Abstract
A field sequential driven color liquid crystal display with high transmittance comprises more than two types of backlights with different colors and a field sequential driven backlight drive circuit, a liquid crystal display, and a liquid crystal display drive circuit of the liquid crystal display. The liquid crystal display is a scattering type liquid crystal display with transmittance greater than or equal to 70%, the backlights are arranged on the side lower portion of the liquid crystal display, emitting light of the backlights radiates slantingly to the liquid crystal display, and the liquid crystal display is a scattering type liquid crystal display without polarizer. The color liquid crystal display adopts the liquid crystal display with the transmittance greater than or equal to 70%, and the liquid crystal display is a scattering type liquid crystal display without polarizer, thereby greatly improving the transmittance of the color liquid crystal display. In addition, the color liquid crystal display adopting field sequential drive is low in cost.
Description
Technical field
The utility model relates to a kind of field sequence driven colour liquid crystal display of high transmission rate.
Background technology
Present colour liquid crystal display device generally all includes colour film, this class colour liquid crystal display device, and in the time of theoretically, its transmittance is below 50%.In order to improve the transmittance of colour liquid crystal display device, also can reach energy-conservation and effect low price, a kind of the LCD that preface drives appearred on the market, adopted TN at a high speed and AFLC can reach the display effect that a preface drives in these several years recently, than the saturating high rate height of the liquid crystal display of former color film mode.But these LCD still can not break through 50% transmittance theoretically owing to still will adopt polaroid.In recent years, required to use transmittance more and more,, adopt the colour liquid crystal display device of high transmission rate as wrist-watch near the purposes of the LCD of simple glass.Also having a purposes is the interior display of using on the single-lens reflex camera of view-finder, also requires the colour liquid crystal display device of high transmission rate, needs its transmittance more than 70%, and does not allow polarisation.So existing high speed TN and AFLC colour liquid crystal display device are obsolete.
The utility model content
The utility model provides a kind of polarity of not having to society, and transmittance can reach the field sequence driven colour liquid crystal display of the high transmission rate more than 70%.
The technical solution of the utility model is: designs a kind of field sequence driven colour liquid crystal display of high transmission rate, comprises backlight with different colours more than 2 kinds, and the backlight source driving circuit of a preface driving; LCDs and LCDs driving circuit thereof, described LCDs are transmittance more than or equal to 70% scattering type liquid crystal display screen; Described backlight is arranged on the side-lower of LCDs, the described LCDs of the oblique directive of ejaculation light of backlight; Described LCDs is not establish the scattering type liquid crystal display screen of polaroid.
The scattering type liquid crystal screen that described scattering type liquid crystal screen is a DS mode (Dynamic Scattering Mode).
Described scattering type liquid crystal screen is a PDLC scattering type liquid crystal screen.
Described more than 2 kinds the backlight of different colours be 3 look backlights.
Described backlight is LED, CCFL or OLED.
The utility model since adopted LCDs be transmittance more than or equal to 70%, and do not have the scattering type liquid crystal display screen of polaroid, so improved the transmittance of colour liquid crystal display device greatly; Adopt a preface to drive, so it is cheap.
