Problems solved by technology

[0005] In the prior art, the display pixels of a transparent liquid crystal display usually include red, green and blue sub-pixels and transparent sub-pixels, wherein the red, green and blue sub-pixels form a display area to provide a display image for viewers to watch, while the transparent sub-pixels are in a transparent state so that The viewer can see the scene behind the transparent area, and the rotation of the liquid crystal corresponding to the transparent sub-pixel needs to be independently controlled, because if the independent control is not performed, when the signal of the pixel electrode changes, the corresponding liquid crystal of the transparent sub-pixel The liquid crystal changes accordingly, so that the pixels with higher gray levels of the input signal have stronger transmittance, and the places with black screens have the lowest transmittance
This does not meet the display requirements for transparent displays

Embodiment Construction

[0035] In order to further illustrate the technical means adopted by the present invention and its effects, the following describes in detail in conjunction with preferred embodiments of the present invention and accompanying drawings.

[0036] see figure 1 , and combined with figure 2 , the invention provides a kind of data processing method of transparent liquid crystal display, comprises the following steps:

[0037] Step 1. Provide a transparent liquid crystal display, including: a plurality of display pixels arranged in an array, and each display pixel includes: a red sub-pixel 1, a green sub-pixel 2, a blue sub-pixel 3, and a transparent sub-pixel Pixel 4.

[0038] Specifically, the red sub-pixel 1, the green sub-pixel 2, the blue sub-pixel 3, and the transparent sub-pixel 4 are all driven by an independent thin-film transistor for displaying, and the pixels of each sub-pixel are controlled by each thin-film transistor. The electrode voltage controls the liquid cryst...

Abstract

The invention provides a data processing method of a transparent liquid crystal display. The method calculates the color saturation of each display pixel according to the grayscale values ​​of the red sub-pixel, green sub-pixel, and blue sub-pixel in each display pixel, and then calculates the color saturation of each display pixel according to the color saturation Select the corresponding calculation formula to calculate the grayscale value of the transparent sub-pixel. When the color saturation is low, the transmittance of the transparent sub-pixel is increased. When the color saturation is high, the transmittance of the transparent sub-pixel is reduced. When the saturation is in the middle region, the transmittance of the transparent sub-pixels is balanced to realize real-time adjustment of the transmittance of the transparent area in the transparent liquid crystal display and improve the display effect of the transparent liquid crystal display.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a data processing method for a transparent liquid crystal display. Background technique [0002] With the development of display technology, various new technologies are constantly emerging, and transparent display technology has attracted more and more attention because of its transparent display panel and its unique applications. [0003] A transparent display generally refers to a display that can form a transparent display state so that the viewer can see the image displayed on the display and the scene behind the display. Transparent displays have many possible applications, such as windows in buildings or cars and display windows in shopping malls. In addition to these large device applications, small devices such as handheld tablets can also benefit from transparent displays, for example, enabling users to view maps and see through the screen to what is ahead.
