Embodiment Construction

[0017] Such as figure 1 with figure 2 The liquid crystal display light transmittance fast detection method based on the JDL model as shown comprises the following steps:

[0018] 1) Control the light transmittance tester to emit a variety of lights to irradiate the liquid crystal display, and collect the light transmittance of various lights after the liquid crystal display is irradiated by the data acquisition and processing unit. filter the rate data, and then send the processed data to the light transmittance rapid evaluation unit;

[0019] 2) The transmittance rapid evaluation unit classifies and integrates the transmittance data of various lights sent back by the data acquisition and processing unit, and converts them into a data array suitable for calculation by the JDL model fusion method;

[0020] 3) Then the light transmittance rapid evaluation unit adopts the JDL model fusion method to quickly evaluate the light transmittance of the above data. The specific proces...

Abstract

The invention discloses a JDL-model-based rapid transmittance detection method for a liquid crystal display screen. The method is characterized by comprising the following steps: controlling a transmitivity test apparatus to emit various lights irradiated to the liquid crystal display screen, acquiring the transmitivity after various lights are irradiated to the liquid crystal display screen through a data acquisition processing unit, simultaneously filtering the transmitivity data of various lights through the data acquisition processing unit, and sending the processed data to a transmittance rapid evaluation unit; then rapidly evaluating the transmittance on the data by using a JDL model fusion method through the transmittance rapid evaluation unit; and finally sending a transmittance rapid evaluation result to a detecting and monitoring central computer through the transmittance rapid evaluation unit and further processing the result through a computer central processing unit. The method further has the characteristics of being convenient to use, rapid to process, easy in technological implementation and the like, and is suitable for wide popularization.

Description

technical field [0001] The invention relates to a method for quickly detecting the light transmittance of a liquid crystal display screen based on a JDL model. Background technique [0002] Light transmittance is the percentage of luminous flux passing through a transparent or translucent body to its incident luminous flux. Indicates the efficiency of light transmitted through display devices, etc., which directly affects the visual effect of the touch screen. Many touch screens or liquid crystal displays are multi-layer composite films. It is not enough to summarize its visual effect with transparency. It should include at least four characteristics: transparency, color distortion, reflectivity and clarity. For example, the degree of reflection includes the degree of specular reflection and diffraction reflection, but the diffraction reflection on the surface of the LCD screen has not yet reached the level of a CD disc. For users, these four characteristics are basically e...
