Embodiment Construction

[0018] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments. Such as figure 1 As shown, a system of the present invention that effectively solves the unclear display of liquid crystal display screens under sunlight includes photosensitive sensors connected in sequence for identifying the light intensity of the external environment

[0019] 1. A central processing unit for analyzing and processing the ambient light brightness data sent by the photosensitive sensor. 2. A liquid crystal display module 3 for completing image display.

[0020] A method of effectively solving the unclear display of the liquid crystal display under the sun of the present invention specifically includes the following steps:

[0021] 1. The photosensitive sensor 1 recognizes the ambient light intensity, and transmits the collected ambient light brightness data to the central processing unit 2 .

[0022] 2. The central processing unit ...

Abstract

The invention discloses a system for effectively solving the problem of unclear display of a liquid crystal display screen under the sunshine. The system comprises a photosensitive sensor, a central processor and a liquid crystal display module which are connected in sequence, wherein the photosensitive sensor is used for recognizing the light intensity of the external environment; the central processor is used for analyzing and processing the light brightness data of the environment and data to be displayed; the liquid crystal display module is used for finishing image display. A method disclosed by the invention comprises the following steps of: utilizing the photosensitive sensor to recognize the light intensity of the external environment accurately, recognizing the contrast of the current original image by the processor, processing the display data of the original image according to the light intensity of the external environment, and changing the gray value of the original image so as to increase the contrast and the definition of the original image. The invention has the advantages that the problem of unclear display of the liquid crystal display screen under the sunshine is solved by a data processing algorithm, serious distortion of the image can not be caused, the backlight brightness is adjusted by combining the environmental light and the image data, the power is saved compared with the mode of singly combining the environmental light to adjust the backlight brightness, and the purpose of furthest saving power under the premise of meeting the visual condition can be realized.

Description

technical field [0001] The invention relates to a method and system for effectively solving the unclear display of a liquid crystal display under sunlight. Background technique [0002] At present, the LCD screens of traditional mobile handheld devices are mainly divided into two categories: LCD screens and OLEDs. Due to the limited maximum luminance of the display module itself, it generally cannot meet the needs of users to browse the displayed content outdoors under strong light. In order to be able to To see the content displayed on the screen clearly, the general method is to increase the brightness of the screen at the expense of power consumption. The consequence of the increase in power consumption is the shortening of the use time. [0003] The patent with the publication number CN102201217A is a method for eliminating residual image and flicker of the liquid crystal screen. The method adjusts the common voltage of the liquid crystal display to the middle value of t...
