Problems solved by technology
[0004] Please refer to Figure 1. The general method is to manually observe the amount of liquid crystal in the bottle during the operation of the machine, and judge whether the liquid crystal in the bottle needs to be replaced based on experience. However, when the height of the liquid crystal in the bottle is lower than a certain height , the pump will not easily suck out the liquid crystal in the bottle, and may even absorb air bubbles, resulting in poor brightness of the light source of the liquid crystal display; in addition, there are usually two ways to deal with residual liquid crystals, one is to put several bottles of liquid crystals with residual liquid crystals Bottles are poured into the same liquid crystal bottle, and then the liquid crystal bottle is reused, or the liquid crystal bottle with residual liquid crystal is sent back to the original factory for processing, but the above two processing methods are not suitable for liquid crystal with too much residual liquid crystal Bottles will have adverse effects. If there is too much residual liquid crystal remaining, when pouring it into the same liquid crystal bottle, it will increase the probability of liquid crystal being contaminated. In addition, if it is sent back to the original factory for processing, it will increase the cost of the company.

Embodiment Construction
[0023] see figure 2 As shown, the present invention comprises a liquid crystal containing device 14 and a sensing device 15, the liquid crystal containing device 14 has a body 16 and a bottle mouth 10, the bottom of the body 16 protrudes outwards to establish a base 18, and the base 18 There is an accommodating space 20 for containing a residual liquid crystal. In a preferred embodiment, the sensing device 15 is disposed near the base 18 and is used to detect the remaining amount of the residual liquid crystal in the accommodating space 20 .
[0024] see Figure 3A The body 16 includes a side wall that is arranged around the bottom of the body 16, wherein the corners 32, 38 between the bottom of the body 16 and the side wall present an arc shape, and the base 18 has a side wall, and the side wall and the body 16 The bottom of the bottom has a corner 34, 36 which also presents an arc shape, so that the residual liquid crystal is easy to flow into the accommodating space 20 to...

Abstract
The invention mainly relates to a warning system, in particular to a liquid crystal residue warning system which comprises a liquid crystal accommodation device; the liquid crystal accommodation device is provided with a body, a base is convexly arranged outwards at the bottom of the body, the base is provided with an accommodation space used for containing residual liquid crystal, and the internal diameter of the base is not more than that of the body; in addition, a sensing device is arranged near the base and used for sensing the residual volume of the residual liquid crystal in the accommodation space. The warning system can not only reduce the residual volume of the liquid crystal and the cost consumption of companies, but also avoid the probability that the liquid crystal is polluted when all residual liquid crystals are collected into another accommodation device.
Description
technical field [0001] The invention mainly relates to a warning system, in particular to a liquid crystal residual warning system. Background technique [0002] Liquid crystal is a material that has both the fluidity of liquid and a certain regular arrangement of crystals, so it is called liquid crystal. Liquid crystal molecules are easy to flow due to external force, and have anisotropic characteristics similar to uniaxial crystals, that is, materials The optical refractive index, dielectric constant, magnetic susceptibility, and viscosity of the material will vary with different directions. Therefore, in many applications, after the liquid crystal molecules are stimulated by the outside world, the arrangement of the molecules will change, resulting in changes in its optical or electrical properties, and this material is used in displays, optoelectronic components, and sensors, etc. component. [0003] In the TFT LCD industry, liquid crystal is one of the important direc...
