采用无水乙醇为稀释液,以提高石油醚清洁ITO玻璃的效果;如若石油醚的含量超过30wt%,容易导致清洗后的ITO玻璃的导电膜的表面有残留的石油醚,残留的石油醚对LCD导电线路有一定的侵蚀作用,继而导致使用过程中贴附的ITO玻璃的导电膜下方出现气隙缺陷,存在使用石油醚的含量为31-35wt%时电子显示屏在水煮实验和高温高湿实验中不会出现气泡现象,因而无法检测发现,影响电子显示屏后期的使用质量,从而导致客诉率超过500ppm。Described cleaning agent adopts absolute ethanol as diluent, to improve the effect of sherwood oil cleaning ITO glass; If the content of sherwood oil exceeds 30wt%, easily cause the surface of the conductive film of the ITO glass after cleaning to have residual sherwood oil, residual The petroleum ether has a certain erosive effect on the conductive lines of the LCD, which in turn leads to air gap defects under the conductive film of the attached ITO glass during use. When the content of petroleum ether is 31-35wt%, the electronic display screen is boiled There will be no air bubbles in the experiment and the high temperature and high humidity experiment, so it cannot be detected and found, which affects the quality of the electronic display in the later stage, resulting in a customer complaint rate of more than 500ppm.

进一步的,步骤S1)前还包括:步骤S0)抽样检测来料的ITO玻璃的表面有无油污,如发现ITO玻璃的表面有油污,则整批退货。Further, before step S1), it also includes: step S0) to sample and inspect whether there is oil stain on the surface of the incoming ITO glass, and if oil stain is found on the surface of the ITO glass, return the whole batch.

采用显微镜,在放大100倍的情况下检测料的ITO玻璃表面,避免使用油污污染了的ITO玻璃而影响电子显示屏的生产质量。Use a microscope to detect the ITO glass surface of the material under magnification of 100 times, so as to avoid the use of ITO glass polluted by oil and affect the production quality of electronic display screens.

具体的,步骤S2)中,质量控制标准为水滴接触角≤20°,检测ITO玻璃的水滴接触角的频率为批次首样5pcs全捡和每隔2小时抽检5pcs。Specifically, in step S2), the quality control standard is that the water drop contact angle is ≤ 20°, and the frequency of testing the water drop contact angle of the ITO glass is 5 pcs of the first sample of the batch, and 5 pcs of random inspection every 2 hours.

水滴接触角测试的接触角大,表示ITO玻璃的表面被憎水性的污物(油/脂等)污染,反之,接触角小,液滴破裂或摊薄,则表示该表面较为洁净。本发明定义水滴接触角≤20°的ITO玻璃的洁净度达标。The large contact angle of the water droplet contact angle test indicates that the surface of the ITO glass is polluted by hydrophobic dirt (oil/grease, etc.). On the contrary, the small contact angle and the droplet rupture or thinning indicate that the surface is relatively clean. The invention defines that the cleanliness of the ITO glass whose water drop contact angle is less than or equal to 20° reaches the standard.

进一步的,所述步骤S2)和S3)之间还包括以下步骤:Further, the following steps are also included between the steps S2) and S3):

S2.1)如检测发现ITO玻璃的水滴接触角不满足质量控制标准,则判定已清洗的ITO玻璃不合格;S2.1) If the water drop contact angle of the ITO glass does not meet the quality control standard, it is determined that the cleaned ITO glass is unqualified;

S2.2)调整清洁剂中的石油醚的含量;S2.2) adjust the content of petroleum ether in the cleaning agent;

S2.3)通过滴水角检测实验来评估调整石油醚含量后的清洁剂的清洁性能,如若评估合格,进入下一步;如若评估不合格,则进入步骤S2.2),并对前期已清洗的ITO玻璃再次进行清洗。S2.3) Evaluate the cleaning performance of the cleaning agent after adjusting the sherwood oil content by the drip angle detection experiment, if the evaluation is qualified, enter the next step; if the evaluation is unqualified, then enter step S2.2), and clean the previous stage The ITO glass is cleaned again.

通过对ITO玻璃清洗的首样和清洗过程中的定时抽检,确认ITO玻璃清洗的质量,如发现不合格,则通过调整清洁剂的配比并评估清洁剂的清洁性能来改善ITO玻璃清洗的洁净效果。Confirm the quality of ITO glass cleaning by checking the first sample of ITO glass cleaning and regular sampling during the cleaning process. If it is found to be unqualified, improve the cleanliness of ITO glass cleaning by adjusting the cleaning agent ratio and evaluating the cleaning performance of the cleaning agent. Effect.

具体的,步骤S3)中,质量控制标准为:取封胶干涸30分钟的电子显示屏各5pcs分别进行水煮实验和高温高湿实验,检测并确认经过两个实验的电子显示屏均无气泡出现。Specifically, in step S3), the quality control standard is: take 5pcs of each electronic display screen that has been sealed and dried for 30 minutes, and conduct a boiling test and a high-temperature and high-humidity experiment respectively, and detect and confirm that the electronic display screens that have passed the two experiments have no air bubbles Appear.

通过水煮实验和高温高湿实验来检测并确认完成步骤S3)的电子显示屏的质量,并以此验证采用清洁剂的清洗后的ITO玻璃的性能。The quality of the electronic display screen completed in step S3) is detected and confirmed through a water boiling test and a high temperature and high humidity test, and the performance of the cleaned ITO glass using a cleaning agent is verified thereby.

具体的,所述水煮实验的实验条件为:将待检测电子显示屏放入100℃的沸水中煮水2h,并以电子显微镜检测确认待检测电子显示屏中无气泡;Specifically, the experimental conditions of the boiling experiment are as follows: the electronic display screen to be tested is boiled in boiling water at 100°C for 2 hours, and an electron microscope is used to confirm that there are no air bubbles in the electronic display screen to be tested;
