Method and system for effectively solving problem of unclear display of liquid crystal display screen under sunshine

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 screen 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 luminous brightness of their display modules, they generally cannot meet the needs of users to browse and display content outdoors under strong light. To see the contents of the screen clearly, the general method is to sacrifice power consumption to increase the screen brightness. The consequence of the increase in power consumption is the shortening of the use time. [0003] The patent with publication number CN102201217A is a method to eliminate the residual image and flicker of the LCD screen. The method adjusts the common voltage of the LCD screen to the middle value of the video signal voltage value interval, and the driving device o...
