Sony shows the thinnest OLED faceplate in the world Thickness is only 0.2 millimetres

On 2008 display unit big exhibitions that Japan hold, Japanese Sony has shown a section of thinnest OLED (organic luminescent diode) in the world Faceplate prototype, the thickness is only 0.2 millimetres.

Sony shows, OLED prototype size that develops newly is 3.5 inches, definition is that 320 looks like plain X 240 picture element, because picture element of OLED can oneself shiny, need other light source, so display unit that technology makes this very thin, the thickness is probably 1 millimetre to 2 millimetre.

The liquid crystal faceplate usually needs to adopt the rear-projection light source, thus increase the thickness of the faceplate. This means under engineering level that uses at present at least, the liquid crystal faceplate is unable to compete with OLED faceplate in reducing the thickness.

Sony first batch of OLED TVs named XEL-1 were put on market last year, XEL-1 TV adopted 11 inches of OLED faceplates. Thickness is only 1.4 millimetres. Because Sony hide in the intersection of television and base large part of a circuit, XEL-1 thickness of display unit 3 millimetres.

Compared with liquid crystal faceplate, OLED consumes lower energy. Except can reveal the picture moved fast, the picture color that OLED offers is very lifelike. A lot of faceplate manufacturers are developing OLED technology at present.

31 inches of OLED faceplates of Samsung The thickness is liquid crystal 1/10

Samsung SDI announces today, has already developed 31 inches of OLED (organic shiny second body display unit) Ultrathin faceplate. Samsung SDI reveals, prototype thickness of 31 inches of faceplates of its is only 4.3 millimetres, it is equivalent to 1/10 of the ordinary liquid crystal faceplate, electric consumption is less than half of 32 inches of liquid crystal faceplates; Life cycle is about 35,000 hours, the characteristics are the highest in existing AM-OLED. In November, the OLED TV with 11 -inch screen of Sony has just listed and sold, before this, Sony also showed OLED video prototype with 27 -inch screen. Further staging of competition of OLED market of entering making of 31 inches of OLED faceplates of Samsung. Samsung SDI refuses to reveal OLED video batch productino time with 31 -inch screen, only reveals that " consumes the electronic exhibition " in Las Vegas which Samsung will hold in next January (CES) Have and exhibit OLED video prototype with 31 -inch screen. In addition, the person in charge YooEui-jin of Samsung SDI Company AM-OLED business still reveals, the company will be in 14 inches of faceplates of batch productino of next year, many companies have already intended to purchase, but he refuses to announce the list. OLED is a kind of advanced display technology based on organic luminescent material and organic structure. This kind of technology adopts the unprecedented light and thin design, in order to reach the high-quality display effect. Meanwhile, there is OLED that still can offer more high contrast degree, luminance, the whole color to reproduce range and fast response time, in order to realize the good image quality. OLED display unit divided into the passive form (namely PM-OLED) in accordance with the driving means And active (namely AM-OLED) . Because there is relatively less AM-OLED electric consumption, the picture is more bright-colored, receive the favors of a lot of faceplate manufacturers. At present, some advanced mobile phone and media player have been already adopting the small-scale AM-OLED display screen, but it is difficult that there is technology in manufacture on larger display screen, and difficult to control the cost. Just because of this, Sony with 11 -inch screen the intersection of OLED and video the intersection of production and each control month in about 2,000 sets. And the beginning of this month, Toshiba is too high because of the cost of batch productino, cancelled and put out AM-OLED video plan from 2009 to 2010.

Fit full of trees and beautifully and push and is used in the double-output DC/DC that OLED faceplate supplies power

Fit the American semiconductor (ONSemiconductor) full of trees Introduced direct current of double-output of 2 watts a few days ago - the direct-flow converter NCP5810, offered the plus-minus output voltage. The intersection of output voltage and accurate high conversion frequency of device this and small dimension capsulate enable their particularly suit for organic luminescent diode (active matrix OLED or AMOLED) of active matrix The display of the faceplate drives and supplies power, for walkie application new developing display technology. Fit the American semi-conductive figure full of trees and consume to executive vice president and concurrently general manager ManorNarayanan of product division and say: "NCP5810 offers the advantage for electric power supply of AMOLED. It is devoted to designing the device with customer together fitting the American semiconductor full of trees, in order to meet their particular demand. NCP5810 is exactly a successful model of this kind of cooperation, it has already been selected to offer the power for new AMOLED display screen of the ultrathin walkie multimedia apparatus by the leading display unit manufacturer, and has already batch productino. " The latest display technology, OLED of active matrix, have the intersection of display unit and manufacturer of drib only batch productino this year and next year, but compared with present LCD display technology, it offers better color to compare with and the video sows quality, but add the challenge of power management for project engineering personnel. For example, in view of AMOLED display screen being very sensitive to the change of the service voltage, fitting the American semiconductor full of trees designs NCP5810, only offer the accurate feedback voltage of 1% of the voltage tolerance and fast circuit transient responses, and is inputting voltage fluctuation as 500 millivolts (mV) When, the transient overshoot voltage is only 4mV. In 1.75 MHZ (MHz) The whole power efficiency is up to 85% of the characteristics under the oscillator frequency, NCP5810 double-output direct current - direct-flow converter has offered the most excellent characteristic in the industry. For the fine and thin appearance of the complementary AMOLED display screen, the convertible high frequency to 1.75MHz of this converter, can use volume minor inductor and ceramic output capacitor. Thick to capsulate while being ultrathin 0.55mm its, make NCP5810 used in the thinnest walkie product design. In addition, its deenergization function under the shut-down mode, will let out revealing the electric current will be limited in 1 microampere (μ A) ,Have saved the battery power under the shut-down state. NCP5810 also has crest current restrictions and heat of Cycle by Cycle that shut down and protect the function. Capsulation and price NCP5810 adopts ultrathin 3.0mmx3.0mmx0.55mmLLGA-12 to capsulate, every batch unit price of 3,000 scenes is 1.20 dollars. Besides offering samples for NCP5810 device with the fixed converter output voltage, fit American full of trees semiconductor, offer, adopt the same encapsulated adjustable editions of sample of NCP5810A.
