Embodiment Construction

[0012] The technical solution provided by the present invention is to add a focusing light metering device to the TV to detect the light reception data of human eyes and face, and transmit the light reception data to the TV CPU after processing. The CPU judges whether the focus is accurate or not according to the light reception data. The focus metering device needs to be adjusted; and the backlight of the TV is adjusted according to the light reception data of the human eyes and face detected by the focus metering device when the focus metering device is accurate.

[0013] In order to make the objectives, technical solutions and advantages of the present invention clearer, the following further describes the present invention in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

Abstract

The invention is suitable for the technical field of televisions, in particular provides a television and a backlight-adjusting method thereof. The television comprises an optical receiving device, an image sensor, a signal-processing converter, a CPU and a backlight control module, wherein the optical receiving device is used for receiving light reflected by the eyes of television viewers and transmitting the received light to the image sensor which is used for receiving the light transmitted by the optical receiving device, generating an optical signal according to the strength of the received light and outputting the optical signal to the signal-processing converter; the signal-processing converter is used for converting the optical signal transmitted by the image sensor into a digital signal and outputting the digital signal to the CPU; and the CPU is used for comparing a numerical value of the digital signal with a set standard regional value, calculating adjusting data according to the compared different value and inputting the adjusting data into the backlight control module which is used for adjusting the backlight of the television according to the adjusting data.

Description

Technical field [0001] The invention belongs to the technical field of televisions, and particularly relates to an LCD television with adjustable backlight and a backlight adjustment method thereof. Background technique [0002] At present, the backlight adjustment of LCD TVs rarely takes into account the influence of external light on backlight adjustment. There are also a few products that use some photosensitive devices to automatically adjust the backlight according to changes in ambient light, thereby reducing user eye fatigue and protecting users’ eyesight. At the same time, it can also save energy. In the prior art, some LCD TVs adjust the backlight of the TV by testing the brightness of the ambient light, that is, install a light sensor that can detect the brightness of the ambient light for the TV, and collect some parameters that help adjust the brightness of the backlight. , The collected parameters are sent to the CPU preset with the analysis processing program, and t...
