平面顯示器具有許多技術，可使得視訊顯示器較使用 ，極射線管的傳統電視及視訊顯示器輕薄，且小於1〇公 =(4叶)厚度。需要連續更新的平面顯示器包含液晶顯示 ，(LCDs)、電漿顯示器、場發射顯示器(FEDs)、有機發光 二極體顯示器（OLEDs)、表面傳導電子發射顯示器 (SEDs)、奈米發射顯示器(NEDs)、以及電致發光顯示器 (ELDs) ° 液晶顯示器(LCD)係為薄型平面顯示裝置，其係由任 何數目的顏色及單色像素排列組成於光源或反射器前。液 晶顯示器廣為使用是因為其耗用非常少量之電力。 一種作為液晶顯示器的液晶面板係由以下方法所製 造。 、 $成彩色濾光片以及共同電極的圖形於一上方玻璃 基板。薄膜電晶體(TFT)以及像素電極的圖形形成於相對 於上方玻璃基板之下方玻璃基板上。摩擦配向層使得兩配 向層之間的晶體分子具有預傾角以及方向。 6 200831191 點膠機用於形成膠圖形於上方或下方玻璃基板的任 一個上’用以密封液晶層於上方及下方玻璃基板之間。因 此，LC點膠機用於塗佈液晶於膠圖形所形成的玻璃基板 上。上方及下方玻璃基板組合完成液晶面板。上方及下方 玻璃基板於劃線及裂片操作期間分離成離散面板。 ^點膠機包含一台座，一塗佈頭單元，以及支撐塗佈頭 單元的塗佈頭支撐單元框架。塗佈頭單元包含帶 注射器以及塗佈液晶之喷嘴。 曰的 當噴嘴與基板之間保持固定距離時，藉由在γ ，，基板的台座，藉由在χ軸方向移動塗佈頭軍元， 或糟由於Χ·Υ軸方向移動兩者，點膠機 形成膠_於基板上。 冑U得以 當塗佈膠時，在注射器内剩餘的膠慢慢減少。注射哭 可能在___，使得_形不完ί的形=Flat-panel displays have a number of technologies that make video displays more compact, traditional TV and video displays for polar tubes, and less than 1 = = (4 leaves). Flat-panel displays requiring continuous updates include liquid crystal displays, (LCDs), plasma displays, field emission displays (FEDs), organic light-emitting diode displays (OLEDs), surface conduction electron-emitting displays (SEDs), and nano-emissive displays (NEDs) ), and electroluminescent displays (ELDs) ° Liquid crystal displays (LCDs) are thin flat-panel display devices consisting of any number of colors and monochromatic pixel arrangements in front of a light source or reflector. Liquid crystal displays are widely used because they consume a very small amount of power. A liquid crystal panel as a liquid crystal display is manufactured by the following method. , a color filter and a common electrode pattern on an upper glass substrate. A pattern of a thin film transistor (TFT) and a pixel electrode is formed on the glass substrate below the upper glass substrate. The rubbing alignment layer causes the crystal molecules between the two alignment layers to have a pretilt angle and a direction. 6 200831191 The dispenser is used to form a glue pattern on either the upper or lower glass substrate to seal the liquid crystal layer between the upper and lower glass substrates. Therefore, the LC dispenser is used to coat liquid crystal on a glass substrate formed by a glue pattern. The upper and lower glass substrates are combined to complete the liquid crystal panel. The upper and lower glass substrates are separated into discrete panels during scribing and splitting operations. The dispenser includes a seat, a coating head unit, and a coating head support unit frame that supports the coating head unit. The coating head unit includes a nozzle with a syringe and a liquid crystal coating. When the nozzle is kept at a fixed distance from the substrate, by moving the coating head armature in the y-axis direction at y, the pedestal of the substrate, or by moving both in the direction of the Χ·Υ axis, dispensing The machine forms a glue on the substrate.胄U is able to reduce the amount of glue remaining in the syringe as it is applied.

Install the measuring device to generate the purchase cost, and also need to adjust the position. It is important to not have a flat, and it is important to decide when to replace the financial face shot with a new injection 7 200831191. Too early replacement is a waste of glue, too late replacement causes incomplete pattern formation on the substrate. It is important to accurately measure the amount of glue remaining in the syringe as accurately as possible. When the amount of remaining glue measured in the syringe in the gas use is different from the actual amount of glue, L cannot apply a specific amount of glue. This is because the amount of pressure applied to the glue in use is varied with the amount of glue remaining in the syringe. 2. The amount of glue remaining in the syringe in use is greater than the amount actually remaining in the syringe. When higher than normal pressure is applied to the glue, more glue is applied. When the syringe in use measures the amount of glue remaining less than the amount actually left in the injection H, a lower than normal pressure is applied to the glue, so less glue is applied. L invention content] if t the purpose of the invention is to make a method of injecting 11 minutes of glue, : 摅太』 should be a unit, instead of installing the level of the remaining amount of the device c, provide a syringe for measuring the dispenser Remaining, 丄, by; using (the second third = = ^ 3 (four) two time amount) ratio, measuring the remaining in the syringe of the financial 200831191 ... and the other purposes, features, levels and advantages of the present invention The following detailed explanations and accompanying drawings will become apparent and easy to see. [Embodiment] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. σ • A schematic diagram of a dispenser using a method of measuring residual glue in the main shot in use in accordance with a specific embodiment of the present invention. The dispenser 100 includes a coating head support frame 1〇2 which is slidable in one direction, for example, in the X-axis direction. The coating head unit is provided to the coating head support frame 102' such that it can slide in a direction perpendicular to the moving direction of the coating head supporting frame 1〇2 (e.g., in the Y-axis direction). A nozzle ln for applying a glue is provided to the coating head unit 110. Therefore, the nozzle lu can be moved in the X-axis direction and the Y-axis direction with respect to the substrate so as to maintain a fixed distance between the nozzle 111 and the substrate 10. ® , Dispenser 100 contains a pressure supply unit. The pressure supply unit supplies a pressure equalizing gas to the syringe 112 until the syringe 112 is pressurized to a target pressure (TP) that is dispensed to the substrate 10 via the nozzle ηι. The pressure supply unit includes a regulator 121, a valve 122, and a sensor 123. Regulator 121 provides a gas, such as air or nitrogen, and pushes the gas into the syringe at a constant pressure. The valve port 22 controls the flow of gas from the regulator 丨 21 to the injector 112. 200831191 The sensor sensor 123 senses the amount of pressure provided to the syringe 112. Therefore, when the throttle 121 supplies the pressure equalizing gas, the sensor 123_injector 112 Z is pressurized to the target pressure (TP). The supply of gas is controlled based on the pressure from the sensor 123.

When the glue is applied through the nozzle 111, the amount of the syringe m_gel is reduced by two. The amount of pressure of the syringe 112 varies with the amount of meat remaining in the syringe 112. Therefore, before and after coating, you need to measure the syringe! 12 to _112 _ force to pressurize the target pressure of the Tianhe mouth 111 on the substrate 10. A specific embodiment of the remaining hair strands' illustrates the measurement of the time change of the syringe 112.

And the empty syringe does not contain glue. Select the pressure range of the pressure within the injection period to select the f test, force (RP). By using the pressure inside the syringe to change the stability of the time 'by taking the amount as accurately as possible The residual glue in the syringe is measured.
